These experimental features allow milling of four axis faces and pockets
These features are in early development. Bugs may exist. Thank you for your feedback and testing.
Installation
Ideally, upgrade to version 0.19.16502, or higher.
Download these scripts:
- PathProfileFaces.py available here and
- PathAreaOp.py is here
- PathPocketShape.py from here too (for pocket operations)
Place them in your FreeCAD/Mod/Path/PathScripts directory, *after* renaming your originals for safe keeping. Rename the new scripts to the original script names. Restart FreeCAD and have fun.
Use at your own risk.
Limitations
This feature does not handle complex rotations: those involving X and Y simultaneously.
There is currently no UI integration 4th-axis rotational settings in the release branch.
Usage
- Select the face(s) for the operation as normal
- Click on the Path Profile Faces icon to start the operation
- Change your settings as desired
- Click OK to run the operation
- In the properties list for the new operation, change the "Enable Rotation" setting as needed for the face(s)
- Recompute the operation
- Adjust start/final depths as needed. Final depth is coded to NOT go beyond the selected face used for the profile.
Trouble shooting
There is an "Inverse Angle" property. You may have to toggle this to get correct paths for some of your faces.
Set "Enable Rotation" to other than 'Off' to profile faces perpendicularly that are not normal to Z-axis.
Toggle the "Reverse Direction" property if the path appears to be off by 180 degrees.
