2017 11 2 Abrasive finishing is one among several surface generation processes of which grinding process is a subset. In a typical grinding process six different interactions can be identified at the grinding zone resulting in surface generation. Among these six interactions one is governed by the principles of machining while the others are governed by the principles of

This step is followed by sectioning mounting grinding polishing and etching to reveal accurate microstructure and content. Detailed viewing of samples is done with a metallurgical microscope that has a system of lenses objectives and eyepiece so that different magnifications can be achieved for example 50X up to 1000X.

2011 4 1 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.

Surface finish measurements RMS Ra etc. describe the microscopic deviations of a surface from a perfectly smooth ideal plane. Note that surface finish is a different parameter than a machine part's flatness . Flatness refers to a machine part's bending bowing cupping or twisting with respect to a reference plane such as a granite

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

A microscopic grinding device grinds a workpiece at ultrahigh precision with the use of magnetic grinding fluid actuated microscopically in three dimensional directions by Z and XY axis actuators. The magnetic grinding fluid is magnetically supported between a grinding member and the workpiece by the magnetic field. Because magnetic field is generated to form a magnetic
