Title:
METHOD FOR PREDICTING THREADED-WORKPIECE SURFACE TOPOGRAPHY DURING WHIRLWIND MILLING
Document Type and Number:
WIPO Patent Application WO/2023/138327
Kind Code:
A1
Abstract:
Disclosed in the present invention is a method for predicting threaded-workpiece surface topography during whirlwind milling. In the method, the surface topography characteristics of a workpiece are analyzed by using a multi-cutting-edge intermittent forming process characteristic of dry thread milling. According to a surface topography forming mechanism of a threaded workpiece, a thread raceway surface residual height prediction model and a thread raceway surface waviness prediction model are built, and the effects on thread raceway surface topography of parameters such as cutting parameters, an undeformed chip thickness, the minor and major diameters and the helix angle of a thread, the number of cutting tools, the geometric dimensions of the cutting tool, and a workpiece-to-cutting-tool eccentric distance are taken into consideration. By means of a workpiece surface topography prediction model, machining parameters can be optimized in advance, so as to obtain the optimal machining solution, thereby improving the machining quality of whirlwind milling.
