Abstract

PURPOSE:To improve accuracy of regulation and obtain uniform quality of works by shifting the target value of coarse regulation for succeeding material to be worked by the amount of change with the passage of time. CONSTITUTION:When a work is supplied, the initial characteristic value is measured by a characteristic measuring circuit and stored in a memory operating circuit and laser regulated to the target value of coarse regulation. An amount of regulation DELTAf5 is determined at this time and stored in the memory operating circuit. When regulation is made to the target value of coarse regulation, the work is carried once by a supply and carrying section, and supplied again for fine regualtion after the lapse of a specified time. At this time, the intermediate characteristic value fc after change by time is measured to determine an amount of intermediate change with the passage of time and fine regulation is performed. Proportional coefficient is determined from the amount of regulation and intermediate amount of change by time in the memory operating circuit and the amount of intermediate change by time is estimated. The target value of coarse regulation for the work is set each time, and characteristic value after intermediate change by time is made uniform.
