A method and apparatus for_cutting a profile in a workpiece, such as a turbine disk, without cracking the parent material which includes providing a grinding wheel having a ceramic grinding surface formed with an optimized grain material and grain spacing to produce large chips that are easily removed from the workpiece, applying the grinding wheel to the workpiece at a predetermined material removal rate, and increasing the material removal rate when the burning point is recognized at the surface of the workpiece by the grinding action of the grinding wheel, and delivering coolant/lubricant to the workpiece during the grinding operation.
