Research On The Control Of Machining Allowance Of Automobile Panel Die Casting

In an increasingly competitive market environment,modern manufacturing industry strives to maximize the benefits of rigorous and scientific manufacturing process quality management control,so as to reduce factory processing costs and improve the competitiveness of manufacturing enterprises.The stamping die for automobile cover parts is an important process equipment for automobile production.It uses its own special profile to perform drawing and post-engineering trimming,flanging,shaping and other processes.It uses various stamping equipment to process the steel sheet into the automobile outer cover.Products.The realistic demand of modern mold processing with high precision and high efficiency requires that the primary plane of mold castings have higher machining margin quality requirements when finished processing in the subcontracted company and stored in our factory.The main purpose of this research is to control the rough machining allowances within a certain range,to provide NC programming departments with conditions for program optimization,reduce machining losses,thereby improving machining efficiency,and at the same time avoid sharp changes in cutting load,so that the machine tool can Work in a steady state.Starting from the direction of quality control of the manufacturing process of automobile cover molds,the factors that cause the rough machining allowance of mold casting surface are analyzed,and the SPC(Statistical Process Control)technology is required to make the casting foam real shape,and make It becomes an important means to ensure that the solid surface processing is in a controllable state.During the period,the PDCA cycle is used to continuously optimize the production process.Through 5M1E to analyze the influencing factors of casting error,and set up corresponding improvement countermeasures.In addition,this paper also analyzes the influencing factors of the error during the first milling process of the mold.This article will carry out different experiments and investigations and adopt different countermeasures to ensure that each link of the production process is in a controllable quality,so that the rough machining allowance of the mold surface can meet the internal control requirements of the mold company.
