Study on Error Analysis of Parallel Machine Tool Based on Monte-Carlo Method

Abstract:

Aiming at the complexity of the parallel machine tool error assessment, the distance between the ball joints on the execution platform is considered as the constraint condition to establish the forward kinematic equation, and a mathematic model of space position and attitude errors is established. The paper proposes a method to the error analysis of the parallel machine tool based on Monte-Carlo simulation according to the structure characteristic, and gives a universal computation program. The feasibility of the method is verified by comparing with the traditional motion vector equation differential method in final.
