CNC Post Processors
Accurate NC code, tailored to your machine, backed by engineers who know it
NC Code You Can Trust
A post processor is only as good as the code it produces. If the output doesn’t account for your machine’s exact kinematics, control syntax, and advanced capabilities, you’re leaving performance on the table — or worse, risking crashes and scrap.
Mastercam post processors are built differently. We develop them in direct collaboration with control manufacturers including FANUC, Siemens, and DMG MORI, so the output isn’t a best guess — it’s engineered to use your controller’s full feature set. The result is NC code that runs clean the first time, uses your machine the way its manufacturer intended, and doesn’t require hand-editing on the shop floor.
Industry-standard CNC Post Processing Solutions
Our post processors are developed in collaboration with leading control manufacturers — FANUC, Siemens, DMG MORI, and others. This isn’t just compatibility testing. Mastercam engineers work directly with control engineers to ensure the output takes full advantage of advanced cycles, high-speed settings, and axis configurations specific to each platform.
An extensive library of ready-to-run post processors and simulation environments supports the entire Mastercam product line: Mill, Lathe, Mill-Turn, Swiss, Router, and Wire. If your machine and control combination exists, chances are we already have a post for it.
When off-the-shelf posts aren’t enough, our engineering team builds custom solutions matched to your exact controls, kinematics, and production requirements. Following the acquisition of Postability — recognized for best-in-class post processing technology — Mastercam’s custom post development capability is stronger than ever, and accessible globally through your Mastercam representative.
Simulate what the machine will actually do — not just what you programmed
Most simulation shows you the toolpath. Mastercam’s post-driven simulation shows you the actual machine motion defined by the NC code output — so what you see on screen is what happens at the machine. If you change your post, the simulation reflects it automatically.
Catch travel limit violations, collisions, and finish quality issues before you waste machine time and material. Visualize full machine kinematics, including multi-axis positioning and tool changes, without leaving Mastercam.
