Analysis of Three-Dimensional Circular Motion Trajectories of Five-Axis Machining Centres Simulating Cone-Frustum Cutting

Abstract

In the present paper, a mathematical model was developed to represent the pitch error of the axes of rotation of five-axis machining centers having a tilting rotary table. The parameters used in the model were determined based on data measured for simultaneous three-axis motion. In experiments and simulations, the center offset and half apex angle of the cone-frustum are varied. In addition, the sensitive direction of the ball bar is varied to be either perpendicular to the conical surface or
