2. Grinding wheel wear - Wikipedia

   en.wikipedia.org/wiki/Grinding_wheel_wear

   The quality, characteristics, and rate of grinding wheel wear can be affected by contributions of the characteristics of the material of the workpiece, the temperature increase of the workpiece, and the rate of wear of the grinding wheel itself. Moderate wear rate allows for more consistent material size. Maintaining stable grinding forces is ...

3. Tool wear - Wikipedia

   en.wikipedia.org/wiki/Tool_wear

   glazing occurs on grinding wheels, and occurs when the exposed abrasive becomes dulled. It is noticeable as a shine while the wheel is in motion. edge wear, in drills, refers to wear to the outer edge of a drill bit around the cutting face caused by excessive cutting speed. It extends down the drill flutes, and requires a large volume of ...

4. Grinding wheel - Wikipedia

   en.wikipedia.org/wiki/Grinding_wheel

   Grinding wheels are self-sharpening to a small degree; for optimal use they may be dressed and trued by the use of wheel or grinding dressers. Dressing the wheel refers to removing the current layer of abrasive, so that a fresh and sharp surface is exposed to the work surface. Trueing the wheel makes the grinding surface parallel to the ...

5. Electrochemical grinding - Wikipedia

   en.wikipedia.org/wiki/Electrochemical_grinding

   The abrasive particles bonded to the grinding wheel will help to electrically insulate the space between the grinding wheel and workpiece. [ 6 ] [ 7 ] An equation giving the material removal rate for an electrochemical grinding process is provided in [ 5 ] and is stated here as:

6. Speeds and feeds - Wikipedia

   en.wikipedia.org/wiki/Speeds_and_feeds

   Cutting speed may be defined as the rate at the workpiece surface, irrespective of the machining operation used. A cutting speed for mild steel of 100 ft/min is the same whether it is the speed of the cutter passing over the workpiece, such as in a turning operation, or the speed of the cutter moving past a workpiece, such as in a milling operation.

7. Wear coefficient - Wikipedia

   en.wikipedia.org/wiki/Wear_coefficient

   Traditionally, the wear of materials has been characterized by weight loss and wear rate. However, studies have found that wear coefficient is more suitable. The reason being that it takes the wear rate, the applied load, and the hardness of the wear pin into account. Although, measurement variations by an order of 10-1 have been observed, the ...

9. Centerless grinding - Wikipedia

   en.wikipedia.org/wiki/Centerless_grinding

   A schematic diagram of the centerless grinding process. Centerless grinding is a machining process that uses abrasive cutting to remove material from a workpiece. [1] Centerless grinding differs from centered grinding operations in that no spindle or fixture is used to locate and secure the workpiece; [2] the workpiece is secured between two rotary grinding wheels, and the speed of their ...
