Development Process of Work-regenerative Self-excited Chatter Vibration in High Speed Plunge Grinding and the Strategy for It

Abstract

With an increase of wheel speed in cylindrical plunge grinding the safety and the grinding accuracy can be reduced by the resulted work regenerative self-excited chatter vibration in grinding process. In this paper the development process of the self-excited chatter vibration is analyzed, and the prevetative guideline to the set-up conditions for the above problems is shown by considering the limited saturation of the chatter caused by the geometrical interference between the wheel and the work in regenerative effect.
