In an orthogonal cutting test on mild steel, the following results
were obtained:
Wid h f hi Width of chip = 2.5 mm, Udf d n e ormed chi hi k hip thickness = 0.25 mm,
Chip thickness = 1.0 mm, Working normal rake = -5°
,
Cutting force = 900 N, Thrust force = 600 N
Calculate
The shear angle
The mean shear strength of the work material, in
meganewtons per square metre (MN/m2)
