Abstract

The present invention relates to the field of laser processing, and in particular to a control method and system for improving the accuracy of laser dynamic cutting coil materials. The control method includes the steps of: setting the dimensional tolerance of the workpiece; The position error between the outer contour and the inner contour is compared with the dimensional tolerance; according to the comparison result, the compensation operation is used to selectively compensate the workpiece based on the processing path to eliminate the position error, and the outer contour of the workpiece that has been dynamically cut Measure the position error with the internal contour, and compare the position error with the dimensional tolerance, and then according to the comparison result, the machining path of the workpiece can be compensated to eliminate the position error. The control method measures the position error of the workpiece that has been dynamically cut, and selectively compensates the subsequent cutting according to the measurement result, thereby effectively reducing the compensation cost and improving user experience.

Description

technical field [0001] The invention relates to the field of industrial automatic production, in particular to a control method and system for improving the precision of laser dynamic cutting coil materials. Background technique [0002] Traditional laser processing is an intermittent and discontinuous processing mode. After processing a single sheet, it is necessary to exchange the worktable to replace the processed workpiece and the sheet to be processed. During this period, the laser head waits for cutting time, and the processing efficiency is low. In order to improve the processing efficiency, the coil can be processed directly. After the coil is uncoiled, leveled and straightened, it is transported to the laser equipment processing area for laser processing. [0003] China's authorized utility model patent CN201621017894.6 proposes an online laser cutting system for moving sheet metal. By setting the laser cutting machine on the slewing device and superimposing a coil ...
