The Computer-Assisted Design Method of Staggered-Tooth Milling Cutter for Manufacturing of the Complex Helical Surfaces

Article Preview

Abstract:

The complex helical surfaces specific for the rotors of the helical compressors and of the screw pumps imply the production of a series of tools providing a high productivity. The staggered-tooth milling cutter achieve these conditions but their design gives rise to difficult problems. In order to optimize their parameters and to facilitate their design, a package of programs has been created to select the constructive parameters of the tool, to calculate the profiles of the plates, the angles of the surface of section, the dimensions of the elements of attachment. In order to include all these elements in an efficient system of design, a series of regular calculations were applied for various parameters that were then included through the CAD software for design and documentation AutoCAD; at the same time, several applications of verification, construction and simulation of the functioning of the tool and of the cutting process were designed. The method applied in this case reduced to a considerable extent the time of design and it also improved the constructive solutions of the staggered-tooth milling cutter.
