==车刀的装夹==
1） 车刀刀杆伸出[[刀架]]不宜太长，一般长度不应超出刀杆高度的1~1.5倍（车孔、槽、[[切断]]等除外）
5） 装夹车刀时，刀杆下面的垫片要少而平，压紧车刀的螺钉至少要用2~3个螺钉旋紧。

==工件的装夹==
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。
7） 车削轮类、套类铸锻件时，应按不加工的表面找正，以保证加工后工件壁厚均匀。

==切削用量的选择==
对于高效率的金属切削加工来说，被加工材料、刀具材料、[[切削用量]]是三大要素。
==车削技术训练安全操作规程 ==
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。
