5.3: GRINDING FORCES, POWER, AND SPECIFIC ENERGY

5.3 GRINDING FORCES, POWER, AND SPECIFIC ENERGY. Forces are developed between the wheel and the workpiece owing to the grinding action. For plunge grinding operations, as illustrated in Figure 5-2 for straight surface and external cylindrical grinding, the total force vector exerted by the workpiece against the wheel can be separated into a tangential component F t and a normal component F n.

Experimental investigations on surface grinding of silicon

The grinding of Si 3 N 4 ceramics is difficult due to their inherent hardness, brittleness, and machining-induced damages. The effects of environmentally friendly mono and hybrid nanofluids are investigated on grinding forces, specific grinding energy, grinding force ratio, surface integrity and surface/sub-surface damages during grinding of Si 3 N 4 ceramics.

Specific Cutting Energy an overview | ScienceDirect Topics

The maximum grinding power in steady grinding after subtracting the no-load power and the power required to accelerate the grinding fluid has a mean value of 2 kW (or 2.68 hp). The removal rate is 50 mm 3 /s (or 0.183 in. 3 /min). What is the specific grinding energy? e c =2000/50=40 J/mm 3 (or 14.7 hp min/in. 3)

Grinding force and energy modeling of textured monolayer

In the current study, the specific grinding energy gradually increases during the wheel wear process on the condition of v s = 30 m/s, v w = 3 m/min, a p = 0.02 mm . At the initial stage, the specific grinding energy e s increases with a decreased variation rate.
