Mitsubishi CNC Post Processor Development

Mitsubishi Electric CNCs are widely used by machine builders across Asia and beyond. Their G-code is FANUC-compatible in many areas, but high-speed and multi-axis functions need specific handling.

Mitsubishi CNC series

SeriesTypical use
M70 / M70VGeneral VMCs and lathes
M80 / M80VMid-range milling and turning, multi-axis options
M800 / M800VHigh-end machines, 5-axis and mill-turn

Functions a post should use

  • High-speed high-accuracy control (for example G05.1 Q1 or G05 P10000, depending on option) for 3D finishing.
  • Tool centre point control G43.4 / G43.5 for simultaneous 5-axis.
  • Inclined surface machining G68.2 for 3+2 work.
  • Extended work offsets G54.1 P...
  • User macros and subprograms (M98, G65) for probing and parametric routines.

The exact high-speed code and parameters depend on the options installed; always check the machine's parameter and option list.

Machine-builder differences

Machine builders using Mitsubishi CNCs add their own M-codes, tool changer logic and sometimes custom G-codes. We collect the builder's documentation and proven programs before configuring the post.

"FANUC-compatible" is a good start, but Mitsubishi posts still need Mitsubishi-specific tuning.
