As the workpiece hole 17 and 14 to the bottom asa base to be processed, it must first be processed to make the underside of the fixture. As the hole 17 of the high precision, small error size and location, to ensure the accuracy of hole location and we will process the underside of the processing time by drawing lines to find the bottom of the allowance. This will better ensure the hole 17 of the location and precision! Processing holes 14 of the fixture is actually the underside of the fixture in the processing based on the board of a 45-degree slope . 目录 1 零件工艺分析....................................................................................... 6 零件工艺分析及生产类型的确定............................................. 6 2 确定毛坯的种类和制造方法........................................................... 6 选择毛坯........................................................................................... 6 确定机械加工余量................................6 设计并确定毛坯尺................................7 3 拟定工艺路线............................ . ........ .7 定位基准的选择............................................................................. 7 表面加工方法的确定.............................................
