澳门新葡京线上官网 www.wxcsbsb.com Analysis of Ningbo metal processing detailed mechanical strength and modern design method
Process planning steps 1) calculation of annual production program, determine the productiontype. 2) analysis of parts and assembly graph, the process analysis to parts. 3) the choice of blank. 4) the drafting process route. 5) to determine the allowance of each working procedure,calculation of process dimension and tolerance. 6) determined by each process equipment andtools, fixtures, measuring tools and auxiliary tool. 7) determine the amount of cutting and man hour quota. 8) determine the technical requirements of the main process and test methods.Ningbo laser sheet metal processing 9) fill in the process documents. In the process of making process procedures, tend to the front has been preliminarily determined the contents of the adjustment, in order to improve the economic benefit. In the implementation process specification process, may appear before the material conditions, such as changes inproduction conditions, the introduction of new technology and new process, advanced equipment, new materials applications, require timely revised and includes the improvement ofmachining process on process specification: five axis machining, machining of ceramics,chemical machining, CNC machining, CNC milling, CNC machining, casting machining, micro machining, plastic machine, thread cutting, EDM, Swiss machining, electric spark line cuttingetc.. Machining equipment: lathe, milling machine, including machine, processing center, heavy duty machine, high speed milling machine and other machine tools, functional components.Machine processed products including: shaft, valve, shell, gear, turbine, fasteners, pipe, bar,metal bushing, turning parts of mechanical design manufacturing and automation, Nanjing University of Aeronautics & Astronautics, Shandong University, Dalian University of TechnologyWuhan University of Technology.
