The Challenge
John, a CNC programmer at a job shop, was working on a project that required him to machine complex parts on a Siemens-controlled mill. The shop had recently purchased a new mill with a Siemens 828D control, and John needed to post-process his Mastercam files to generate G-code that the new mill could understand.
However, the standard post processor for Mastercam didn't quite work with the 828D control. The shop's older mills used a different control, and the standard post processor was not compatible with the new mill. John tried using the existing post processor, but it resulted in incorrect G-code that caused the mill to malfunction.
The Solution
John decided to create a custom post processor for Mastercam that would work specifically with the Siemens 828D control. He started by researching online and consulting the Siemens 828D programming manual to understand the specific requirements for G-code on that control.
Next, John used Mastercam's post processor editor to create a new post processor from scratch. He carefully defined the output settings, such as the G-code dialect, coordinate system, and canned cycles, to match the requirements of the 828D control.
The process was not without its challenges, however. John encountered several issues while testing the new post processor, including incorrect output of G-code for certain machining operations. He had to carefully review the post processor code and make adjustments to get it working correctly.
The Outcome
After several days of work, John finally had a working post processor for Mastercam that generated correct G-code for the Siemens 828D control. He tested it on several parts, and the results were excellent. The mill ran smoothly, and the parts were machined accurately.
The custom post processor not only solved the immediate problem but also opened up new possibilities for the shop. John could now confidently program and machine complex parts on the new mill, taking advantage of its advanced capabilities.
The Benefit
The shop's investment in the new mill with the Siemens 828D control was now paying off. John could produce high-quality parts more efficiently, and the shop could take on more complex projects. The custom post processor had eliminated a major hurdle, allowing the shop to maximize its use of the new mill.
From that day on, John was known as the "post processor guru" in the shop, and his expertise was sought after by other programmers. He continued to refine and improve the post processor, ensuring that it remained compatible with future updates to Mastercam and the Siemens 828D control.

You have three routes:
Developing a post for Mastercam to the 828D requires attention to several critical areas:
The rough machining was working, but the finish was messy. The program header was cluttered with useless comments, and the tool changes were clumsy. The Siemens 828D has a beautiful interface, and I wanted the code to look professional.
I customized the header to print the program name, date, and material using Siemens system variables.
Instead of:
; Program: Part_1
I wrote the post to output:
MSG("Program: Part_1 - Running...")
This displayed the program name on the operator's screen in real-time.
Next was the tool change. The generic post used T1 M6. The Siemens turning center preferred T1 D1. I had to hunt down the tool change strings and rewrite the formatting logic to handle the D-offset (Tool Offset) automatically.
In the world of CNC machining, the toolpath is only half the battle. The other half is translation—converting the generic motion of CAM software into machine-specific, readable code. For shops operating Siemens 828D controllers with Mastercam, the Post Processor is the critical linchpin. Without a properly configured post, even a perfectly programmed part can result in collisions, alarm states, or surface finish errors.
This article explores the architecture, customization, and best practices for developing or fine-tuning a Siemens 828D post processor for Mastercam.
A Siemens 828D post processor for Mastercam is not a "set it and forget it" tool. It requires deliberate configuration of cycles, R-parameters, tool naming, and subprogram syntax. Whether you choose to build, buy, or modify, rigorous testing in simulation and on-machine dry runs is non-negotiable.
When done right, the post becomes invisible—translating Mastercam’s toolpaths into flawless 828D code, cycle after cycle. When done wrong, it becomes the most expensive bottleneck in your shop. Invest the time upfront, or invest the money in a proven solution.

The Story of the "Incompatible Soul": Building a Siemens 828D Post Processor for Mastercam
The setting is a typical job shop on a rainy Tuesday. The smell of coolant hangs heavy in the air, mixing with the sharp tang of freshly cut steel. I stood in front of the controller of a brand-new Siemens Sinumerik 828D turning center. It was a beautiful machine—rigid, fast, and intelligent.
On my workbench sat a laptop running Mastercam 2024. The CAD model was pristine, the toolpaths were optimized, and the simulation looked like a symphony of metal removal. There was just one problem: the language barrier.
Mastercam spoke a dialect of generic G-code, and the Siemens 828D spoke a sophisticated, high-level dialect that might as well have been Martian. I clicked "Post" and watched the scrolling text. I transferred the file to the machine, hit Cycle Start, and was immediately greeted by an angry red alarm on the Siemens HMI: "Syntax Error in Line 12."
That was the beginning of a two-week journey into the heart of the Siemens 828D post processor. It’s a story familiar to every CNC programmer and manufacturing engineer. Here is the detailed account of that journey.
Before editing the post processor, the developer must identify the machine configuration:
