Description
The Adaptive tool uses an adaptive algorithm to create clearing and profiling paths that manage cutter engagement so that engagement and material removal never exceed a maximum value.
Usage
Usage instructions for the Adaptive operation are presented here.
Basic Operation
- Press the Adaptive icon, or select the Path → Adaptive from the top menu.
- Select the tool controller for the Operation from the Tool controller dialogue pop up window, if prompted.
- Adjust the operation depths as needed in the Depths tab: Start Depth, Finish Depth, Step Down.
- Make adjustments in Heights tab if needed.
- Configure settings in the Operations tab:
- (See the Properties → Adaptive section below.)
- Set the Step Over value as a percentage of the diameter of the Tool.
- If you wish to preview the result before accepting the settings, click Apply
- Click OK button to confirm and generate paths.
Preliminary Notes About Adaptive Clearing
- Depending on the size and complexity of the area for the operation, is might be better to not recompute the operation after every property change; rather, consider:
- The Adaptive operation might contain a few bugs yet to be clearly identified. Please report bugs and issues in the FreeCAD Path/CAM Forum.
- All tool shapes may not be respected with this operation. Check the FreeCAD forum for further details.
- Should you choose to run the path simulator in the Path Workbench, it only uses the standard end mill to simulate paths. Therefore, you will not see tool-shape-specific material removal. Material removal is shown using the end mill shape.
Properties
Note : The names of some Properties in this list differ a little from the same settings used in the Task Window Editor.
Adaptive
- DANEForce Inside-Out: Force plunging into material inside and clearing towards the edges
- DANEHelix Angle: Helix ramp entry angle (degrees)
- DANEHelix Cone Angle: Angle (degrees) of conical helix
- DANEHelix Diameter Limit: Limit helix entry diameter, if limit larger than tool diameter or 0, tool diameter is used
- DANEKeep Tool Down Ratio: Max length of keep tool down path compared to direct distance between points
- DANELift Distance: Lift distance for rapid moves
- DANEOperation Type: Type of adaptive operation: Clearing or Profiling
- DANESide: Side of selected faces that tool should cut: Inside or Outside
- DANEStep Over: Percent of cutter diameter to step over on each pass
- DANEStock to Leave: How much stock to leave (i.e. for a separate finishing operation)
- DANETolerance: Influences accuracy and performance
- DANEUse Helix Arcs: Use Arcs (G2) for helix ramp
Base
Note: It is suggested that you do not edit the Placement property of path operations. Rather, move or rotate the Path Job model as needed.
- DANEPlacement: Overall placement[position and rotation] of the object - with respect to the origin (or origin of parent object container)
- DANEAngle: Angle in degrees applied to rotation of the object around Axis property value
- DANEAxis: Axis (one or multiple) around which to rotate the object, set in sub-properties: X, Y, Z
- DANEX: X axis value
- DANEY: Y axis value
- DANEZ: Z axis value
- DANEPosition: Position of the object, set in sub-properties: X, Y, Z - with respect to the origin (or origin of parent object container)
- DANEX: X distance value
- DANEY: Y distance value
- DANEZ: Z distance value
- DANELabel: User-provided name of the object (UTF-8)
Depth
- DANEClearance Height: The height needed to clear clamps and obstructions
- DANEFinal Depth: Final Depth of Tool- lowest value in Z
- DANEFinish Depth: Maximum material removed on final pass.
- DANESafe Height: The above which Rapid motions are allowed.
- DANEStart Depth: Starting Depth of Tool- first cut depth in Z
- DANEStep Down: Incremental Step Down of Tool
Path
- DANEActive: Make False, to prevent operation from generating code
- DANEComment: An optional comment for this Operation
- DANETool Controller: Defines the Tool controller used in the Operation
- DANEUser Label: User assigned label
Tasks Window Editor Layout
Descriptions for these settings are provided in the Properties list above.
This section is simply a layout map of the settings in the window editor for the Operation.
Base Geometry
- Add: Adds selected element(s) which should be the base(s) for the path(s).
- Delete: Delete the selected item(s) in the Base Geometry list.
- Clear: Clear all items in the Base Geometry list.
Depths
- DANEStart Depth
- DANEFinal Depth
- DANEFinish Depth
- DANEStep Down
Heights
- DANESafe Height
- DANEClearance Height
Operation
- DANETool Controller
- DANECut Region (Side)
- DANEOperation Type
- DANEStep Over Percent
- DANEAccuracy vs Performance (Tolerance)

Known Issues
In case Path Adaptive creates some unwanted paths, try with a DANEStock to Leave set to 0.001 mm
or more. You can reduce the diameter of the tool by double that amount to keep the paths exact.
A proposed bugfix is available (but no one is working on integrating it):
