Theoretical and Experimental Analysis of Grinding Stability of Beam Workpiece

Grinding chatter is a kind of self-excited vibration in which the grinding system continuously absorbs energy from machine, increasing mechanical system. can damage surface workpiece and accelerate abrasion wheel. The theoretical analysis for beam was launched based on behavior single abrasive grain, whose cutting thickness key factor affecting stability. dynamic force model has been developed, interaction interface between wheel workpiece. In this paper, rail taken as an example. performance described with Timoshenko beam. characteristics frequency domain wheel-workpiece were observed, condition stability at any position longitudinal direction gained, could be quantitatively characterized limit curve. experiments demonstrated that marks investigated rail, signal mainly concentrated around frequency, higher than natural
