Abstract
Machinery manufacturing is a national technological progress and social development one of the pillar industries, whether in traditional industries, or emerging industries, and is inseparable from the wide range of machinery and equipment Speeding up the time to market, improve quality, reduce costs and enhance service is the eternal pursuit of manufacturing theme. Main content of this paper is to VF- air compressor crankshaft processing routes (including a total of 53 processes) for the research, design, which includes the processing of a process, machine, tool, fixture, ATD, Gauge choice datum selection, positioning and clamping of programming; and the right processes Road No. 13, 28 (crude cars, Accurately crankshaft), which use a special truck design. This study is the main content of how to simplify processes and reduce processing difficulties so as to improve processing efficiency, accelerate time-to-market goals. Toward manufacturing towards the pursuit of the theme!
