It’s Time to Rethink CNC Post-Processing
For more than four decades, one of the most critical elements in CNC manufacturing — CNC post-processor — has remained locked away behind complexity, secrecy, and outdated practices.
It’s a silent bottleneck affecting productivity across the global manufacturing industry. And yet, most CAM software companies continue to overlook it. Why? Because true change would mean giving users more control — and that challenges the old business model.
At MANUS, we believe it’s time to challenge that status quo.
While developing MANUSpost Developer, we asked ourselves one key question: What would CNC post-processing look like if it were open, accessible, and designed for today’s engineers — not the programmers of 1980?
From that question, a set of principles emerged — our CNC Post-Processor Manifesto.
🔧 1. CNC post-processing should not remain a black box.
It should be open, teachable, and accessible to everyone who wants to understand and improve it.
🔧 2. You don’t need to be a software developer to create or edit a post-processor.
Technical knowledge and curiosity should be enough — not years of coding experience.
🔧 3. One post, multiple CAM systems.
A reusable post-processor should work across platforms. No one should start from zero just because they changed CAM software.
🔧 4. Editing a post should be intuitive.
Making a change shouldn’t feel like decoding ancient scripts — it should be as simple as adjusting a setting.
🔧 5. Knowledge should be shared.
An open, community-driven post library should exist, where solutions to common problems are accessible to all.
🔧 6. Post-processors hold real value.
They shouldn’t be free, nor overpriced — but fairly accessible, reflecting the real work and expertise behind them.
🔧 7. Freedom from forced upgrades.
No one should be pushed to change their entire CAM system just to make a small post modification.
🔧 8. Simulation must be part of the process.
Every change made to a post should be verifiable through reliable CNC simulation — easily and safely.
🔧 9. Education should evolve.
Universities and technical schools should go beyond basic G-code training and include post-processor fundamentals in their CNC curriculum.
🔧 10. Post-processors should evolve continuously.
They’re not static files — they’re living components of the CNC workflow that should grow as machines and strategies advance.
A Call for Change
This isn’t just a technical issue — it’s about democratizing CNC manufacturing. For too long, post-processing has been hidden behind proprietary walls, cryptic code, and vendor dependence. That era is ending.
With MANUSpost Developer, we’re building a more open, flexible, and user-driven future for CNC post-processing — one where engineers have true control over their tools.
