Abstract
Workpiece out-of-roundness is one of the most important problems in centerless grinding. Besides geometrical and kinematical effects, the dynamical behavior of the machine structure, the grinding and regulating wheel together with the support blade fundamentally influence the process stability and the workpiece accuracy. The paper presents a method for a numerical simulation of plunge centerless grinding processes in time domain. Under consideration of the geometrical conditions of the grinding gap and the dynamical compliance behavior of the grinding system the developed algorithm enables a quantitative determination of the workpiece out-of-roundness, the progression of grinding and reaction forces as well as the calculation of dynamical displacements.
