The Study On CNC Machining Processing Technology Of Automotive Panels

Automotive panel die is the important process equipment for auto body manufacture,so the manufacturing of automotive panel die is the key link of auto body manufacture.Due to the advanced CNC machining technology,CNC machine tools have become the key mold manufacturing equipment of automotive panel die,different from the traditional mechanical processing,CNC machine tool operation and processing program has certain complexity and difficulty,it also put forward higher requirements of comprehensive quality and machine operators operating level processed the automotive panel die.At present,our company is limited by the staff's lack of experience in operation,programming,processing experience,and so on,so that the efficiency and quality of NC machining of automobile panel dies can not be guaranteed.Therefore,it is urgent to carry out the research on NC machining technology of automotive panel dies.First of all,combined with the current automotive panel die processing research and domestic mainstream manufacturers related to the processing and manufacturing status,taking into account the requirements of the line and the actual processing equipment,staff experience and other aspects of proficiency,and further clarify the automotive panel die CNC machining process the significance of the study.Different automotive panel dies of its numerical control processing technology design differences,analysis of the existing literature research results,developed a perfect and standard automotive panel die CNC machining process specifications,programming norms,process parameters selection specification is not only to improve the automotive panel die CNC machining efficiency and processing quality of the necessary conditions,or to achieve the modernization of the panel die CNC machining the only way.Secondly,the paper analyzes the characteristics and process requirements of automotive panel and automotive panel die,analyzes the tool selection of rough,finishing process of automobile cover,the selection of processing technology parameters and the selection of cutting way.Combined with the research and analysis of a typical drawing die of a car panel and the actual manufacturing process,we develop an appropriate process parameters,programming,etc.to the company's automotive panel die CNC machining process according to the actual situation of our company.In order to use the regulation to select the norms of our company's automotive panel die CNC machining efficient,energy saving,reliable and other new ideas.Finally,the practice has proved that the implementation of automotive panel die CNC machining process selection,process parameters and processing procedures for the standardization of standardization is to improve our company's automotive panel CNC machining efficiency and processing quality of an effective way.The relevant specifications of CNC machining of automotive panel die s need to be further improved in the follow-up manufacturing process,making it more instructive.
