PURPOSE:To cut a work following a piercing operation and to improve productivity by comparing a distance between a working head and the work with a set value and controlling the working head so that it stops at a 1st set position and then at a 2nd set position in sequence. CONSTITUTION:Since the working head 1 can stop accurately at the 1st set position (a) and at the 2nd set position (b) and piercing and cutting of the work 4 following this piercing operation can be performed, the time between the piercing and the start of the cutting can be shortened drastically and consequently the productivity can be improved. |
