The function of interpolator in a $$CNC$$ machine controller is to

During the development of a product, an entirely new process plan is made based on design logic, examination of geometry and tolerance information. This type of process planning is known as

A drill is positioned at point $$P$$ and it has to proceed to point $$Q.$$ The coordinates of point $$Q$$ in the incremental system of defining position of a point in $$CNC$$ part program will be

For machining a rectangular island represented by coordinates
$$P(0,0), Q(100,0), R(100,50)$$ and $$S(0,50)$$ on a casting using $$CNC$$ milling machine, an end mill with a diameter of $$16$$ $$mm$$ is used. The trajectory of the cutter center to machine the island $$PQRS$$ is
