Abstract
One of the main features of CNC machining is a precision machining and high efficiency. CNC machining products, excellent quality parts consistency , productivity and machining accuracy is higher than a lot of general machine tools , when machining complex surfaces , contours and curves of irregular or precision requirements for processing complex multi- process product its technology advantage is unmatched by ordinary machines . Jigs and fixtures are an important part of mechanical engineering, is the basis for machining, is also a subject of technical equipment. Workpiece positioning and clamping fixture, directly affect the success or failure of the workpiece machining and processing quality. Design Methods and jig fixture determines the ease of machining and processing efficiency. If we say that we must rely on metal machining machine tools, then clamp equipment is improved machining accuracy, reduce labor intensity, reduce processing time, reduce workers' technical requirements, production automation technology and equipment is indispensable. Process planning is based on the actual processing conditions and processing parts of the specific circumstances, to develop a rational process route and process documents in accordance with the form prescribed making. Machining process is an important technical documents machinery factory production management, the impact of parts processing quality, productivity and cost, the size of manufacturing capacity, production batch size and processing techniques to handle different measures and methods must also use the process of order to show . Analyze and determine the correct routing, production order management, improve productivity and ensure maximum precision and the ability to muster equipment manufacturers have a major impact. In this fixture design, by analyzing the structure and process-specific compressor design a set of appropriate technology and equipment to design simple, efficient CNC special fixture, finally worked out supporting manufacturing processes.
