Research on Position Keeping Technology of FIVE-axis CNC Machine Tool under Abnormal State in Fixed Angle Machining of Swing Shaft

Abstract

The swing shaft of five-axis CNC machine tool is usually used for fixed angle machining of products. The reliability of the position state of the swing shaft directly affects the quality of product processing. In this paper, aiming at the problem that the servo position changes in the abnormal condition during the fixed swing Angle machining of the B axis of a five-axis CNC machine tool affect the machining quality of the product, a set of methods and devices to solve the above problems are proposed and designed from the aspects of mechanical, electrical and hydraulic system analysis, and realize the maintenance of the angle position of the product under the abnormal state of the fixed swing angle machining of the machine tool. So that, the product processing quality is guaranteed.
