摘要

In this study, the performances of the WC tools coated with TiCN and AlCrN by filter cathodic arc in hole drilling of forging brass were investigated and compared with that of uncoated one. The performances were evaluated using the exit burr height (EBH) criterion and process capability indices as a function of number of parts drilled with the three types of drills. The results showed that there were significant differences of EBH and the process capability index of Cpm during drilling of the workpieces with the three types of drills. The desired EBH values of 0.152-0.1535 mm, roughness values of 2-3 mu m and drilled diameters of 17.79-17.8 mm were achieved with the appropriate operating conditions including cutting speeds and feed rates ranging from 0.17 to 0.19 mm/rev and 55 to 57 m/min, respectively.
