METHOD FOR MEASURING BACKLASH OF NARROW GROOVE MAKING MACHINE AND NARROW GROOVE MAKING MACHINE HAVING BACKLASH CORRECTING FUNCTION

摘要

PURPOSE: To provide a method by which the backlash of a narrow groove making machine provided with a backlash correcting function without adding any expensive device. ;CONSTITUTION: The title method consists of a process for making a narrow groove into a work 200, process for moving the narrow groove to the detecting position of a groove detecting means 23, process for stopping a moving table 22 after moving he table 22 by a first feeding amount (a), process for moving the narrow groove in the opposite direction to the detecting position of the groove detecting means 23 and detecting a second feeding amount (b), and process for calculating the difference between the fist and second feeding amounts (a) and (b).;COPYRIGHT: (C)1994,JPO&Japio
