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).

Machining is a term used to describe a variety of material removal processes in which a cutting tool removes unwanted material from a workpiece to produce the desired shape. The workpiece is typically cut from a larger piece of stock, which is available in a variety of standard shapes, such as flat sheets, solid bars, hollow tubes, and shaped beams.

Material Removal. In the machining process of material removal, the cutting tool removes the unwanted materials from the workpiece to produce the desired shape. The workpiece can be from a variety of stock materials such as aluminum, steel, titanium, wood, stone, ceramic, glass, etc., as well as from forged or casted materials.

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.

Aug 07, 2013 The removal mechanism for a brittle material is achieved through micro-fracture and the subsequent removal of the chips by the next passing grain (see Figure 1). The normal stress distribution profile associated with grinding a ductile material does not apply to grinding a brittle material like an advanced ceramic.

In creep feed grinding, the machine table feeds the work piece in the direction of the grinding wheel rotation. While the table speed is slow—“creep feed”—the depth of cut is very high, which results in a high material removal rate. The creep feed grinding process offered significant productivity enhancements over conventional grinding.

In this equation, G is the grinding ratio, which is defined as the volume of material removed per unit volume of wheel wear. G increases with less wheel wear and/or higher metal removal. The higher it is, the better the grinding conditions, especially in terms of longer wheel life. To determine G, one takes the equation: G = Vw/Vs
