A post-processor converts the toolpaths displayed within your CAM system into NC code so you can run them on a specific CNC machine. When you create NC code, you need to choose the correct post-processor file for the CNC machine on which the program for cutting the part is to be run. Thankfully, there is a vast library of Post Processors available for the Autodesk CAM products.
Users of PowerMill can find installed Post Processors in the following folder:
C:\Users\Public\Documents\Autodesk\Manufacturing Post Processor Utility (version)\Generic
Users of FeatureCAM can find installed Post Processors in the following folder:
C:\Program Files\Autodesk\FeatureCAM (version)\Posts
Fusion 360 & Inventor CAM (HSM) users, you have access to the post library where you can run a search or filter by machine type and/or control.
