Therefore, a grinding wheel model is a prerequisite for grinding process modeling, through which the microscopic wheel properties and their change as a function of time can be presented. Secondly, in order to specify and quantify the 6 interaction modes, some criteria should be deduced for the identification and modeling of each mode.

Macroscopic Approach. Microscopic approach. 01. This approach is certain quantity of matter without the events happening at molecular level. Events happening at molecular level is taken into account. 02. Macroscopic approach deals with the properties which can be sensed by humans. Or which can be obtained from mathematical relations.
