摘　　要：微V槽被广泛应用于光纤连接中,其中心距是决定其性能的关键。热误差是数控1加工中最大的误差源之一。根据微V槽超精密机床的拓扑结构,采用多体系统理论算出影响微V槽中心距加工精度的热误差共有10项,再结合多元线性回归理论对这10项热误差项进行辨识。Micro v-groove is extensively used for planar optical-fiber alignment,and its core pitch tolerance is critical to the functionality of the fibre connector. Thermal error is one of the biggest errors in NC machining. According to the topological structure of ultra-precision micro v-groove machine tool,ten components of thermal error which influence the core pitch tolerance of micro v-groove are computed using a multi-body system theory,and they are identified through multiple linear regression theory.
