4. Given the following for a carbide insert single point tool, what is the expected tool life for a high-speed operation given: . = 257.35 b. Vc = 10 m/sec c. So = 1mm/rev d. T = 3mm e. y = 0.2 (Experimentally derived) f. z = 0.198 (Experimentally derived) 1 ; n = 0.5 g. x == ; n = n 5. Changing the type of insert from Q.4, reference the table below to calculate the tool life with a high-speed steel insert. Range of n values for various cutting tools High Speed Steels Cast Alloys Carbides Ceramics 0.08-0.2 0.1-0.15 0.2-0.5 0.5-0.7 Assume n = 0.2 value and a new speed of 100m/s and a depth of cut of 8mm.
