小型零件加工工艺与编程

摘要

数控车床是目前使用最广泛的数控机床之一。数控车床主要用于加工轴类、盘类等回转体零件。通过数控加工程序的运行，可自动完成内外圆柱面、圆锥面、成形表面、螺纹和端面等工序的切削加工，并能进行车槽、钻孔、扩孔、铰孔等工作,并且具有很高的精度.

Abstract

A CNC MACHINING CNC is currently to use the most extensive number to control one of the engine beds.The number controls lathe to be mainly used for processing shaft, pan etc. to turn round body parts.Control running of process the procedure through a number, can automatically complete inside the machining of metals of outside cylinder surface, conic surface, the forming work prefaces such as surface, thread and end etc., and can carry on car tank and drill a hole, expand operates, such as hole and Jiao hole...etc.. and has high accuracy.
