Abstract:
An apparatus for controlling lobing and thermal-damage in centerless grinding, comprising:first means for providing an automatic controlled supporting device by which a periphery support of cylindrical workpieces of varying sizes is auto-formed in a work-holding stability status;second means for providing a flexible curved shoe structure for cradling a portion of a periphery of the cylindrical workpiece with an active-filtering mechanism by which a high frequency lobing is filtered out during a grinding process of a curved peripheral surface of the cylindrical workpiece and a lubricating material covering on a rear shoe provides a lubricating function to reduce heat over a contact area;third means for providing an on-line vision-based temperature control and monitoring device by which overheating on the workpiece is regulated; andfourth means for providing an on-line phase precession lobing control algorithm by which lobing is suppressed in a rounding process.
