1、制造工程基础Ⅱ复习提纲（刀具、机床、工艺部分按冯之敬清华出版社《机械制造工程原理》的章内容）第一章金属切削基本要素1切削运动和切削用量1）切削运动：成形运动和刀具是实现工件切削加工过程的两个基本要素（由主运动与进给运动合成合成切削运动）2）加工表面：待加工表面（加工时即将被切除的表面）已加工表面（已被切去多余金属形成符合要求的工件新表面）过渡表面（加工时由主切削刃正在切削的表面）3）切削用量：切削速度，进给量（转一周沿进给方向的位移），切削深度2刀具几何角度1）刀具切削部分的结构要素：前刀面（切屑流过的表面）、主后刀面（与主切削刃毗邻，
2、且与工件过度表面相对）、副后刀面（与副切削刃毗邻且与已加工表面相对）、主切削刃（前刀面上直接进行切削的边锋）、副切削刃、刀尖（交点、圆弧、倒角）2）刀具标注角度参考系参考平面：基面、切削平面、副切削平面测量平面：主剖面、主剖面参考系、法剖面、法剖面参考系3）刀具标注角度（要求：能够严格按照画法几何原理绘制刀具切削部分的图形并标注外圆车刀六个基本角度）（1）主剖面参考系中的标注角度基面内标注角度：主偏角（切削平面与进给平面）、副偏角主剖面内标注角度：前角（基面与前刀面）、后角（后刀面与切削平面）、切削平面内标注角度：刃倾角（主切削刃与基面
3、）副剖面内标注角度：副后角（）六个基本角度：前角go、后角ao、刃倾角ls、主偏角kr、副偏角k’r、副后角a’o（2）法剖面参考系中的标注角度：法前角（前刀面与基面）、法后角（切削平面与后刀面）loanmanagement(post)review:1,approvalcriteriahavebeenimplemented;2,thecontractiscorrect;3,inlinewiththecontract,payment;4,noothermajorcasesagainstloansecurity;、Reviewedby:da
