A method of removing material from a workpiece includes moving a coated abrasive over a receiving surface of a platen, the receiving surface having at least one opening configured for the flow of an ejection material therethrough, moving the platen and workpiece relative to each other to contact the coated abrasive to the workpiece and removing material from the workpiece, and controlling a flow pressure for the ejection material through the at least one opening during removing material from the workpiece, where the flow pressure of the ejection material can be adjusted based on at least one of the operation parameters such as a translation rate of the coated abrasive over the receiving surface, the weight of the coated abrasive, a material removal rate, a coefficient of friction between the coated abrasive and the platen, or a combination thereof.

Method and system for removing material from a workpiece

An abrasive grinding wheel having an annular grinding face depending from a substantially circular body includes a tubular inner wall which defines an axial bore configured to convey coolant in a downstream direction therethrough. The inner wall is coupled to a concave body portion terminating at an inner periphery of the annular grinding face. A flange having an outer periphery disposed, in representative embodiments, within about 20 mm of the inner periphery of the grinding face, is superposed with the concave body portion, to define a fluid flow passage between the flange and the concave body portion. The fluid flow passage is in fluid communication with the axial bore and with the grinding face, so that during operable rotation of the grinding wheel, coolant flowing downstream through the bore is conveyed radially outward into the fluid flow passage for delivery to the grinding face.
