Abstract

PURPOSE: To index accurate length of a tool and automatically perform offset of the tool, by contacting the tool of an NC lathe at low speed to a contact switch.
CONSTITUTION: A machine zero point 9 is set to a point on the main spindle axial line 11 of a lathe. When length of a tool is measured, a tool slide is quickly traversed toward a contact machine 4 and switched to a traverse at fine speed by allowing a photoelectric switch 6 to detect the contact of a tool end to the position of a point 1. If the tool end is contacted to the contact detector switch 4, the traverse of the tool slide is stopped to calculate a tool length 16 from distances 14, 15. When the tool length is calculated to set a tool offset amount, the tool slide is performed turning indexing.
