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.

Grinding is a complex material removal process with a large number of parameters influencing each other. In the process, the grinding wheel surface contacts the workpiece at high speed and under high pressure. The complexity of the process lies in the multiple microscopic interaction modes in the wheel-workpiece contact zone, including cutting, plowing, sliding, chip/workpiece …

Grinding is regarded as a special multiple edge cutting process, which can be decomposed into grain-workpiece interface, chip-workpiece/bond interface, and bond-workpiece interface at microscopic level. The grain-workpiece interface, which resembles a micro-cutting process, directly modifies the workpiece surface and dominates all the output measures of a grinding …
