RESEARCH ON IMPROVING ERROR COMPENSATION ALGORITHMS IN BALL SCREWS
Abstract
Ballscrew drive is a mechanical mechanism that is said to have a relative motion relationship between the rotation angle of the screw shaft and the displacement of the nut - this relationship is linear, making them a natural choice for designing high-precision machinery and CNC machines due to their ease of calculation and control. However, in practice, many objective factors clearly cause inaccuracies in measurement results compared to calculations – leading to errors in machine design and manufacturing – making it difficult to master the design and production of automated and high-precision industrial machinery/equipment using ballscrews drive. Based on in-depth researchs on factors affecting the operating error of ballscrews, the author proposes supplementing and modifying a program to calculate and control error compensation for the control system, contributing to improved accuracy.
