Siemens 828d Post Processor For Mastercam: ^hot^
The Siemens SINUMERIK 828D is a compact, panel-based CNC controller widely used in turning and milling centers (such as DMG MORI, EMCO, and generic machine tools). Known for its "ShopMill" and "ShopTurn" conversational programming interfaces, it also excels in running ISO G-code generated by CAM systems like Mastercam.
However, Mastercam users don't want to program at the control. They want to use dynamic motion, OptiRough, and 3D high-speed toolpaths.
Unlike standard ISO/Fanuc controls, the Siemens 828D excels when using its native cycle language. Ensure your post processor file ( ) is configured to support the following parameters: High-Speed Machining (CYCLE832): siemens 828d post processor for mastercam

For 828D swivel heads or rotary tables, the post must output TRAORI (activate TCPM) and TRAFOOF. Additionally, mill-turn posts require TRANSMIT for cylindrical mapping. Mastercam’s Generic Fanuc 5X Mill.pst cannot handle this—you need a Siemens-specific 5-axis post that processes M128 (Siemens’ TCPM code).
The Production Turning Center: "The 828D on our lathe wants ShopTurn cycles. Our old post output long G-code. The new post outputs CYCLE95 for stock removal and CYCLE93 for grooves. The machine runs smoother, and the control screen shows graphical previews of each cycle. It’s a game-changer for our operators." Do not attempt to write a Siemens post
The Siemens 828D is a popular CNC (Computer Numerical Control) system used in various industries, including aerospace, automotive, and mold making. Mastercam is a widely-used CAD/CAM (Computer-Aided Design/Computer-Aided Manufacturing) software that provides a comprehensive suite of tools for designing and manufacturing parts. A post processor is a critical component that enables Mastercam to communicate with the CNC system, converting the CAM software's output into a format that the CNC machine can understand. This report focuses on the Siemens 828D post processor for Mastercam.
