Post processor
A post processor, also known simply as a post, is a computer program which converts tool path data from CNC software into machine tool data, to be used in CAM systems.[1][2] A post processor generates the G-code used by the machine control module.[3] The generated code will differ for each G-code dialect the post-processor supports, and will often be customized to match the limitations of the machine.[4] Post processors can be either open- or closed-source software; closed-source posts are usually created by CAM vendors, while open-source ones are made by the community or home users.[5][6] It can be difficult, however, to custom-write post-processors, as the code syntax used by the machine often varies; several efforts have been made to create a standard language.[1]
Post-processors can be generic (being programmed for one machine) machine-specific, or custom-built.[7] Post processors can also be used to auto-create pocket routines or, in specific cases, run robots using G-code instructions.[5]
