The grinding ratio G, which is the most important parameter to evaluate the performance of grinding wheel, is given by G = V w ′ π d s Δ R where V w ′ is the cumulative stock removal per unit wheel width, d s is the wheel diameter and ΔR is the radial wheel wear. Moreover, the normal and tangential grinding forces are measured with the ...

Just started assembling my SO3, and I have a question about the eccentric nuts and the v-wheels on the Y-axis. It says the gantry should move freely, without binding, grinding, etc. When I tighten down the eccentric nuts at the bottom of the Y rails, it gets pretty tight. I would say it moves "smoothly", but definitely not "freely".

The multivariate linear regression method is used to obtain the multivariate linear functions of surface roughness, efficiency, and grinding wheel life regarding the grinding parameters (Equation (3)): where 500 ≤ ng ≤ 4000 500 ≤ n g ≤ 4000, 0.1 ≤ T G ≤ …

A measure of the ability of a grinding wheel to remove material is given by G-ratio. An efficient hard wearing grinding wheel will grind an easy-to-grind material for a long time with only a small amount of wheel wear. This corresponds to a high G-ratio. The grinding ratio G is defined as volume of material removed divided by volume of wheel wear.

The volume of the grains can be expressed as: (2) V G = V G/mm 2 ⋅ l c ⋅ a p where V G/mm 2 is the volume of grains per mm 2. Using a digital fringe projection system, the average grain protrusion of the active grains P G of the standard grinding wheel used in this study was determined to 140 μm and V G/mm 2 to 0.0318 mm 3 /mm 2.
