To watch the condition of tools mounted on a turret punch press and an automatic tool changing unit, a control device performs a simulation of a punch processing on the basis of an NC program for the turret punch press. On the basis of the simulation, the control device calculate the number of times for which each tool mounted on the punch press performs punchings in the workpiece during the punch processing. From the number of times, the control device determine the abrasion loss of the tools mounted on the punch press and the automatic tool changing unit. The control device is also adapted to store a length by which a tool is shortened by a grinding processing to be made in a tool to sharpen the same.
