What Machine Simulation Really Verifies?

Machine simulation verifies how your CNC machine will actually move, using real NC code, real kinematics, and real controller behavior.

This verification happens after postprocessing — where most CNC risks are introduced.

 

What Real NC Machine Simulation Detects — Before Machining?

Machine simulation focuses on machine-level risks that CAM toolpath simulation cannot detect..

 

Detect axis overtravel before the machine runs

Real NC simulation checks actual axis limits, rotary travel ranges, and machine envelopes — not just tool motion.

Catch collisions caused by machine kinematics

Collisions caused by rotary axes, head-table motion, fixtures, or machine structure are detected using real machine geometry.

Verify how the controller actually executes NC code

Machine simulation reflects controller-specific behavior

Reveal unexpected or unsafe machine movements

  • Even valid NC code can cause:
  • Sudden rotary flips
  • Unsafe retract paths

  • Non-intuitive axis combinations

What Is Actually Being Verified Here?

  • The simulation runs postprocessed NC code, exactly as it will be executed on the machine.

  • Machine motion, axis limits, and controller behavior are verified using real kinematics.

  • Any collision, overtravel, or unexpected movement is detected before machining starts.

 

Proven on Real CNC Machines

Machine simulation is applied on real production machines,
using real NC code — not demo or idealized setups.

“Every machine behaves differently. That difference is where CNC risks hide.”
