In the mechanical processing process, the common methods of plate cutting include manual cutting, semi-automatic cutting machine cutting and CNC cutting machine cutting. Manual cutting is flexible and convenient, but the quality of manual cutting is poor, the dimensional error is large, the material waste is large, the subsequent processing workload is large, the working conditions are bad, and the production efficiency is low. The profile cutting machine in the semi-automatic cutting machine has a good quality of cutting the workpiece, and it is not suitable for single piece, small batch and large workpiece cutting because of the use of the cutting die. Other types of semi-automatic cutting machines, while reducing the labor intensity of workers, are simple in function and are only suitable for cutting parts of more regular shapes. Compared with manual and semi-automatic cutting methods, CNC cutting can effectively improve the cutting efficiency and cutting quality of the sheet and reduce the labor intensity of the operator. It is more common to use manual cutting and semi-automatic cutting in some SMEs in China and even in some large enterprises.
Block cutting machine has made great progress in cutting energy and numerical control control system. Cutting energy has been developed from single flame energy cutting to multiple energy cutting methods; CNC cutting machine control system has been composed of simple functions, complex programming and The input method and the degree of automation are not developed to have a perfect, intelligent, graphical, and networked control mode; the drive system is also driven from stepper drive and analog servo drive to today’s all-digital servo drive.
