The most reliable source for post processors is the Autodesk software itself. During a standard PowerMill installation, the Autodesk Manufacturing Post Processor Utility (AMPPU) is installed automatically. This utility includes a collection of pre‑built post processors that are available as part of the installation and stored locally.
Document the specific machine model, control system version, and any custom modifications applied to each post processor. Include notes about what testing was performed and when the post processor was verified for production use.
A comprehensive PowerMill post processor customization tutorial covers the following key areas:
Preventing the machine from twisting wires or exceeding mechanical travel limits.
By securing a reliable and taking the necessary time to rigorously test and tweak its outputs, you unlock the true multi-axis efficiency of your CNC equipment—ensuring faster cycle times, superior surface finishes, and collision-free machining.
The best approach is to leverage the post processors included with PowerMill's installation, utilize the Autodesk Manufacturing Post Processor Utility for modifications and customization, and supplement with community‑shared resources when appropriate. Always prioritize safety by performing dry runs and verifying code on test parts before moving to production work.
Many users share post processors through various online platforms. While these can be useful starting points, exercise caution and always test thoroughly before production use.
The Autodesk forums are populated by expert users and Autodesk employees. Many users share their custom post processors here.
