Abstract: A motion model of tangential point tracing grinding has
established according to the principle of grinding point’s uniform
motion on the neck of connecting rod, and a new idea that changes the
crank tangential point tracing grinding into the state of common
external grinding is described through coordinate converting. According
to the motion model, the influence of machining error caused by the
tangential point tracing is analyzed. The influence and change rules of
equivalent grinding thickness and grinding force of the tangential point
tracing motion are discussed. The computer formula of NC compensation
and the revised motion model are given.
Key words: Crank Tangential point tracing grinding Motion model
