CNC laser cutting machine is a large-scale equipment widely used in the manufacturing industry today. Due to the existence of vibration and deviation phenomena in the internal feed system, feed error cannot be avoided. If it is not compensated, it will affect the application effect of the cutting machine. Therefore, a high-performance CNC laser cutting machine feed error compensation method research is proposed. Thoroughly analyze the sources of feed errors in the cutting machine, determine the composition formula of feed errors (positioning error+force deformation error), clarify the measurement method of positioning error and force deformation error, obtain feed error data from multiple measurement points at the same time, use weighted average to calculate the final feed error to be compensated, and develop a feed error compensation program combining hardware and software equipment, By executing the established program, effective compensation for feed errors can be achieved. The experimental data shows that the feed error compensation results obtained by the proposed method are consistent with the expected feed position, and the minimum response time for feed error compensation is 0.1 seconds, fully confirming that the proposed method has stronger feed error compensation performance.
