Multi-path synchronization system for CNC controller

摘要

A single control unit in a multi-path synchronization system for a CNC controller simultaneously controls a plurality of paths. A program storage unit stores NC programs corresponding to respective paths. Those NC programs contains synchronization command codes which specify conditions of multi-path synchronization. A decoding unit decodes the NC programs for respective paths. Axis control unit controls the axes of a machine containing the paths by executing the decoded NC programs a in parallel. While executing the NC programs, synchronization control unit interlocks the motion of each axis according to the synchronization conditions specified by the synchronization command codes written in the NC programs.
