Higher grinding forces have harmful impact on service life of grinding wheel and surface integrity of workpiece. Large supply of cutting fluid is often used to lower grinding force by improving lubrication condition, but it will cause various environmental threats. In this paper, an engineered grinding wheel (EGW) bio-inspired by phyllotaxis was developed to lower grinding forces with eco ...
