As part of the final step in the manufacture of a key structural part for installation in the 2024 model year Ford Taurus car, the part is machined using two-dimensional cutting with a cutting tool whose rake angle is 7. The following are the data determined during or at the end of the cutting process: (a) cutting speed = 150 m min- (b) depth of cut on the part = 0.25 mm (c) chip thickness = 0.30 mm (d) cutting force = 620 N (e) thrust force = 197 N Calculate the RATIO of the power lost to friction at the tool-chip interface to the total power.
