AiVibePost-Processor
A post-processor is the CAM software component that converts neutral toolpath data into G-code formatted for one particular machine and control, including its codes, cycles, kinematics, limits and tool-change sequence.
CAM systems calculate toolpaths in a machine-independent form, often called cutter location data. The post-processor translates this into the exact program format a specific machine expects: block structure, G-code and M-code dialect, canned cycles, work offset calls, tool-change and safe retract sequences, coolant options and, for multi-axis machines, the transformation of tool orientations into rotary axis positions within the machine's travel limits.
Every machine and control combination needs a post-processor configured for it, because controls differ in syntax and machines differ in kinematics and options. CAM vendors and resellers supply post libraries and customise them for particular machines and shop standards, such as program headers, tool-list comments and probing calls.
An incorrect post-processor can produce code that looks plausible but rotates an axis the wrong way, retracts to an unsafe position or calls the wrong offset, so posts should be validated carefully when introduced or changed. Simulating the actual posted G-code against an accurate machine model catches many such errors before cutting. Posts should be kept under version control so that each released program can be traced to the post version that produced it.
Key points
- Converts machine-independent CAM toolpaths into machine-specific G-code
- Handles dialect, cycles, tool changes, retracts and multi-axis kinematics
- Each machine and control combination needs a configured post
- Validate posts with simulation of the posted code and keep them under version control
Where AiVibe comes in
AiVibe designs and manufactures the AiAmbA AI Factory: edge devices plus AI agents that let people talk to CNC, PLC and robot controllers in plain language. Agents only propose changes, and a trained operator confirms each one.
