The advantages of parallel coordinate measuring machine and the design of parallel six coordinate measuring machine are introduced. The main factors influencing work space are analyzed, and the constraints of parallel rod length, kinematic secondary angle, parallel rod interference and structural constraints are deduced. A one-dimensional search method is used to determine the boundary of the workspace and the volume formula is deduced
