螺纹编程指令介绍及多头螺纹的编程技巧

The Screw Program Instruction And The Program Technique of Multi-start Screw Thread

详细介绍了在数控车床上加工螺纹的编程指令G32、G92、G76的具体含义,并分析多头螺纹的加工原理,通过实例说明单头螺纹和多头螺纹的编程方法,说明加工多头螺纹主要是需在Z轴方向上改变起点位置来实现分度。

The article is mainly about the meaning of programme instruction, such as G32.G92,G76, used in manufacturing screw threads on NC lathe in detail and analyses the principle about how to manufacture multi - start screw thread. The example of progrmmne- method about the single- start and the multi - start screw thread indicated that the multi- start screw thread can be made by changing the startpoint at theZ axis.
