Sep 13, 2013· This study investigates the formation of the layer hardened on a cylindrical workpiece by grinding-hardening using the traverse grinding method. A finite element heat transfer model, that took into account the helical trajectory of the of the grinding heat source movement, was developed.
In order to achieve high accuracy and surface quality during traverse grinding of long, slender workpieces, multiple workpiece steadies with soft supporting pads should be used. Due to the complex interaction between the workpiece and the steadies and also the deflection of the pads the control of the steadies becomes difficult.

Abstract. In the present work, experiments and analyses have been made to investigate the influence of machining parameters on vibration and surface roughness in traverse cut cylindrical grinding of stainless steel material.
Good surface finish is one of the important demands from the outputs of a cylindrical grinding machine. Also it is expected that dimensional accuracy, including accuracy in roundness, is fine in traverse cut cylindrical grinding. Now, like any other machine tool, cylindrical grinding machines also do vibrate, and vibration will affect accuracy and surface finish of the parts produced in grinding.

In this paper, the workpiece regenerative chatter during cylindrical traverse grinding is theoretically analysed. The depth of cut, which is closely related to the grinding stiffness and the contact stiffness, is assumed to change stepwise in the wheelwork contadt area due to the elastic deformation between the grinding wheel and the workpiece.
