The Hybrid strategy combines the advantages of Contour3D with the Scallop and Parallel strategies enabling users to easily create cutting passes for both steep and shallow areas in a single operation.
Users often prefer Contour3D for machining steep areas and Scallop or Parallel for shallow areas. However, this approach requires that several operations are created and that machining angles, contact boundaries and machining boundaries are configured. This is time consuming and often the ordering of toolpaths will not be optimal.
The new Hybrid strategy provides an alternative which is much easier to configure and that ensures optimal toolpath ordering.
In the large area, the tool is selected, or a new tool can be created from the right click menu. The fields below are automatically updated from the tool selected above. The tool drawing to the right is updated each time a field is exited, to reflect the changed value. The right click menu is also used to access the HSM tool library, described below.
The flute length doesn't have an effect on the shape of the cutter paths unless a taper angle is applied. Tapered tools add the shape of a cone of the given taper angle from the vertical axis. The bottom of the (truncated) cone is tangential to the shape at the tip, and the top is at the flute length above the tip. For tapered tools, the tool definition is straightforward for ball nosed and flat bottomed tips, but for bull nosed tips the standard convention is more complicated: the shaft diameter refers to the diameter of the bottom of the conical surface and not the diameter of the virtual toroidal shape that would be within the tapered shape.

In the section Shaft and holder you can define holder and shaft collision checks and how the toolpath should respond to detected collisions. In particular, this is where you can define to tilt the tool in case of a collision, effectively creating a 5-Axis toolpath.
Note that these collision checks require additional calculation time when the toolpath is generated, but ensures that the shaft and holder do not collide with the part if used.
The following parameters can be set to control the collision detection (note that not all parameters are available for all strategies):
Collision detection policy
The dropdown menu lets you select how HSM Performance Pack should react to a detected holder collision. The following options are available (depending on the selected strategy):
Ignore
With the option Ignore, collisions between the shoulder, shank, holder and the work piece are ignored.
Trimming
When the trimming option is selected, toolpath will be trimmed away in areas of holder collisions.
Tilt to avoid collision
With this option, the tool is tilted far enough so that it can make the cut without having the holder collide with the part. Only toolpath with a ball nose mill can be tilted. This mode is supported for finishing strategies.
Detect length
With the option detect lenght, HSM Performance Pack checks toolpath and suggests a flute length to the user for which any holder collisions are avoided.
A warning such as the following will be provided to suggest a tool:
“Warning: Tool flute must be increased by 53.04 to avoid holder gouge.”
Fail on collision
With the option fail on collision, the toolpath generation fails in case the software detects a holder collision.
The following is an example error which is provided to help the user in removing the gouge:
“Error: Holder Gouge detected at point (37.7439,-57.5288,0), tool axis: (0,0,1), linking path #102”
Holder clearance
The Holder clearance defines the safety distance between the holder and the stock. If the holder gets closer to the part (or stock) than this distance, it will be treated as a collision.
Shank clearance
The Shank clearance defines the safety distance between the shank and the stock. If the shank gets closer to the part (or stock) than this distance, it will be treated as a collision.
Max segment length
Specifies maximum allowed distance between neighboring points in toolpath after tilt.
Max axis change
Specifies maximum allowed tool axis change between neighboring points in toolpath after tilt.
Tilt angle deviation +/-
The option tilt angle deviation +/- allows you to set the maximum allowed tilt angle in both directions away from the the vertical position.
Fan distance
Specify the smoothing distance that should be applied in the tilt algorithm. Bigger value provide smother toolpath after tilt.
|
Clearance height
The Clearance height defines the first height to which the tool moves before the start of the toolpath. The height is relative to the top of the surface to be machined.
The field Absolute clearance height can be enabled to define an absolute Z value instead.
Retract height
The Retract height defines the height to which the tool retracts between cutting passes. The linking moves at this height are carried out at rapid speed. The height is relative to the top of the surface to be machined.
The field Absolute retract height can be enabled to define an absolute Z value instead.
Safe distance
The Safe distance defines the minimum distance between the tool and the part surfaces during shortest path retract moves. This distance is measured after the stock to leave has been applied, so if a negative stock to leave is used, special care should be taken that the safe distance is large enough to ensure that no collisions occur.
