CNC Post Processors

CNC Post Processor Development Without Production Machine Access

Production machines are expensive to stop. Most post processor development can be done remotely, with machine time needed only for a short final proving session.

What we need instead of the machine

  • Machine builder, model, controller model and software version.
  • Controller options list (TCP, tilted plane, high-speed mode, probing, cycles).
  • Axis travels, rotary limits and kinematic dimensions (pivot distances).
  • MTB M-code list and tool changer details.
  • Proven sample programs that already run on the machine.
  • Photos or videos of the machine, work-holding and a typical setup.

Digital twin and simulation

We build or use an accurate machine model in the CAM system or a dedicated simulator. The posted G-code is simulated against the model, checking travel limits, rotary solutions and collisions with the head, table and fixtures.

Using sample programs

(A proven program from the machine shows us:)
(- exact header and safe start the machine expects)
(- tool change sequence and M-codes)
(- how TCP / tilted plane is called)
(- cycle formats that work on this controller)

Remote proving support

During the proving session, the operator runs the program while we join by video call or screen share, reviewing each critical block and fixing issues on the spot.

With good data and simulation, machine downtime for post development can be reduced to a few hours.
