Grinding is a combination of rubbing, ploughing and cutting (actual chip formation) . A certain level of grit penetration into workpiece is required before chip formation can start. Magnitude of critical grit depth of cut required to initiate cutting becomes less with the increase of grinding velocity.

When the details of a specific grinding task—workpiece material, type of grinding wheel, dimensional tolerances, surface finish requirements and so forth—are loaded into the model, the system will determine the machine settings, wheel speed, depth of cut, dressing frequency and other parameters required to optimize the operation.
A series of grinding tests are performed to obtain burn variation with grinding parameters using different grinding wheel and workpiece in this paper. Grinding energy is also recorded and used to evaluate the influence of grinding parameter on burn.
grinding zone using an entry and exit nozzle. Other grinding parameters are listed in Table 3. When grinding Inconel 718, there is a high probability of adherence of grinding debris to the wheel. Therefore, a cleaning jet, located away from the grinding zone, and operating at a pressure of 34 bar was directed towards the wheel.

and θ is the workpiece rotation angle measured from the grinding start point. The angles εB and εC depend on the friction coefficients between the workpiece and the blade, the regulating wheel, respectively. The angle εG is determined by the ratio of normal component of grinding force to its tangential component.
To do this, the grinding wheel must be moved to an exact position relative to the workpiece. Therefore, a grinding machine must be very stiff and its axes must move with very high precision. A honing machine is relatively accurate and perfect.
converted into heat . For a given set of grinding parameters, heat is directly proportional to temperature  according to: The partition ratio, or the fraction of grinding power which enters the workpiece, can be estimated. The contact area, arc length, workpiece velocity and workpiece thermal properties are all known or readily calculated.
