PROBLEM TO BE SOLVED: To improve the machining accuracy and operation rate of an NC machine tool by allowing the tool tip coordinate position of a new tool to be set easily when a tool is changed. ;SOLUTION: Before a tool is changed, the blade tip position of an existing tool 7a is detected by a sensor, and a coordinate position at that time is stored. Next, the blade tip position of a new tool 7b is detected by a sensor and, as the coordinate position of the new tool 7b at that time, the coordinate position of the existing tool stored is set. Thus, when the new tool is positioned at the same blade tip position as that of the existing tool, the coordinate position becomes the same, and the machining of a new work can be started immediately after tool change.;COPYRIGHT: (C)1999,JPO
