数控车床车网纹（CNC lathe mesh） Cart program 1 multi thread turning function car, reticulate flowers The processing principle is that the mesh is considered as a cross thread of positive and negative interleaving. In the 1 part as an example, the traditional processing technology for the first except knurling and 1.6 hole process of vehicle system, and then rub rub flower gardener installed, finishing with 1.6 holes. Because of the higher requirement of the shape and position tolerance of the knurling, and the two clamping, the construction time is long and the reject rate is high. After the new processing technology is adopted, because all the steps of the parts are finished by clamping at once, the machining accuracy can be easily guaranteed. Specific macro procedures are as follows: CNC automatic bar lathe (Swiss type) multi thread instruction format: 1 G32IP-, F-, Q-; (IP-: end point, F-: long axis pitch, Q-: thread starting angle) ............

Use this phenomenon can also be out of mesh flowers. But this method is suitable for rolling parts with small number of threads and small spiral angle, and can increase the spindle speed at the same time. The application also looks at the specific situation, and this paper aims to introduce a method. As shown in figure 1. Procedures are as follows: ..
