In this paper, some characteristics of both grinding force and residual stock removal are investigated, mainly paying attention to the effects of the rigidity of the tool and its backup supports. The results obtained here are summarized as follows.
(1) It becomes clear that not only worn grain flats but also arc of contact between the tool and workpiece have direct effects upon the characteristics of grinding force. Then a metal removal model which takes such factors into consideration is proposed here, and its validity is proved. It also derives effective parameters to evaluate grinding force.
(2) The relationship between normal grinding force and elastic displacement of the tool is nonlinear. It can be approximated as a quadric equation for practical analysis.
(3) Assuming that the formation of residual stock removal is caused only by elastic deformation of tool and its back-up supports, the residual stock removal is analyzed quantitatively, and it is confirmed that the theoretical results agree pretty well with experimental ones.
