4. tests are performed to determine the tool life of a high speed steel single edge cutting tool. at a cutting speeds (v) of 180 m/min and 110 m/min the corresponding tool life is 4.25 min and 35 min., respectively. except for the cutting speed, the cutting conditions for the test are the same. calculate the value of n in the taylor tool life equation. answers are rounded to three (3) decimal place (x. xxx). (a) 0.234 (b) 1.263 (c) 0.199 (d) 0.492 (e) none of the above
