This is our prior to graduation design to learn the course of an in-depth prehensive review of the total, is also a theory with practical training . therefore, it occupies the important position in our four years of University life. First of all we must familiar with the parts, the parts subject to the end cover. Understand the role of the cover, then according to the nature of parts ponents in the face of the map on the roughness determine the size and mechanical The machining allowance. According to another location and then we set the benchmark fine first base, established after the benchmark crude, finalizing the cover of the road map, the enactment of the workpiece clamping programme. In terms of special fixture design,first of all we have to understand that zhe fixture has played a very important role in parts processing. The function of machine tool fixture can be summarized as the following respects: 1 Machine tool fixture can accurately determine the workpiece and the relative position between th
