Abstract: Mechanism
and dynamic model of spindle rotation induced error compensation (SREC)
is addressed with theoretical analysis, computer simulations and
experiments. The mechanism of dynamic interaction between the spindle
rotation induced error and compensation cutting system is discussed
through composite vibration mechanism analysis of spindle rotation
induced error disturbance. Based on the above analysis, a new dynamic
model of SREC cutting system is presented. The dynamics of SREC cutting
process of boring is addressed in details from both Laplace S frequency
domain and the time domain with simulations. Theoretical analysis and
simulation experiments show, for the first time, that the compensation
displacement effect is affected by not only the systematical stiffness
of workpiece, spindle and tools, but also the regenerated coefficient of
cutting process. The final results indicate the SREC is practicable in
reality to decrease the cutting error in many engineering application.
