Determine shear plane angle, Mechanical Engineering

Assignment Help:

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 -

(a)Various energy consumed (b) Frictional force and friction angle

(c) Shear Plane angle.
