The experiments were conducted on the surface grinding machine with a cylindrical grinding attachment at different combinations of grinding process parameters. Experiments were performed at two values of grinding wheel speed, i.e. 1400 and 2800 r.p.m., for both surface and cylindrical grinding operations. A total of 32 experiments were performed.

Difference Between Machining and Grinding

Cutting tool used in machining has specific geometry. Values of the geometrical features may vary from one tool to another, but each tool has pre-defined geometry as per tool signature. Grinding wheel may have specific pre-defined features, but the abrasive grits (which actually participate in material removal) have random geometry and orientation.

Grinding Force - an overview | ScienceDirect Topics

The deflection that results from the grinding force depends on the stiffness of the machine including the grinding wheel and the workpiece. For simplicity, these are all lumped together in one frequency-dependant stiffness parameter γ(jω), where the Greek symbol lambda is for stiffness and omega indicates that the stiffness varies with frequency.
