METHOD OF GRINDING WORKPIECE, JET GUIDE APPARATUS, AND JET REGULATION APPARATUS THEREOF FOR PROCURING ABRASIVES TRAVEL ALONG PROCESSING SURFACE OF WORKPIECE

摘要

PURPOSE: A method of grinding a workpiece, a jet guide apparatus, and a jet regulation apparatus thereof are provided to procure abrasives travel along a processing surface of the workpiece by setting an incident angle of abrasives to the processing surface of the workpiece within a predetermined range. CONSTITUTION: An injecting process is performed to inject an abrasive together with compressed fluid to a processing surface of a workpiece with an incident angle to meet the condition in which V*sin theta1 is bigger tan zero, smaller than 1/2*V or the same with 1/2*V where V is speed of the abrasive in an injection direction and theta is the incident angle of the abrasive to the processing surface of the workpiece. A generating process is performed to generate a jet of the abrasive along the processing surface of the workpiece.
