Abstract

Recently, high speed and high precision machining is required. Contouring error is caused in high speed and high acceleration motion due to the differences of servo parameters. In this research, the influence of the difference of the servo parameters between two axes on contouring error is evaluated by using sensitivity of servo control systems. When the difference of the servo parameters between two axes was small, contouring error was estimated by sensitivity. It was simulated that contouring error was reduced by tuning position command.
