Shaft with high transmission efficiency, compact structure and long service life and a series of advantages, is the universal machine isone of the most important parts in the transmission of Engineering machinery. Shaft processing materials, heat treatment, machining process optimization, to improve the machining quality and the life of shaft has significance. In an enterprise to provide "axis" parts of the machinery manufacturing process planning and keyway milling fixture design. For the process design and fixture design for two different sets of programs, select the best solution from zhen. Firstly this paper analyzes the role and process of shaft parts, then order for the design process, the final design of special fixture keyway milling. Comprehensive mechanical performance requirements of high shaft parts, generally as blank forgings. Reasonable process route arrangement, division stage of processing is very important to ensure the machining quality of parts. The use of fixture can reduce the auxiliary time, improve labor productivity, guarantee the processing precision, stable processing quality, reduce the technical requirements for workers, machine technology to expand the scope of. In this paper, the precision of calibration and positioning error of the special fixture design analysis, design quality of the
