ANALYSIS OF THE INFLUENCE OF A PERTURBING FACTOR ON THE STABILITI OF THE FACE MILLING PROCESS

Authors: M.E. Iremadze, A.I. Khvadagiani


Abstract:

The influence of the perturbing factor on the stability of the face milling process was analyzed. The results of a statistical analysis of production data on radial run-out of the teeth of the face milling cutters are presented. The analysis of the presented results indicates the general patterns of changes in run-out of the teeth depending on the diameter of the cutter and the number of teeth. Through statistical generalization of the experimental data, there have been obtained the mathematical models of the relationship between run-out of the teeth and its statistical characteristics on the one hand, and the diameter of the cutters and the number of teeth, on the other hand. The models have been developed as the linear logarithmic polynomials. The resulting models can be used for a preliminary quantitative evaluation of run-out of the teeth, followed by an evaluation of its effect on the stability of the milling process.

Keywords: face milling; disturbing factor; instability; run-out of the cutter teeth.
