Material Removal Rate - an overview | ScienceDirect Topics

Material removal rate in grinding is usually quoted in terms of removal rate per unit width of grinding contact. Removal rate per unit width is known as specific removal rate Q′. Using the specific removal rate reduces the number of variables and allows direct comparison of removal efficiency across a wide range of operations (Fig. 2.7).

In 2002 ductile iron accounted for 31% of casting shipments from 13.14 billion tons in the US. Although pressure pipes are a large portion of this market components for the car, truck and power transmission sectors account for 27% of these ductile iron shipments [1].

Energy and temperature analysis in grinding

where the grinding power is 25 watts per cubic millimetre of material removed per second for a particular workpiece material, the specific energy is 25 J/mm3. For a harder-to-grind workpiece material being machined with a fine-grain wheel, the specific energy might be as high as 200J/mm3.

8 Principles of Centerless Grinding

Dec 08, 2016 · A downside of centerless grinding is you can’t have as many multiple axes operating on the workpieces. However, there are many parts where the process addresses the limitations of machining in terms of dimensions, materials, and surface finishes. That’s why we like to say that where machining ends, the centerless grinding process begins.
