ABSTRACT:
A control apparatus which increases a hit rate, stabilizes a punch process, and makes use of a small motor. Such control apparatus is applicable to a punch drive apparatus that drives a punch tool by a servomotor via a ram and a toggle system. Such a structural arrangement includes a memory that memorizes a ram speed curve line from when the servomotor starts rotating to when the ram achieves a fixed speed; another memory that memorizes a surface height position of a sheet metal; and calculating device that calculates the lowest height of the ram at the aforementioned fixed speed when the punch tool reaches the surface of the sheet metal, and then sets a raised stand-by position of the ram. Such raised stand-by position is set in a ram shaft control device having the servo-controller.
