How to solve the problem of large error of CNC cutting machine?


After decades of development, CNC cutting machines have made great progress in both cutting energy and CNC control systems. The cutting energy has been developed from a single flame energy cutting to a variety of energy sources (flame, plasma, laser, high-pressure water jet) Cutting method, the degree of automation is not high and developed to have perfect functions.


The working principle of CNC cutting machine:

Usually, the CNC cutting system automatically processes the processed parts according to the pre-programmed processing program. We write the machining process route, process parameters, tool motion trajectory, displacement, cutting parameters and auxiliary functions of the parts into a machining program list according to the instruction code and program format specified by the CNC cutting system, and then put the content in the program list. It is recorded on the control medium, and then input into the numerical control device of the numerical control machine tool, thereby directing the machine tool to process the parts.


Since the CNC cutting equipment needs to process parts according to the program, after the programmer has compiled the program, it is input into the CNC system to direct the machine tool work. Program input comes through the control medium. In this way, the CNC system is used to control and complete the processing parts, and the graphics can be modified in time by the drawing staff, which can be used more freely, and the accuracy of the workpiece parts is also greatly improved than that of the semi-automatic cutting equipment!


How to avoid the error of CNC cutting machine:


The quality of the cutting nozzle of the CNC cutting machine will affect the surface quality of the workpiece and the flatness of the cutting side. The kerf compensation must be consistent with the actual kerf width. The way to reduce this kind of error is to choose a cutting nozzle with qualified quality. The specification of the cutting nozzle should also be suitable for the thickness and material of the plate to be cut. You can try to adjust the cutting on the waste first until the width of the cutting seam is uniform and the section is flat without slag. Cut a rectangle with a fixed length without compensation, and then measure it, and make up as much as the width of the kerf.
