【Abstract】 In order to overcome right-angle mechanism CMM’s restriction for rigidity, precision, velocity and flexibility in theory, the thought is put forwarded that developing our country’s parallel mechanism CMM The structure of known CMM, and parallel mechanism that can realize six-coordinate motion are discussed For the sake of predigesting the difficult of finding the position solution, evolved Stewart platform is defined as the structure of six-freedom-degree parallel mechanism CMM According to closed circuit space mechanism the freedom-degree of defied structure is analysed更多还原
