In CNC machining, the post processor acts as a bridge between CAM software and CNC machines, converting toolpaths into machine-specific G-code. However, a notable reality is that the number of CNC post processor experts today is very limited, even among experienced engineers. Not only end users, but also CAM software resellers face challenges when customizing posts to meet customer requirements. So what makes this field so difficult to access, and what are the solutions?

1. Why are there so few CNC post processor experts worldwide?
1.1 Software programming knowledge requirements
To master post processors, users must not only understand CNC but also be proficient in the programming language used in CAM post editors. Most post processor editors today:
- Have complex structures
- Use logic similar to software programming
- Require a long learning curve
This creates a major barrier since most engineers are CNC specialists, not software programmers.
1.2 Each CAM is a separate ecosystem
Another major issue is that a post processor created in one CAM software usually cannot be used in another. This leads to:
- Time-consuming learning of multiple systems
- Inability to reuse knowledge
- Difficulty becoming a multi-platform expert
This is why many skilled users remain at the “basic editing” level.
1.3 Lack of structured training materials
Currently, learning resources for CNC post processors are fragmented, unsystematic, and difficult to access. Learners often have to self-study through scattered videos without a clear development roadmap. This makes the journey to becoming a CNC post processor expert long and inefficient.
1.4 Some CAM software does not allow post editing
Some CAM systems use closed environments that do not allow post processor editing. This means:
- No deep customization
- No opportunity for advanced learning
- Almost no chance to become an expert
1.5 Limited knowledge sharing in the community
Unlike other fields, post processor knowledge is rarely shared due to its proprietary nature. This limits the learning speed of newcomers.
