Abstract
This paper deals with the analysis of work regenerative chatter in cylindrical plunge grinding of low stiffness workpiece. The effect of grinding parameters on chatter stability and chatter frequency is discussed in some experiments and a theoretical analysis. The chatter stability is examined experimentally by an angular grinding which is a high efficiency grinding method, and it is analyzed to first approximation by the application of the regenerative chatter theory for usual plunge grinding. Dynamic grinding force due to the relative penetrating velocity of the grinding wheel to the workpiece is considered in this chatter theory. The following conclusions are obtained. (1) To increase the structural stiffness results in low chatter stability with the lower stiffness of the workpiece. (2) The chatter theory for usual plunge grinding does not matter in a practical application to the chatter stability analysis in cylindrical angular grinding of the low stiffness workpiece. (3) Plunge velocity scarcely affects the chatter frequency.
