一、此套设计有全套CAD图和卡片，有意者请联系我索取522192623@ 机械制造工艺课程设计是在全部学完机械制造工艺学及机床夹具设计课程，并进行了生产实习的基础是进行的一个教学环节。它要求学生全面地综合运用本课程及其有关先修课程的理论和实践知识进行工艺及结构的设计，也为以后搞好毕业设计进行一次预备训练ABSTRACT This topic is mainly design that designs the tail a body of some tool machine to process the craft and tongses, adopting to design first in the design a body of that tail processes the craft at according to process the craft to select by examinations the tongs of the project of the design and concrete design of the tongs;But the point of design is the design of the tongs.Because the bore of the work piece 17 and 14 all want to face to be used as the basis to process with the bottom, past have to do a bottom to face first of process the tongs.Because bore 17 of accuracy have high request, and position the size error margin small, for guarantee the position of the bore and process the accuracy we certainly at process the bottom to face of time pass to draw the line to find out the bottom to face of process the amount of remaining.Thus can with better assurance bore 17 of position and process the accuracy!Process the bore 14 of tongs was in processing the foundation that the bottom faces the furniture to add one 45 degrees of gradient plank in fact.Process the bore 17 of time is opposite for assurance to run parallel with B face of in the A we have to design accurately with the AN and B faces to settle for of tongs!Return in consideration of a degree of the work piece and the error margin of the cylinder degrees are small, the furniture that we design have to the bore 17 of tongs fixed position is accurate, and process the vibration of time small, that have to in the bore 17 of neighborhood seek a fixed position to step up the point! 目 录 序言 1 1. 零件的工艺分析及生产类型的确定 2 1.1.零件的分析 2 1.2.零件的生产类型 2 2. 选择毛坯，确定毛坯尺寸，设计毛坯图 3 2.1.选择毛坯 3 2.2.确定机械加工余量 3 2.3.设计并确定毛坯尺寸 3 3. 选择加工方法，制定工艺路线 4 3.1.定位基准的选择 4 3.2.零件表面加工方法的选择 4 3.3.制定工艺路线 5 4．工序设计 7 4.1确定工序尺寸 7 4.2. 选择加工设备与工艺装备XII 7 5. 确定切削用量及基本时间（工序Ⅸ） 9 5.1.切削用量的计算 9 5.2.基本时间tm的计算 9 6.
