Modeling of shaping process and analysis of gear wheel cutting process by means of AUTOCAD and ANSYS software

Abstract

In the present paper methodology of computer aided geometric modeling of formation of workpieces with periodic teeth machined with centroid enveloping method is developed without involving complex mathematical apparatus. During its application, as opposed to already known methods, simultaneous modeling of two objects of formation – wraparound and removed contents – takes place. Analysis of configurations of solid models of cutaway layers and respective removed content volumes allows a design engineer to intentionally set the optimal values of tool advance parameter and number of passes. The key point of the present paper is to establish logical connection between geometric computer simulation of removed contents in CAD environment and analysis of chip formation in the process of cutting using ANSYS software. In the present paper AutoCAD 3D simulations rendering of cutaway layers is shown along with the corresponding realistic simulation of chips, created using metal cutting process finite element analysis software. Due to substantial difficulties of cutting process 3D simulation, it is considered reasonable to perform computer simulation of cutaway layers geometry generation on the first stage of problem solving. This will allow us to choose the optimal cutting parameters and consequently speed up the cutting process simulation.
