A post-processor (often called a "post" or ".pst" file) is a specialized program within Mastercam that acts as a translator. It takes the generic toolpath data generated by Mastercam—such as linear moves, arcs, drilling cycles, and tool changes—and converts it into the specific G-code dialect required by your CNC controller (e.g., Fanuc, Haas, Siemens, Heidenhain).

At its core, a post processor acts as a translator. It converts the generic toolpath data from Mastercam (Cutter Location Source data) into the specific G-code language that your unique CNC machine and its controller (like Fanuc, Siemens, or Heidenhain) can understand and execute safely.
