Description
Summary:Quantitative relationships between the cutting conditions (speed and feed) and the performance criteria (tool wear and surface finish) are concerned. A computer numerical control drilling and tapping machine are used in the 380 aluminum alloy tests with the high-speed M7 steel drills. It is inferred that when the cutting speed was doubled from 195 to 390 ft/min (99 to 198 cm/s), the drill wear increased 50% and only 7% when the feed rate was increased from 0.016 to 0.032 in./rev (0.406 to 0.812 mm/rev). A 16% and 15% rise in surface roughness was associated with increasing the cutting speed from 195 to 390 ft/min and the feed rate from 0.016 to 0.032 in./rev, respectively.
