grinding revealed that apart from the rounding mechanism, one of the main problems is related to the variation in workpiece speed along the grinding gap. The workpiece speed was measured with eddy current sensors mounted into a coolant needle nozzle. In order to attain a steady feed rate along the grinding gap the workpiece has to be in ...
The centerless grinding process is characterized by a particular workpiece (WP) holding system. The WP is supported on three points by the grinding wheel, the control wheel and the workrest, also called supporting blade (see Fig.1).This configuration makes the process prone to roundness errors, depending on the initial setup of the machine []: WP center can oscillate and create a polyhedral ...
