Abstract
The present application relates to the technical field of laser cutting, and specifically relates to a method for capacitive compensation of a laser cutting system for environmental temperature change. The method comprises the following steps: 1) initializing the position of a laser cutting head, placing the laser cutting head in a temperature box, collecting multiple sets of temperature values and corresponding capacitive values by changing the temperature, and obtaining a temperature value-capacitive value relationship curve; 2) testing the temperature value-capacitive value relationship curve by changing different conditions; 3) calculating the slope of the temperature value-capacitive value relationship curve in different temperature intervals; 4) performing capacitive calibration in a conventional environment and recording the temperature value at the time of calibration; and 5) compensating the capacitive value by using the slope of the relationship curve and the calibration temperature value when the temperature changes. The present application solves the problem of capacitive value increase or decrease caused by environmental temperature change through capacitive compensation, ensures that the cutting head maintains a stable height when following the cutting, and thus achieves the expected cutting effect.
