Table 9.Response table for S/N ratio of grinding temperature (V c ).The increase in the wheel velocity and workpiece velocity leads to the thermal softening of the aluminium matrix, which in turn, reduces the tangential grinding force [2]. The increase in the wheel velocity also reduces the maximum chip thick-ness, which results in a lower grinding force.

A process is applied for grinding cams of a camshaft (12) by means of a numerically controlled camshaft grinding machine (10). The camshaft (12) is arranged in a workpiece mounting (11) rotatably at preset angular velocity (ω) in predetermined angle steps about its longitudinal axis.

Here the workpiece rotational velocity, or rpm, decreases during the surge region and increases during the light-cut region, speeding up and slowing down during each workpiece revolution. But the road to grinding burn is paved with good intentions and this brought its own host of problems.

The grinding wheel usually performs the grinding action by having a higher linear velocity at the contact point than the workpiece. The other movable wheel is positioned to apply lateral pressure to the workpiece and usually has a rough or rubber-bonded abrasive to capture the workpiece.

The arc of contact in grinding is the portion of the circumference of the grinding wheel that is in contact with the workpiece. According to Foster, the longer the arc of contact, the more critical wetting becomes. "The correct velocity also is very important. A lot of people will flood the grinding area, but this is actually not beneficial.

Magnitude of critical grit depth of cut required to initiate cutting becomes less with the increase of ...

Principles of Grinding. In all forms of grinding, three different interactions occur between the abrasive and the machined material. Cutting occurs where the abrasive grain is sufficiently exposed to penetrate the workpiece material and curl a chip, and sufficient clearance exists between the grain, bond and workpiece to flush the chip with coolant or throw it away by wheel action.
