摘要
多齿分度是一门新型圆分度技术，因其分度精度高，荣获“角度基准”之称，宜用于精密测量。本文研制的差动式多齿分度台，目前国内尚不多见，文中对其结构设计、主要工艺、检测方法等进行了较深入的研究和论述。
Multitooth indexing is a new technique in circumferential indexing,and has been known asangle datum for its high precision. It is suitable for precision measurement.A new differential muItitoothindexing table has been developed and reported in this paper with an analysis and description on itsstructural design,main technology employed and inspection methods.
