Specific Cutting Energy - an overview ScienceDirect Topics

Specific cutting energy decreased with temperature and was about 6 J/mm 3 compared with 40–100 J/mm 3 in grinding. Therefore, LAM is less likely to induce subsurface damage than grinding. If LAM of ceramic parts could be implemented instead of grinding at typical metal cutting speeds, processing cost reductions of 60–80% could be achieved. Moreover, for silicon nitride and partially ...

Abstract Grinding is a multi-point cutting operation. The specific energy or the energy expended for unit material removal in grinding is very high, typically one or two orders higher than the machining specific energy.
