Energy and temperature analysis in grinding

The effect of wheel sharpness is highlighted by a creepfeed example from Andrew, Howes and Pearce [12]. C1023 Nickelbased alloy is a temperature resistant alloy used in the aerospace industry for turbine blades. Because the material is temperature resistant, it retains its hardness at higher temperatures. This increases specific energy required and wheel wear is rapid as .
