An orthogonal operation is carried out at $$20m/min$$ cutting speed, using a cutting tool of rake angle $$15deg$$. The chip thickness is $$0.4mm$$ and uncut chip thickness is $$0.2mm.$$

The chip velocity (in $$m/min$$) is

The total angular movement (in degrees) of a lead screw with a pitch of $$5.0mm$$ to drive the work table by a distance of $$200mm$$ in a $$NC$$ machine is

A titanium sheet of $$5.0mm$$ thickness is cut by wire cut $$EDM$$ process using a wire of $$1.0mm$$ diameter. A uniform spark gap of $$0.5mm$$ on both sides of the wire is maintained during cutting operation. If the feed rate of the wire into the sheet is $$20mm/min,$$ the material removal rate (in $$m{m^3}/\min $$) will be

Anisotropy in rolled components is caused by
