Description
Summary:The round-off truing method for precision form grinding was proposed by the authors. The circular motion of a CNC grinding machine is utilized together with an abrasive stick or a brake truer. In previous studies, experiments and simulations were performed to clarify the mechanism and appropriateness of this method. Accurate truing for the precision form grinding, however, could not be realized through these studies. In this study, the mechanism of the round-off truing when there is a set-up angle between the truer spindle and the grinding-wheel spindle theta sub z has been clarified through vector analysis. The appropriateness of vector analysis and effect of theta sub z on the truing accuracy has been confirmed experimentally. The form error of the trued wheel surface shows the minimum value when theta sub z is in the range 10-20 degrees.
