Why Toolpath Simulation Is Not Enough
Most CNC failures happen after postprocessing — not in CAM.
Toolpath looks safe, NC code is not
Standard CAM simulation does not account for
real controller behavior, axis limits, or kinematics.
Postprocessor behavior is machine-specific
The same NC code can behave differently
on different machines — even with the same controller.
Most crashes happen after postprocessing
Collisions and overtravel issues are often discovered
only when the NC code runs on the machine.
Reducing CNC Risks — Before the Machine Runs
The highest CNC risks occur after postprocessing and before machining. This stage can only be verified by simulating the actual NC code on the real machine model.
Verify NC Code on the Real Machine — Before Machining
NC code is verified against the actual machine — not just the toolpath.
Collisions, overtravel, and unexpected motion are detected early, before any material is cut.
Engineering-Driven Postprocessor Development
Custom NX CAM postprocessors validated through real NC machine simulation — not assumptions.
How OptiTech Builds and Verifies NX CAM Postprocessors
- Postprocessors are developed together with real machine kinematics and controller logic, not as generic NC output templates.
- Every NC program is verified using real NC machine simulation, ensuring axis motion, limits, and machine behavior are correct after postprocessing.
- Post and simulation work as one validation process, catching collisions, overtravel, and unexpected motion before production.

Frequently Asked Questions
Everything you need to know about NX CAM Postprocessors and Machine Simulation.
What is a CNC postprocessor?
A postprocessor converts CAM toolpaths into machine-specific NC code. A properly developed postprocessor ensures your CNC machine receives accurate instructions based on its controller, kinematics, and machining requirements.
Why shouldn't I use a generic postprocessor?
Generic postprocessors are designed for basic applications and often require manual editing. OptiTech develops machine-specific postprocessors tailored to your CNC machine, controller, and production workflow, reducing programming errors and improving reliability.
Does OptiTech provide Machine Simulation?
Yes. We provide Real NC Machine Simulation, allowing you to validate the actual NC code on the machine’s digital twin before machining. This helps detect collisions, overtravel, and unexpected machine movements before production.
Can I try a postprocessor before purchasing?
Yes. For many CNC machine models, OptiTech offers a trial program, allowing customers to evaluate the postprocessor on their own machine before making an investment.
How long does postprocessor implementation take?
Implementation time depends on the machine configuration and project requirements. For many popular CNC machines already available in our library, deployment can be completed significantly faster than developing a postprocessor from scratch.
Do you support 3+2, 4+1, and 5-axis CNC machines?
Yes. OptiTech develops postprocessors for 3+2, 4+1, and full 5-axis CNC machines, including rotary table and trunnion configurations. We also support machines without TCP (Tool Center Point) or TWP (Tilted Work Plane) functions.
