有色金属零件表面粗糙度大Ra值要求较小时，不宜采用[[磨削加工]]，需要用车削或[[铣削]]等。用金刚石车刀进行精细车时，可达较高质量。

1） 用三爪自定心卡盘装夹工件进行粗车或精车时，若工件直径小于30㎜，其悬伸长度应不大于直径的5倍，若工件直径大于30㎜，其悬伸长度应不大于直径的3倍。
这些决定着加工时间、刀具寿命和加工质量。经济有效的加工方式必然是合理的选择了切削条件。
切削用量的三要素：切削速度、进给量和背吃刀量。<ref>[http://m.sohu.com/a/201073718_784717 常用车削加工计算公式，简单而易懂],搜狐网，2017-10-29</ref>
伴随着切削速度的提高，刀尖温度会上升，会产生机械的、化学的、热的磨损。切削速度提高20%，刀具寿命会减少1/2。
进给条件与刀具后面磨损关系在极小的范围内产生。但进给量大，切削温度上升，后面磨损大。它比切削速度对刀具的影响小。
切深对刀具的影响虽然没有切削速度和进给量大，但在微小切深切削时，被切削材料产生硬化层，同样会影响刀具的寿命。<ref>[https://tech.hqew.com/news_236723 切削运动与切削用量],华强电子网，2016-08-10 </ref>
用户要根据被加工的材料、硬度、切削状态、材料种类、进给量、切深等选择合理的切削用量。

1. 进入训练场必须听从指导教师安排，穿好工作服，戴好防护镜，头发长的同学戴好工作帽，操作时严禁带手套，认真听讲，仔细观摩，严禁嬉戏打闹，保持场地干净整洁。