Retraction policy
The Retraction policy determines how moves between cutting passes are done. Shortest path is the shortest possible path (which often includes moves in all three axes), Minimum retraction is straight up to the lowest height where the tool will be clear of the part (by safe Z distance), and Full retraction is to the clearance plane.
Allow rapid retract
By enabling Allow rapid retract, vertical retract moves will be carried out at rapid speed. If this is not enabled, retracts will be carried out at the lead-out feedrate.
Explicit lead out
By enabling Explicit lead out you can define the lead out parameters independently from the lead in parameters. If not enabled, the lead out parameters will be identical to the lead in parameters.
Perpendicular lead
By enabling Perpendicular lead you can define that a movement which is perpendicular to the lead-in/out arc should replace tangential extensions of arcs.
Perpendicular lead out
By enabling Perpendicular lead out you can define that a movement which is perpendicular to the lead out arc should replace tangential extensions of arcs.
Vertical lead radius
A lead-in or out movement generally consist of three components. The horizontal lead-in/out arcs which is located in the perpendicular plane to the tool start axis and leading smoothly into or away from the toolpath, followed by a linear segment in the same plane, and a vertical arc connecting the linear segment with the retract movement.
Vertical lead radius defines the radius of the vertical arc component of the lead-in/out movement. The radius can be specified as a percentage of the tool diameter or as an absolute value.
Vertical lead out radius
Vertical lead out radius defines the radius of the vertical arc component of the lead-out movement. The radius can be specified as a percentage of the tool diameter or as an absolute value. You need to enable Explicit lead out in order to specify a separate vertical lead out radius. Otherwise, the same radius will be used for lead-in and lead-out.
Horizontal lead radius
Horizontal lead radius defines the radius of the horizontal arc component of the lead-in/out movement. The radius can be specified as a percentage of the tool diameter or as an absolute value.
Horizontal lead out radius
Horizontal lead out radius defines the radius of the horizontal arc component of the lead out movement. The radius can be specified as a percentage of the tool diameter or as an absolute value. You need to enable Explicit lead out in order to specify a separate horizontal lead out radius. Otherwise, the same radius will be used for lead-in and lead-out.
Sweep
Sweep defines the sweep angle between the linear segment component of the lead-in/out movement and the toolpath.
Sweep (lead out)
Sweep (lead out) defines the sweep angle between the linear segment component of the lead out movement and the toolpath. You need to enable Explicit lead out in order to specify a separate lead out sweep angle. Otherwise, the same angle will be used for lead-in and lead-out.
Linear lead distance
Linear lead distance defines the length of the linear segment component of the lead-in/out movement.
Linear lead out distance
Linear lead out distance defines the length of the linear segment component of the lead-in/out movement. You need to enable Explicit lead out in order to specify a separate linear lead out distance. Otherwise, the same distance will be used for lead-in and lead-out.
Keep down distance
The Keep down distance defines a length below which retracts are avoided. This means that lead-in and lead-out moves are still generated below this length, but the tool is only lifted up slightly.
Max transition distance
Use the parameter Max transition distance to define a maximum allowed length for transitions between cutting passes. If the distance between two passes is greater than the Max transition distance, the tool retracts or is lifted up and a lead-out and lead-in are generated.
Contact ramp policy
From the dropdown menu contact ramp policy you can select the method by which ramps should be carried out between different cutting depths. The available options are:
Straight line: This defines that the transitions are simple straight lines between two cutting passes.
Curve: In this mode, the transitions are smooth curves which are tangential to the cutting passes at both ends of the transition.
Loop: This creates a loop away from the surface of the part in order to maintain the machine dynamics when ramping down.
Disabled: This disables transition moves.
Contact ramp angle
The contact ramp angle is the angle which the ramp forms with the cutting passes. A smaller angle means that the ramp into the material is less steep.
|
Tolerance
Tolerance defines the maximum value the toolpath is allowed to deviate from the surface of the input geometry. A small tolerance value yields more precise toolpaths at the expense of longer computation times.
Stock to leave
Stock to leave is the stock to leave in the X/Y plane, i.e. in the plane vertical to the tool direction. Stock to leave offsets the tool away from walls and tilted surfaces by the specified distance.
Axial stock to leave
Axial stock to leave defines the stock to leave in the Z-direction, i.e. in the direction along the tool axis. Axial stock to leave lifts the tool up from the surface by the specified distance.
