【Abstract】 The significance of developing parallel mechanism CMMs is introduced. The parallel mechanisms that can realize six-coordinate motion are discussed. The evolved Stewart platform is defined as the structure of six-freedom-degree parallel mechanism CMM. According to the closed circuit space mechanism, the freedom-degree of defied structure is analyzed. The working principle of six-freedom-degree parallel mechanism CMM is introduced and its control and measuring system is designed.更多还原
