In a $$2-D$$ $$CAD$$ package, clockwise circular arc of radius, $$5,$$ specified from $${P_1}\left( {15,10} \right)$$ to $${P_2}\left( {10,15} \right)$$ will have its center at

In finish machining of an island on a casting with $$CNC$$ milling machine, an end mill with $$10$$ $$mm$$ diameter is employed. The corner points of the island are represented by $$(0,0), (0,30), (50,30)$$ and $$(50,0)$$. By applying cutter radius right compensation, the trajectory of the cutter will be

A cylinder of $$155$$ $$mm$$ is to be reduced $$150$$ $$mm$$ diameter in one turning cut with a feed of $$0.15$$ $$mm$$/ revolution and a cutting speed of $$150$$ $$m/min$$ on a $$NC$$ lathe. What are the programmed spindle speeds programmed feed rate, and the material removal rate?

In a point to point control $$NC$$ machine, the slides are positioned by an integrally mounted stepper motor drive. If the specification of the motor is $$1$$ deg/pulse, and the pitch of the lead screw is $$3.6$$ $$mm,$$ what is the expected positioning accuracy?