Stock to leave on check
Stock to leave on check is the stock to leave on check surfaces in the X/Y plane, i.e. in the plane vertical to the tool direction. Stock to leave offsets the tool away from walls and tilted surfaces by the specified distance.
Axial stock to leave on check
Axial stock to leave on check defines the stock to leave on check surfaces in the Z-direction, i.e. in the direction along the tool axis. Axial stock to leave lifts the tool up from the surface by the specified distance.
Spiral
Activate the option spiral to perform the contour operation in one continuous spiral. This means that the toolpath will spiral downwards continuously without any transitions for a superior surface finish. If spiral is not activated the toolpath will be carried out as a traditional contour with constant z-levels.
Machine steep first
When the option Machine steep first is activated, all contour passes are machined first. Afterwards all parallel/contour passes.
Note: This option can only be used with the Trim method in Hybrid.
This settings area contains options for contour passes.
Stepdown
The stepdown is the maximum vertical distance between two cutting levels. Note that the actual stepdown may be less than the value specified in stepdown. This is because HSM Performance Pack will automatically reduce the stepdown to ensure that cuts are carried out at the minimum depth and maximum depth, and that all Z-level cuts are spaced evenly.
|
Example of the Stepdown. The Stepdown is indicated by the gab between the two cutting levels (the arrow), which are the two planes with pink paths. |
The parameter can be used as a variable in formulas by entering MaximumStepdown.
Direction
With the dropdown menu direction you can specify in which direction the tool will move along the surface. You can select climb milling, conventional milling or both ways.
|
Climb milling means that the direction of the work piece relative to the tool is in the same direction as the tool rotation. |
|
In conventional milling, the work piece motion relative to the tool is in the opposite direction of the tool rotation. |
Selecting both ways specifies that there is no preference between climb and conventional milling. In this case, HSM Performance Pack will choose the cutting direction such that the toolpath length is minimized.
In general climb milling is commonly used since the chips are thrown away from the tool. For conventional milling, they land in front of the tool. Due to this, climb milling leads to better surface finishes and less to wear. However, there may be cases when conventional milling is the better choice due to backlash in climb milling.
Machine shallow areas
Activate machine shallow areas to add additional cuts in shallow regions of the geometry by dynamically reducing the stepdown in shallow regions.
Minimum stepdown
The minimum stepdown is the smallest possible vertical spacing between two cutting levels. When machine shallow areas is used, the minimum stepdown ensures that HSM Performance Pack does not add extremely narrow cutting levels in almost flat regions of the geometry. HSM Performance Pack tries to ensure a stepover smaller than the stepover, but only as long as the stepdown is bigger than the minimum stepdown.
Stepover
The stepover is the maximum horizontal spacing between cuts of two next cutting levels. This criterion is used to add additional cutting levels when machine shallow areas is activated: HSM Performance Pack reduces the stepdown to ensure that the stepover does not exceed the stepover. Note that the stepdown will never be reduced to less than the minimum stepdown.
Order by depth
When the option order by depth is activated, the cuts are ordered by the depth at which they are carried out. If the option is deactivated, the cuts are ordered by pocket, i.e. a single pocket is milled all the way at different depths before the tool moves to the next pocket.
Detect flat areas
Detect flat areas ensures that flat regions in the geometry are detected by adding additional Z-level slice between the regularly spaced cutting levels.
Ignore flat areas
Allows to ignore flat areas when machining shallow regions. It useful when user wants to machine them later using different tool with Horizontal strategy.
Use next tool
If Use next tool option is enabled it assumes that flat areas will be machined in next operation with different tool.
Next cutter diameter
Next cutter diameter is the diameter of the next tool.
Next cutter corner radius
Next cutter corner radius is the corner radius of the next tool.
From slope angle
In the selection box from slope angle you can specify the lower limit of slope angles below which no toolpath will be generated.
To slope angle
In the selection box to slope angle you can specify the upper limit of slope angles above which no toolpath will be generated.
Confine depth
Activate confine depth to specify depth limits for the toolpath, useful for machining deep pockets, where the upper areas are to be machined with a shorter tool, and the lower areas with a longer tool.
Minimum depth
The minimum depth is the height at which the cuts begin.
Maximum depth
The maximum depth is the final cutting depth of the operation.
This setting area contains option for parallel/scallop passes.
Strategy
This options allows to select machining approach for shallow regions.
