Question

You are required to write a part program that will make an end mill cut the curved slot shown below. The end mill should enter the slot at point (x,y) = (5 in, 0 in), cut with a depth of cut = 0.1 in until point (x,y) = (-5 in, 0 in), and cut with a depth of cut = 0.1 in back to (x,y) = (5 in, 0 in). The feed = 20 in/min and the spindle speed = 1000 rpm. The radius of curvature of the center line of the slot is 12 in. Assume the tool has a diameter equal to the width of the slot.
Multiple choice. Select only one true alternative. You are required to write a part program that will make an end mill cut the curved slot shown below. The end mill should enter the slot at point (x,y) = (5 in, o in), cut with a depth of cut = 0.1 in until point (x,y) = (-5 in, 0 in), and cut with a depth of cut = 0.1 in back to (x,y) = (5 in, o in). The feed = 20 in/min and the spindle speed = 1000 rpm. The radius of curvature of the center line of the slot is 12 in. Assume the tool has a diameter equal to the width of the slot. -5 in, 0 in 5 in, in X Note: The plane of the figure is at height z = Q. Cut into the page. Inspect, very carefully, the G-code alternatives below. Choose the one that matches all the requirements of the operation.

Answer 1

Sol”; да (sin, oin) f5in, oin) x Given: The end mill should enter the slot at Point(x,y)=sin,oin), cut with a depth cut = 0.1 in until Joint(x,y)=(-51n, oin), and cut with a depth of aut = 0.1 in back to (24, y) =(Sin,oin). The feed = 2oin/min and the spindle speed = 1000rpm. The radius of Curvature of the center line of the blot is 12 in. Assume the tool has a diameter equal to the width of the slot.
