摘要

Drilling is considered as a complex three-dimensional cutting process involving variations in cutting speed and rake anglernalong the cutting edge. The present paper investigates the effect of cutting parameters on chip morphology characteristics,rnchip compression ratio and its micro-hardness during dry drilling of austempered ductile iron (ADI). The chip morphologyrncharacteristics were examined using an optical microscope and a scanning electron microscope (SEM). Shear induced lamellarnstructure was observed at the chip-free surface at higher cutting speed. Chip micro-hardness and chip compression ratiorn(CCR) values were calculated for all cutting conditions to investigate the influence of cutting parameters on plasticrndeformation of ADI during its transformation to chips. The obtained results show good relationship between the chip microhardness,rnCCR, cutting parameters and chip morphology.
