- Abstract
In order to determine the key factors which have an impact on the machining accuracy of a machine tool after its machining errors occur, a different method analyzing the sensitivity of machine tool errors based on the theory of multi-body system kinematics is proposed. Firstly , the method assumes a machine tool to be several rigid bodies according to the theory of multi-body system kinematics , establishes the body reference coordinate system and the kinematic reference coordinate system on each rigid body, and constructs the constraint equation by using the method of describing the center of the tool and the machining point in the system coordinates to solve the machining errors of the machine tool. Then, it gives the sensitivities of error parameters by taking the derivative of errors and establishes the impact analysis model. The calculation and analysis for an example show that when using the method the fundamental factors that have significant influence on machine tool errors can be identified efficiently. It can provide the theoretical basis for designers and users to improve machine tools.
