Abstract
A method for controlling a cutting tool in a CNC machine and a device using the method receives contours of workpieces generated by a first measuring machine, inputs the first contour parameters into a calculation model to output first compensation values of the cutting tool, the calculation model being a time sequences model established according to contour sets of the workpieces, and the contour sets include at least one historical contour of the workpieces. The device further determines whether the first compensation values of the cutting tool are greater than, equal to or smaller than a preset value, and sends the first compensation values of the cutting tool to a machine.
