: Companies like Postability and ICAM partner with Mastercam to provide high-end, machine-specific post-processing technology. How to Install Downloaded Posts
Place your .MMD (Machine Definition) and .CONTROL (Control Definition) files into the ...\CNC_MACHINES\ folder.
When you program a part in Mastercam, the software generates an internal, generic file format known as an NCI (Numerical Control Intermediate) file. This file contains toolpath trajectories, feed rates, and speeds, but it is not machine-specific. The post processor reads this NCI data and translates it into the precise G-code and M-code language that your specific machine tool controller understands. Mastercam Post Processors Download
: For unique machine/control combinations, users can download and submit specific Post Request Forms (e.g., Mill, Lathe, or Router forms) to their local Mastercam Reseller to receive a customized solution. Common Delivery Formats
The Control Definition file. This dictates how G-code formatting looks (e.g., whether to use sequence numbers, how many decimal places to output, and arc configurations). Post Engines (MP vs. MPST)

Always create a backup copy of your original, working post processor files before opening them in a text editor like Mastercam Code Expert or Notepad++. Change only one variable or code block at a time, post a sample toolpath, and use a text-compare tool to verify exactly how your changes altered the resulting G-code.

Mastercam is a popular computer-aided manufacturing (CAM) software used by machinists and manufacturers to create precise toolpaths and G-code for CNC machines. One of the essential components of Mastercam is the post processor, which plays a crucial role in converting the toolpath data into a format that can be understood by the CNC machine. In this article, we will discuss Mastercam post processors, their importance, and provide a step-by-step guide on how to download and install them.
