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.parameters controlling grinding processOct 11, 2002· Usually, the whole grinding process can be described by nine parameters: the roughing infeed velocity u 1, the finishing infeed velocity u 2, the roughing time t 1, the finishing time t 2, the spark-out time t 3, the wheel dressing depth a d, the wheel dressing lead s d, the wheel linear velocity V and the workpiece linear ...A review of cutting ﬂuid application in the grinding process2. Workpiece damage in grinding The most notable and severe type of workpiece damage is known as workpiece burn. Burn occurs when enough heat and energy is created by the grinding process to produce discolouration and blemishes which can be seen on the workpiece [1–3]. Workpiece burn, however, can occur even when no physical ﬂaw is observed ...Interpolation optimization for robotic grinding with ...In actual grinding process, the effective grinding area varies along with grinding angle θ. As shown in Figure 7(a), assuming a p is constant, when the abrasive moves from position A to position B, its effective grinding area changes as shown in Figure 7(b). Since end and head face of the abrasive are not able to perform grinding, the grinding ...
