Most CAM software accomplishes this with an intermediate format called " CL.Data." Post Processors (usually do not convert g-code from one dialect to the next), rather the “post” uses an intermediate format that captures the G-code commands in a dialect-independent form. Post processor is a software subroutine(sub-program) which converts graphical or non-graphical CAM software toolpath outcome into a specific NC Control(Fanuc, Sinumeric, Mazatrol, Heidenhein) Deckel-Maho etc). #Feature cam post process for mach 3 software
#Feature cam post process for mach 3 software. Testers needed - any feedback appreciated. Should there be interest I will make a version that has the 4th axis parallel to machine X. The only version currently available is for machine that has the 4th axis along Y. Files in the /old directory are kept just for reference. Is a completely new implementation of the post, that uses SolidCam's new kinematics (pos_to_machine=Y). Usage : Do set your CoordSyses so that the CS origin is on the pivot point (axis of rotation) and X/Y is the axis around which the part revolves PostDevTestMachine I recall having issues with 360 wrap around so check by cutting air before destroying an important part. Config > Toolpath - Check Y-axis for axis of rotation and enable A-rotations. Config > General Config - tick A-axis is angular, set IJ mode to incremental, uncheck all in Rotational, possibly also check G04 dwell in ms. Usage in SolidCam - Select Mach3_4X_Y for CNC-Machine. You need to restart SolidWorks for it to pick up the new files. vmid files in C:\Users\Public\Documents\SolidCAM\SolidCAMXXXX\Gpptool. As of now it's safe but can be made faster w/o retracts. 4x indexial use may need some more work to avoid unnecessary retracts to clearance. Drill cycles - G81 (drill), G82 (drill+dwell), G83 (peck drilling), Canned cycles: G85 (boring), G86 (bore and stop), G89 (in, dwell, out). 4 axis - working / for both repositioning moves and 4x toolpaths. Here's a video of a part being cut with code generated by this post :
