Prediction of Forces in Micro-Cutting and the Study Based on Simulation
In micro-cutting process, a remarkable characteristic of micro-Cutting is that cutting parameters level closing to the crystal grain msize of material. Though, the prediction formula of micro-cutting forces should reference to strain gradient plasticity theory in formula construction , while cutting edge radius had been regard as a important parameters in the process of micro-cutting. With advantedge FEM software for simulation of micro-cutting , the results show that, there was no significant effect of temperature on cutting force; strain gradient reaction will be decreased by feed rate’s reducing in process, cutting depth effected cutting force in linear mode, the max. workpiece temperature area is no longer the second deformation area but the primary deformation zone, while the max. temperature area of the tool would transfer to the tool tip from theoretical location of traditional cutting.
