new cutting method of the thin copper pipe with two straight turning tools isintroduced, and the calculation of its main parameters is provided.
介绍了一种新的直型刀具切割薄壁铜管的方法，提供了其主要参数的计算。
In the case of keeping the longevity of the NC cutter,the author did some experiments to fix the NC milling parameter which can bring a higher metal cutting rate and tried to establish the proportion among the NC cutter diameter,cutting depth,cutting width,feeding velocity and spindle speed.
针对数控铣削参数的选择进行定量地讨论,在保证实际刀具寿命条件下,通过少量试验快速确定具有较高金属切除率的铣削参数,意在建立刀具直径与切削深度、切削宽度、进给速度和主轴转速等铣削参数的比例关系。
The applications of user subprograms,macroprograms and tool plane exchanging in NC milling programming are introduced briefly.
简略介绍了用户子程序、宏程序及刀具平面转换在数控铣削加工编程中的应用,并以实例的形式进行了其应用说明,对读者有借鉴作用。