Parallel: Parallel passes are used for machining shallow regions.
Scallop: Scallop passes are used for machining shallow regions.
Method
This options allows to specify when machining approach should be switched from steep to shallow. Depending on selected strategy the following options are available:
Closed
With these settings, HSM Performance Pack begins by automatically creating contour passes based on the specified stepdown value (Maximum stepdown). Only those where distances between passes does not exceed the Maximum stepover value are kept. Next, using the contour passes as boundaries, the empty areas are 'filled' with scallop toolpaths.
Trim
With these settings, HSM Performance Pack uses the Shallow angle value to automatically define machining boundaries that determine in which areas contour and scallop passes are created.
Fixed direction
With these settings, HSM Performance Pack uses the Shallow angle value to automatically define machining boundaries that determine in which areas contour and parallel passes are created. Directions for parallel passes are determined by provided machining angle.
Automatic direction
With these settings, HSM Performance Pack uses the Shallow angle value to automatically define machining boundaries that determine in which areas contour and parallel passes are created. Directions for parallel passes are selected automatically for each shallow area.
Stepover
The stepover is the distance between two cutting passes. The stepover must always be less than or equal to the tool diameter since otherwise the toolpath might leave stand-ups between cutting passes.
Shallow angle
Determines angle where switch between shallow and steep regions should be.
Note: Not available in Scallop-Closed mode.
Direction
From the dropdown menu direction you can select in which directions shallow passes are allowed to cut. You can choose between one way, other way and both ways.
One way
The option one way defines that shallow cuts will be taken in the same direction.
Other way
The option other way defines that shallow cuts will be taken in the same direction, but opposite of one way.
Both ways
If both ways is selected the shallow cuts will be carried out in both directions along the surface. The parallel passes are linked with smooth linking arcs (if curve transitions are activated). both ways is the most common selection and usually results in the shortest toolpath.
Add center passes
When enabled, additional passes are added into offset collapse areas to preserve the specified stepover.
Smoothing value
Applies provided smoothing to toolpaths. Allows for much faster tool movements since sharp corners are prevented.
Note: Available only if Scallop is selected for machining shallow regions.
Overlap
Overlap value specifies how much steep and shallow passes can overlap. This ensures removing all material on the border between steep and shallow areas.
Inside out (Link from inside to outside)
Link from inside to outside means the tool starts at the midpoint, machining from there out to the toolpath boundary, instead of starting at the toolpath boundary and machining in towards the midpoint.
Note: Available only if Scallop is selected for machining shallow regions.
Machine areas using boundaries
With machine areas using boundaries you can select the way in which Hybrid handles restrictions on the toolpath. If machine areas using boundaries is activated, it will first calculate the contours of the prohibited areas, and use them as a machining boundaries for all hybrid passes. If machine areas using boundaries is not activated, it will generate Hybrid toolpath on the entire selected geometry, and subsequently trim away all prohibited areas. The selected approach is used if the heights are set up to restrict the toolpath to certain areas, or if slope angle restrictions are used.
Enable
Enables machining surface fillets with Pencil passes.
Number of stepovers
The number of stepovers defines how many offset passes in addition to the center curve of the fillets should be machined by the Pencil operation.
Machine steep with pencil
Machine steep with pencil allows to machine fillets on steep areas with Pencil passes. If it is selected, Contour and Parallel/Scallop passes leave bigger amount of stock inside surface fillets/internal corners. Afterwards Pencil passes machine those fillets accurately. This ensures better finishing of steep area fillets.
Slope Angle
Slope angle determines angle where switch between shallow and steep regions should be.
It is only available when "Scallop Closed" mode is selected as a Shallow strategy. It uses "Shallow angle" parameter from "Shallow" region for other modes. Pencil passes are generated only in shallow regions.
Direction
From the dropdown menu direction you can select in which directions Pencil passes are allowed to cut. You can choose between climb, conventional, both ways, down milling and up milling.
Climb milling means that the direction of the work piece relative to the tool is in the same direction as the tool rotation.
In conventional milling, the work piece motion relative to the tool is in the opposite direction of the tool rotation.
If both ways is selected the cuts will be carried out in both directions along the surface.
With the option down milling the tool will always move down hill along the geometry.
When up milling is selected the tool only moves up hill along the geometry.
