Profile Grinding. Profile grinding is also known as projection, form, and copy grinding. In this process, a workpiece is projected at a magnification of 20 times onto a product shape drawing that is projected in advance like a shadow picture. A grinding wheel is operated by numerical control (NC) or manual control, and copy grinding is ...

A thin double-bevel wheel with a circular edge in cross section is typically used in profile grinding. An ideal profile of a grinding wheel arc is shown in Figure 2(a). L 1 and L 2 are the two bevel edges. R is the radius of the wheel arc, and α is the radius angle. Both L 1 and L 2 are tangent to the wheel arc. L is the center line of the wheel …

Traditional force models fail to predict the grinding force for gear profile grinding accurately owing to the specific grinding geometry and kinematics. On the other hand, few researchers about gear profile grinding concern the grinding force. To address this issue, a model to predict the grinding force for gear profile grinding is proposed. …

The grinding processes can be distinguished in generating grinding and profile grinding though another classification of continuous and discontinuous processes has to be made, Fig. 3.In the past, the processes of discontinuous generating grinding had a high economic importance; companies like Niles and Hoefler for the machining of big …

The mesh for both, the grinding wheel and the workpiece that the profile was ground into, had to be fine enough to replicate all relevant parts of the profile, making the number of elements highly dependent on the complexity of the profile. For the grinding of a fir tree profile to a block sample of 50 mm length and 30 mm width, the mesh ...

A specialized grinding program was initiated in 2002 on the heels of a series of light-rail derailments on the Massachusetts Bay Transportation Authority (MBTA) Green Line that occurred in the summer of 2000. Figure 1. An initial study indicated that the 63-degree wheel flange angle on the cars was not sufficient to prevent derailments.
