and the CNC system to perform calculation and control, and issue instructions to control the servo motor to move through the ball screw to control the tool, so as to realize thread turning. Let the thread turning do not have random threading when cutting the tool,...
An Interpolation Method for Thread Cutting \\ in CNC Lathe A simple and easy interpolation method for thread cutting is introduced. X Peng - 《Machinery & Electronics》 被引量: 7发表: 1997年 Explicit optimization method for cutting-screw-thread on the basis of dual-RSM To obtain the explicit...
Screwcutting may be undertaken on the lathe and the cutting tool is shaped to match the thread angle. Generally the thread terminates in an undercut and this feature is illustrated in Fig. 17.18. It is a normal draughting practice to draw an undercut in line with the minor diameter of the...
Based on the point-by-point comparison principle, a new interpolation algorithm for screw thread NC machining trace control was proposed, mathmatical model, calculation program and calculating process of the interpolation algorithm were introduced. Comparative analyses and practical application to lathe NC...
The segment ADi lies on the generating L and is the cutting edge of the cutter. The plane defined by the triangle ADiM2 is the rake plane of the thread lathe tool. At the same time, the segment ADiM2 is parallel to the Z-axis, and its length, |𝐷𝑖𝑀2|DiM2, determines the...
