A Study on the Technology of Helical Groove Formation
- 物理技术－会议论文 
On the basis of analyzing the geometric characteristics of the helical groove, the interferometry method for its processing is discussed. This paper establishes a mathematical model of the helical groove, using differential geometry theory and numerical analysis. This research analyzes the impact of machine adjustment parameters (i.e. setting angle) on the geometry specification (i.e. Rake angle) of the helical groove. The simulation examples are done by CAD (Computer Aided Design), and the reasonable adjustment of machine parameters will be obtained by computer simulation and statistical analysis. This will reduce the time for design, the number of trial samples, and production costs. This study provides a precise 3D helical cutter model which can be used in areas such as finite element analysis (FEA) and virtual cutting tests.
