Grinding operations were carried out using three grinding wheels which are different hardness type, and ground surface roughness and residual stock removal of the workpiece were measured. The contact stiffness of grinding wheel was calculated by a support stiffness of single abrasive grain and a contact area between grinding wheel and workpiece.
Surface grinding is used to produce a smooth finish on flat surfaces. It is a widely used abrasive machining process in which a spinning wheel covered in rough particles (grinding wheel) cuts chips of metallic or nonmetallic substance from a workpiece, making a face of it flat or smooth.
Roughness is usually regarded as one of the most important factors to evaluate the quality of grinding process and ground surface. Many grinding parameters are affecting ground surface roughness with different extents, however, the most influential factors are wheel dressing and wear effects which were unfortunately not get seriously attention in the previous researches.
Jan 01, 2017· In this work the 42CrMo4 steel ground surface integrity was evaluated at different grinding conditions before and after nitriding.

Surface integrity was characterized by roughness, micro-hardness, residual stress distribution and ground surface morphology.
Nov 28, 2019· Grinding parameters refer to grinding wheel speed, workpiece speed, grinding depth, and longitudinal feed. Increasing the speed of the grinding wheel may make the propagation speed of the plastic deformation of the surface metal not follow the grinding speed, and the material may not be deformed so that the surface roughness of the grinding ...

Dec 08, 2016· A downside of centerless grinding is you can't have as many multiple axes operating on the workpieces. However, there are many parts where the process addresses the limitations of machining in terms of dimensions, materials, and surface finishes. That's why we like to say that where machining ends, the centerless grinding process begins.

Jan 11, 2017· A grinding wheel with a rougher grit will remove more material per pass, but the result is a rougher surface finish. A finer grit will remove less material per pass, but give you a smoother finish. The drawback to a finer grit is the potential for clogging of the wheel and over heating of the plastic which results in burnishing or burning of ...