Up / Down Shallow angle
The shallow angle is used to calculate the turning points of the surface when up milling or down milling are used. The shallow angle can be viewed as a tolerance of areas which should be considered flat such that the toolpath is not split up unnecessarily in almost flat areas.
Overthickness
The fillets in a geometry are found by virtually placing a ball mill on the geometry and detecting the areas in which the ball mill simultaneously touches the geometry at two points. The overthickness increases the diameter of this virtual tool, in order to detect fillets with a larger diameter than the tool diameter.
Bitangent angle
The fillets in a geometry are found by virtually placing a ball mill on the geometry and detecting the areas in which the ball mill simultaneously touches the geometry at two points. The bitangent angle defines the angle between those two touching points.

Rest material source
The dropdown menu rest material source lets you select the method for calculating the rest material to be removed by this operation. The following options are available:
Disabled: Defines that the current operation is not a rest machining operation. Choose this to carry out a regular operation.
Rest material operation: The rest material is calculated as the material left behind by one or more earlier operations. This is the most accurate method to use, as it works from where the tool actually went in the earlier operation, taking into account the space needed for lead in/out motions, as well as any other limitations of the earlier operations. This is also the only way to take more than one operation into account. Due to the increased precision, this method may take longer than other options to calculate. The operations which should be included in the rest material calculation are selected below.
Rest material STL file: The remaining material is calculated from a STL file, defining a pre-roughed or cast part, for example. The STL file must be specified below.
Rest material tool: Uses a theoretical tool to calculate the rest area, left by this tool, and uses it as basis for the rest material calculation. The theoretical tool is specified by its diameter and corner radius.
Rest material operation
Use the dropdown menu rest material operation to select the operation to be used as basis for the rest material calculation. Use the last of the operations if the result of more than one operation is to be used as basis.
Union of all dependent operations
Selecting the option union of all dependent operations will use the selected operation and any operations the selected operation depends on as basis for the rest material calculation.
Include all previous operations
Selecting the option include all dependent operations will use the selected operation and any operations above the selected operation in the operations manager as basis for the rest material calculation.
Only include operations within the same group
Selecting the option only include operations within the same group will use the selected operation and any operation above the selected operation which is in the same toolpath group as the selected operation.
Rest material STL file
Use the field rest material STL file to select the STL file to be used as basis for the rest material calculation. Right click to browse for a file or select it from a “recent files” list.
Adjustments
It is possible to adjust the rest material model for a better result:
Use as computed means no adjustment is used.
Ignore small cusps causes any areas of rest material smaller than the adjustment specified below to be ignored.
Adjustment
The adjustment is the size of the adjustment used when machine small cusps is used.
In the field on the right, all operations for the part created with HSM Performance Pack can be seen. The listing for each operation shows the operation type and the tool used, and can be expanded to also show the comment and stock to leave. The listings for each operation can be expanded or collapsed by clicking the plus or minus sign next to it. By right-clicking on an operation, it is also possible to view (but not change) all parameters for the operation, or expanding or collapsing all operations. When the rest material source is set to rest material operation, then it is possible to select the source operation by right-clicking it here and selecting Select. When the rest material source is set to Rest material tool, then it is possible to fill in the tool shape parameters by right-clicking an operation using the relevant tool, and selecting Fill-in tool parameters.

From the dropdown menu type the type of boundary can be selected. The available options are:
Contact
Machining
The available options for points are:
Entry
Home
Geometry source
From the dropdown menu Geometry source, the source of the geometry can be selected. The following options are available:
Use selected geometry
The option Use selected geometry generates the triangulation model for the toolpath generation from the selected geometry.
Use STL file
The option STL file lets you select an STL file which will be used for the toolpath generation. This can be particularly powerful when very large files are used, for which triangulation takes a long time. In this case a pre-generated STL file avoids lengthy re-calcuations. Note however, that it may be dangerous to use an external STL file since this will not automatically reflect any changes made to the CAD model.
Size
The field Size contains the file size of the STL file.
Date
The field Date contains the creation date of the STL file.
Path
Use the field Path to select the location of the STL file in your file system or define where the temporary STL file should be stored.
Geometry tolerance ratio
The Geometry tolerance ratio (%) defines the fraction of the operation tolerance (specified in the toolpath tab) used for generating the STL. The remainder is used for generating the toolpaths from the STL. This setting is ignored when using an external STL file. If the tool is very small, this value should be lowered to ensure that filets are represented correctly by the STL, and for complex parts, it is sometimes possible to reduce the calculation time by reducing this value.
