Abstract
Recently the high speed machining centers have been developed with the high lead ball screw systems or the linear motor systems. And higher cutting technology has been also developed. So the stick motions become worse as the advance of the high speed technology. The stick motions that happen in the circular motion damage the accuracy and the quality of work pieces extremely. In the conventional compensation system, it is need to tune the compensation parameters for each combination of radius and feed rate. In this research, a new stick motion compensation system is proposed. The new system has a dynamic model that simulates the friction system. And it is able to compensate the stick motions suitably for wide range conditions of radii and feed rates.
