Abstract: The single-edge single-grit orthogonal cutting model was developed, and the finite element simulation of micro mill-grinding was accomplished using the arbitrary Lagarangian Eulerian (ALE) method. The distribution and variation of temperature fields in the cutting process were analyzed. For the grinding of abrasive grains on the rear face, its effect on processing temperature was investigated. Temperature zones were defined according to the heat sources distribution, and the temperature change law of each temperature zone was analyzed. The simulation results show that the maximum temperature during processing is located at the abrasive grinding zone and the zone adjacent to the cutting edge. The temperature change law of each temperature zone in micro mill-grinding is the same as that in micro milling except for abrasive grinding zone. Grinding of the grit on rear face leads to temperature rise of all zones during processing. And the closer from the grinding zone, the larger the temperature rise is.

Key words: micro mill-grinding, orthogonal cutting, single-edge single-grit, finite element simulation, temperature
