The following data is available for machining a component on a turret or center lathe: find out the total number of components to be machined to justify the use of turret lathe

Minimum dimensional and form accuracy can be obtained in the cylinder bores of automobile engines if the bores are finished by

Teeth of internal spur gears can be accurately cut in a

In an orthogonal cutting test on the following data were obtained
Uncut chip thickness $$=0.25mm,$$ Cutting speed: $$60m/min,$$ Tool rake angle: $$0$$ Chip thickness $$0.75mm,$$ Cutting force : $$900$$ $$N$$, Thrust force : $$450$$ $$N$$

Calculate the shear angle, total power in making the cut and coefficient of friction between the chip tool interface.
