Paper Abstract

A new 3-DOF parallel Coordinate Measuring Machine was proposed in this paper,which could realize 3D measured with only one linear grating and one precision guide. According to its forward kinematics and complete differential-coefficient theory, the error model was established; by deriving the inverse kinematic equations for the Jacobian matrix, it has been proved that the mechanism has no singularity within the working space. The input parameter errors and mechanical errors affecting the probe position accuracy are analyzed too. The prototype has been manufactured and assembled after theoretical analysis, now it can finish basic motion and simple test, the further study is in process, which will mainly focus on improvement of measuring accuracy and calibration method.
