Question

In In finish machining of an island on a casting with CNC milling machine, and 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 compensation, the trajectory of the cutter will be

• A. (0, -5), (55, -5), (55, 35), (-5, 35) (-5, -5)
• B. (5, 5), (45, 5), (45, 25), (5, 25), (5, 5)
• C. (-50, 0), (-5, 35), (55, 35), (55, -5) (-5, 5)
• D. (5, 5), (5, 25), (45, 25), (45, 5), (5, 5)

Answer 1

The correct option is A (0, -5), (55, -5), (55, 35), (-5, 35) (-5, -5)

Dia of end milling cutter = 10 mm
