Abstract
A method for controlling a seat of an optical lens on a laser processing machine comprising the following steps: a. the optical laser lens-seat divides the working zone into three parts when it is moved over the working piece; b. the optical laser lens-seat is accelerated when it stays at the first part, is in a constant speed when it stays at the second part, and is decelerated when it stays at the third part; c. the optical laser lens-seat keeps its normal output power when it is at the part with said constant-speed, its output power is relatively increased when it is at the part being accelerated, and its output power is relatively reduced when it is at the part being decelerated; d. the amount of laser irradiation in each displacement unit thus is equal, both sides of the working piece do not need to leave inactive sides, hence working time is reduced.
