Abstract

Techniques of tool posts are developing such that variable machining is possible using only one machine for the complication of a product's shape and to reduce the machining time. In order to develop a mill turret with a variable machining function with the mounting of mill turret units on a B-axis tilting table, we determine the static/dynamic stability of the structure of the mill turret. To this end, a static structural analysis and a modal analysis were conducted. From the results of the static structural analysis, the maximum stress was found to be less than the allowable stress. By the comparing the results of the modal analysis of the excitation frequencies of the mill turret, there were no resonance regions found. Therefore, the mill turret with the B-axis tilting facility is shown to have good structural integrity.
