Investigations at the Cranfield University’s School Of Industrial and Manufacturing Science have demonstrated that HEDG (High Efficiency Deep Grinding technology) can be more competitive than traditional grinding. The three-year investigation culminated in a series of tests on a Cinetic Landis LT2(PDF) High efficiency deep grinding with very high removal,,High removal rates in HEDG are associated with very efficient grinding and very low specific energy compared to conventional grinding. Although HEDG-enabled machine tools are available, the wider,Energy and temperature analysis in grinding,absence of thermal damage can be achieved. HEDG can achieve low specific grinding energy compared with shallow grinding and creep grinding. The chips take away most of the heat generated in the grinding process. As in creep grinding, bum-out of the coolant causes a steep rise in contact temperature of the workpiece. 1 Introduction
