A drill bit during its lifetime can produce 150 through holes in a plate at a drill-speed of 200 RPM. If the drill-speed increases to 300 RPM, then it can produce 60 through holes in the same plate before the drill bit f...
Taylor's tool life equation is used to estimate the life of a batch of identical HSS twist drills by drilling through holes at constant feed in 20 mm thick mild steel plates. In test 1, a drill lasted 300 holes at 150 rp...
Two cutting tools with tool life equations given below are being compared: Tool 1: VT^0.1 = 150 Tool 2: VT^0.3 = 300 where V is cutting speed in m/minute and T is tool life in minutes. The breakeven cutting speed beyond...
