METHOD FOR DETECTING THE PRESENCE OF A CHARACTERISTIC OF A WORKPIECE FOR MACHINING AND CONTROLLING THE EXECUTION SEQUENCE OF A MACHINING PROGRAM

摘要

The invention relates to the numerical control of machine tools. A machining program intended to control a relative movement between a tool carrier 15 and a workpiece 14 comprises, in particular, the first instructions. UNDER WHICH A DETECTION ELEMENT 16 EXECUTS AN EXPLORATION CYCLE TO DETECT A CHARACTERISTIC OF THE PART AND SECOND INSTRUCTIONS THAT DETERMINE THE FOLLOWING OPERATIONAL STEP TO BE EXECUTED, BASED ON THE RESULT OF THE DETECTION. THE FOLLOWING OPERATING STEP MAY BE PLACED IN SEQUENCE IN THE PROGRAM OR MAY BE IDENTIFIED BY THIRD INSTRUCTIONS THAT DEFINE A NON-SEQUENTIAL PROGRAM LOCATION. / P P APPLICATION TO AUTOMATIC MACHINING OPERATIONS. / P