Invalidate
The Invalidate button causes a new STL file to be recalculated at the next regeneration, regardless of the file policy setting.
Export
The Export button exports the current STL file to an external STL file for use in other programs or for comparison in verification.
Tool Containment
Use the radio buttons under tool containment to define the which part of the tool should be contained by the defined boundary. The following options are available:
Tool inside boundary
Using this option, the tool will be completely contained within the boundary.
Tool center on boundary
Using this option, the center of the tool will be contained by the boundary.
Tool outside boundary
Using this option, the tool may go over the boundary until the outside of the tool touches the boundary.
Additional offset
The additional offset defines an offset by which the previously defined tool containment is offset from the selected contour.
The fillets tab lets you apply toolpath fillets without the need to add these fillets to the CAD model.
|
Apply toolpath fillets
Apply toolpath fillets activates the toolpath filleting function. The toolpath filleting function modifies the toolpaths to prevent sharp corners in the toolpath by making the toolpath machine the area where a specified virtual tool would fit, instead of the machining surfaces. This causes fillets to be added at sharp corners and small radii.
Diameter
The diameter is the diameter of the virtual tool used to calculate the filleting.
Corner radius
The corner radius is the corner radius of the virtual tool used to calculate the filleting.
The toolpath tab contains various parameters which are needed to configure the toolpath and properly execute it on the CNC machine, such as arc filtering and other toolpath filters.
|
Arc filtering
The checkboxes under Arc filtering let you configure in which planes (XY-plane, XZ-plane, YZ-plane or helical arcs) arcs should be output to the machine as actual arcs (i.e. G2/G3), instead of being output as line segments (G1).
Minimum radius
The Minimum radius defines the radius below which an arc is output as line segments.
Maximum radius
The Maximum radius defines the radius above which an arc is output as line segments.
Minimum chord length
The Minimum chord length defines the arc chord length below which an arc is output as line segments.
Linearization tolerance
The Linearization tolerance is the tolerance used when arcs are to be converted to line segments, either because arcs are disallowed in that plane, or because the arc is too large or too small.
Arc fitting
Use the option Arc fitting to fit arcs where it is possible.
Maximum error
Defines the maximum error (distance) of the arc fitting to the geometry.
Filtering policy
Rapid filtering defines when rapid moves should be converted to linear moves (G1 in ISO code) at a high feed rate. The following filtering policies are available:
Preserve rapid movement: Rapid moves are always output as rapid moves (G0 in ISO code), even if they are in all three axes simultaneously. This option should only be selected if rapid moves on the machine are synchronized as linear moves.
Preserve Z-axis and XY-plane rapid movement: Rapid moves are output as rapid moves (G0 in ISO code) if they are along the Z axis or in the XY plane, but are converted to linear moves (G1 in ISO code) at a high feed rate if they are in all three axes.
Preserve vertical rapid movement: Rapid moves are output as rapid moves (G0 in ISO code) if they are vertical (i.e. along the Z axis), and are otherwise converted to linear moves (G1 in ISO code) at a high feed rate.
Preserve horizontal rapid movement: Rapid moves are output as rapid moves (G0 in ISO code) if they are horizontal (i.e. in the XY plane), and are otherwise converted to linear moves (G1 in ISO code) at a high feed rate.
Preserve one axis rapid movement: Rapid moves are output as rapid moves (G0 in ISO code) if they are in one axis only, and are otherwise converted to linear moves (G1 in ISO code) at a high feed rate.
Map to high feed cutting: All rapid moves are converted to linear
moves (G1 in ISO code) at a high feed rate.
High feed rate
High feed rate defines the feed rate used when rapid moves (G0 in ISO code) are converted to linear moves (G1 in ISO code).
Depth compensation
Depth compensation lets you choose in which way the toolpath should be vertically adjusted to the tool radius. The following options are available:
Tool center
The output toolpath corresponds to the path of the tool center.
Tool tip
The output toolpath corresponds to the path of the tool tip.
Miscellaneous
The Settings button opens up the Mastercam dialog for setting the miscellaneous values.
The operation tab lets you define important parameters for the execution of the toolpath on the machine. For example, here you can set the file name of the output NC file, define the working coordinate system, or configure the line numbering of the output file.
