Wear Experimentand Reserch of Poly crystalline Diamond Tools on SiC/SiC Composite Milling under Cryogenic Cooling Condition
Polycrystalline diamond(PCD)tools were used to mill SiC/SiC composite under dry and cryogenic cooling conditions,obtaining wear morphology of the rake and flank surfaces on the PCD tool.The wear modes of the PCD tools were analyzed,and the tool service life was measured.The reserch results show that the major wear modes of the PCD tools are tool nose fracture and edge tripping under the dry milling condition,while the major wear modes are tool nose fracture and spalling under the cryogenic cooling condition.To compare with the PCD tool under the dry cutting condition,the usage life of the PCD tools under the cryogenic cooling condition increases up to 71.4％.
