A Study on the Stability of Curvic Coupling for Distance to Disk in a Mill Turret

Abstract:

Curvic coupling of mill turret should maintain disk weight and the cutting resistance, which occurs when the machining operation must have a power transmission function. In order to improve machining operation range, distance to the disk must increase as much as possible. But moment is increased by the lack of bearing capacity of the curvic coupling. Increase of moment is the cause of vibration/noise and degradation of machining performance, it not only a stability problem. In this study, a finite element analysis model of the mill turret is designed and considered in the method of equations for finding distance to the disk by structural analysis of Ansys workbench. Through the considered method, critical distance to the disk, and the stability of the curvic coupling are confirmed by increasing each value 10mm from 228.5mm
