STATEMENT IS TRUE OR FALSE

Greater the anisotropy ratio, the higher Is the deep drawability of the shoot metal. In deep drawing of cylindrical cups, the stresses in the flange area are responsible to cause punch-through type fractures due to wrinkling (buckling) in the early stage of deep drawing. In orthogonal cutting of metals, there are two rake angles for the same shear angle and the same cutting ratio. The cutting fluid in machining has influence on shear angle, cutting ratio, and chip thickness. Shear angle increases with increase in rake angle, whereas; shear strain decreases with decrease In rake angle. Most of the heat produced In machining operations goes Into the work piece and the least goes into the cutting tool. Two cutting speeds are possible which produce the same tool life. In grinding process, the most important parameters are the friability of abrasive grain and the bond strength between grains. Crater wear in machining is due to tool chip interface friction. In grinding, the grit makes a positive rake angle and shear angles are always negative.

Solution

1. true

as the aninstropy is respobile for the deep drawing

2. true.

3.false

4. false

the coolant does not have any effect in the geometrical properties of the metal. it only removes the excess heat
