| Abstract: | By developing single fracture to Continuous fracture, the times of fracture was counted using k1 the ratio of the area of surface morphology to projected area.The theoretical model of cutting temperature for brittle materials was built based on the conservation of energy of micro-fracture mechanism of cutting Brittle Materials.The theoretical model was verified through turning fluorophlogopite ceramics with carbide tool, and turning experiment is carried out.The results indicate that by using the theoretical model of cutting temperature for brittle materials, variation trend of cutting temperature drived by machining conditions is predictable within limits. |
