Jan 01, 2012· The second reason is a lack of understanding about the grinding process. ... The outputs were the ratio of wheel velocity to workpiece velocity to see if an integer value was found, along with a rough estimate of the waviness based on wheel runout using superimposed sine waves on the workpiece. The company was then able to use this to avoid ...

In cylindrical grinding, the feed velocity can also be oriented radial to the grinding wheel. In this case, the radial feed velocity v fr is defined. Depending on the grinding process, also the workpiece can have an actuating velocity which is not in every case equal to the feed direction. This velocity is then called the workpiece velocity v w.
During grinding of a hard workpiece, because of forces induced are higher and to withstand for this process, the abrasive particles must be very close. hence, the dense structure is used. Rough grinding of soft workpiece: 12-16. Finish grinding of soft workpiece:7,8,9. Rough grinding of hard workpiece:6,7,8. Finish grinding of hard workpiece:<5.

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.
