Material Fracture Character of Marble Processing by Single Diamond Tools

Article Preview

Abstract:

Material fracture character of marble processing by single diamond tools was studied by single diamond indentation experiment and fast milling experiment. The surface morphology and inner cracks were achieved based on double lights transmission of stereomicroscope, marble semitransparent character and SEM technology. Results showed Indentation cracks break crystal or extend along cleavage plane from three directions. The marble indentation fracture progress could be divided into three phases: plastic deformation, fracture deformation and block broken. Material broken types were diverse for different compositions in marble.
