Abstract: In the new grinding method of tangential point tracing
grinding, the machining error caused by the elasticity displacement of
crankshaft because of it’s poor rigidity is one of the most important
causes affecting grinding precision and machining efficiency. To
compensate this error, the crankshaft’s stiffness error is analyzed when
using the method of tangential point tracing grinding in the machining
of the connecting rod of crankshaft. On the base of the analysis above,
a mathematical model of stiffness-error compensation of crankshaft is
established. At the same time, the general method of calculating the
elasticity displacement of crankshaft in the process of grinding is
proposed as well.
Key words: Tangential point tracing grinding Stiffness Error
