During turning process with 7-a-6-6-8-3-1 mm (ASA) tool the underformed chip thickness of 0.2 mm and width of cut of 2.5 mm were used. The side rake angle of the tool was a choosen that the machining operation could be approximated to be orthogonal cutting. The tangential cutting force and thrust force were 1177 N and 560 N respectively. Calculate:

  1. The side rake angle
  2. Coefficient of friction at the rake face
  3. The dynamic shear strength of the work material.
