Post processor

A Post Processor is a unique “driver” specific to a CNC machine; some CNC machines start at different locations or require extra movement between each operation, the Post-Processor works with the CAM software to make sure the G-Code output is correct for a specific machine build. Another example of use for a Post-Processor would be an ATC (Automatic-Tool-Change) for a CNC, the Post-Processor is required so the correct Tool is collected from the correct location. The Post Processor controls the format and syntax of the program that is generated for the controller that controls a specific machine (typically a CNC or a robot).

A post processor is commonly used by the CAM (Computer Aided Manufacturing) Software to generate G-code for a specific CNC Machine.
