A typical post processor for Mastercam 2023 includes several critical components:
sgcode : "G" # String for G-code sgrp1 : "G" # Group 1 (Modal) # Custom code for high-pressure coolant scoolant_hp : "M88" # High pressure on
A standard Mastercam post consists of three primary files: the Machine Definition Control Definition 10 Mastercam 2023 Features You Need to Know post processor mastercam 2023
Mastercam 2023 did not introduce a ground-up rewrite of the post engine, but it delivered significant enhancements that directly impact post customization.
Since Mastercam 2023 utilizes a more integrated "Mastercam Machine" environment, the connection between these three files is tighter than ever. A typical post processor for Mastercam 2023 includes
His current war was with an ancient Okuma LB3000 lathe, affectionately nicknamed "The Beast." The machine was from 2008, with a controller that had more quirks than a conspiracy theorist. It demanded G13 for live tooling approach, rejected standard G70 finishing cycles, and threw a hissy fit if it saw a decimal point in a feed rate. The generic post processor that came with Mastercam 2023 worked beautifully for Haas and Mazak, but on The Beast, it was a suicide note in text form.
A post processor is a text-based configuration file that translates the generic NCI (Numerical Control Interface) data generated by Mastercam into machine-specific G-code. Think of Mastercam as a universal translator for human languages; the NCI is the universal language, and the post processor is the dialect dictionary for a specific CNC control (e.g., Haas, Siemens, Heidenhain, Fanuc, Okuma). It demanded G13 for live tooling approach, rejected
For Mastercam 2023, pay attention to arcoutput$ . Many newer controls prefer (radius) over I,J,K vectors to reduce code size, but older controls require IJK for plane accuracy.
