Application Analysis of CNC Cutting Technology in Railway Freights Car Products
Improving the utilization rate of sheet metal was one of the important indicators of the technical level and management level of enterprises,and it was also a key measure to reduce manufacturing costs.In major products such as railway freights,about 70％of the components were stamped parts,so the rational use of plates was crucial to reduce the cost of vehicle manufacturing.In order to achieve the goal of energy saving and cost reduction,it was necessary to improve the utilization rate of sheet metal through scientific and reasonable cutting and applying a variety of cutting processes.Through the research of the factors affecting the material utilization rate in the cutting process,the traditional cutting tech-nology was improved,and with the help of computer aided design,a set of ways and methods to improve the material utili-zation rate were summarized,and the field practical application was carried out,and obvious economic benefits were ob-tained,which had certain reference significance for railway freight car enterprises.
