: Establishing geometric accuracy model is essential to conduct the accuracy prediction and inverse design of multi-closed-loop mechanism. Compared with the open-loop mechanism, accuracy modeling for multi-closed-loop mechanism is much more difficult due to the existence of negative factors like coupling and complex structure. In order to solve the above problems, a novel method of accuracy modeling is developed. First of all, the error sources are analyzed and modeled, and then two newdoi:10.1360/ze2002-32-5-628 fatcat:k7duy3e4azhdrokxfhsg7xjyga
