Structure of the grinding process model The understanding of grinding processes in terms of time dependent microscopic interactions indeed sheds light on the principles for the modeling. First of allthe wheel surface condition and its change in the process is the fundamental cause of the time dependent behavior of grinding.
The type of the grinding wheel used is another factor that influences the quality of the ground surface of the composite. When comparing the performance of two types of grinding wheelnamely AZ46I8V32A and AZ60J8V32A (type numbers are according to the American Standard Marking System)the results consistently indicated that the wheel with a softer grade (AZ46I8V32A) was superior to the one

Dec 152000 Centerless grinding workblade angles range from 0 to 45 degrees. For most centerless grinding applicationsa top blade angle of 30 degrees seems to provide the best results. The basic rule is the steeper the angle of the blade the faster the rounding action says Mr.
Centerless grinding is a machining process that uses abrasive cutting to remove material from a workpiece. Centerless grinding differs from centered grinding operations in that no spindle or fixture is used to locate and secure the workpiece; the workpiece is secured between two rotary grinding wheelsand the speed of their rotation relative to each other determines the rate at which material
