Abstract
The design of parts for the lever parts of 45 steel. According to parts of shape, dimensional accuracy, cost-effective production areas such as a detailed analysis of its manufacturing processes, Most Drilling. Part of the analysis, the shape of the workpiece contour small size, light weight, low-processing, not mass production. Therefore the quality assurance and productivity, under the premise of the structure as simple as possible, so economically rational.
Keywords : Drilling, leveraged parts, dimensional accuracy 。
