<p>PURPOSE:To provide a group control system for machine tool. equipments which can obtain the machining start coordinates of a machined object without measuring the coordinate previously. CONSTITUTION:A group controller 2 gets the name of the parts to be machined next and a process from the machining schedule data and takes a machining program and a measuring program out of the machining process data based on the machining parts name and the process. A numerically controlled tool machine 7 obtains an accurate machining start point ST based on the measuring target coordinates covering up to the machining start point ST of a machined object 29 set on the basis of a reference point SP2 corresponding to a reference point SP1 set on a table 27. Then the machine 7 sets again the coordinates as a new machining original point by adding the point ST to the reference point SP1. Furthermore the machine 7 obtains the accurate point ST based on the real machining start point coordinates covering up to the point ST of the object 29 set on the basis of the reference points SP2 corresponding to the reference point SP1 and sets again the coordinates as a new machining original point by adding the point ST to the reference point SP1.</p> |
