correlate carbon depletion in mild steel chips to the heat pro-duced at the grinding zone. Carbon content in chips after grinding were compared against base data generated by heating the workpiece material to various temperatures and studying the carbon content. The obtained results of such a comparison gives one an estimate of the temperature ...

The action of grinding wheel is very similar to that of a milling cutter. The wheel is made up of a large number of cutting tools constituted by projected abrasive particles in the grinding wheel. Definite elongated metal chips varying in size from 0.4 to 0.8 mm can be seen by examining the material removed under the microscope.

This idea was first suggested more than 90 years ago [2], and optical microscopy of grinding debris (swarf) more than 50 years ago revealed chip-like shapes [3 5]. With the advent of the electron microscope, the similarity between grinding chips and larger-scale metal-cutting chips became much more apparent [6 8].

In fact, grinding is often considered a subset of cutting, and vice versa, since each grain of abrasive on a grinding wheel acts like a microscopic, sharp cutting edge that shears a tiny chip from a part surface. In general, precision metal grinding processes are used to remove small amounts of material in order to achieve a particular finish ...

Grinding is a machining process improving the surface finish of the job and producing small chips. The tool used for this process is the grinding wheel. It is a cutting tool in which millions of microscopic abrasive grains are bond together. Here, each abrasive grain acts like a spiky tool. As shown in the image, the abrasive grains are held ...
