Multiple choice

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 centre to machine the island PQRS is

  1. (- 8, - 8), (108, - 8), (108, 58), (- 8, 58), (- 8, - 8)

  2. (8, 8), (94, 8), (94, 44), (8, 44), (8, 8)

  3. (- 8, 8), (94, 8), (94, 44), (8, 44), (- 8, 8)

  4. (0, 0), (100, 0), (100, 50), (50, 0), (0, 0)
