The following data was obtained from an orthogonal cutting test :
Rake angle = 20o, Depth of cut = 6 mm
Feed rate = 025 mm/rev
Chip length before cutting = 29.4 mm
Chip length after cutting = 12.9 mm
Vertical cutting force = 1050N, Horizontal cutting force = 430N
Using Merchant analysis, Evaluate -
