Q For this assignment, we will be creating an edge feature to the workpiece. Complete the following: 1. Draw a toolpath on the drawing below that will allow the tool to create the feature shown. 2. Label the endpoints of the lines and arcs for both the actual geometry (A,B,C…) and offset toolpath (A’,B’,C’…) points. 3. Calculate and tabulate the coordinates of the offset toolpath points. 4. Calculate and tabulate the coordinates of the actual points of the geometry. 5. Write programs that will cut this geometry in two different ways. (1). do not use the code of diameter compensation (G41/G42) (2). do use the code of diameter compensation (G41/G42). Parameters are listed below: Work coordinate: G54 Tool number: 4 (dia. 0.5 in.) Depth of cut: 0.1 in. Feed rate: 12 in/min Spindle speed: 800 rpm The Homework should be typed and printed 3.0 3.0 (0,0) 3.0 0.1 R0.25 typ 0.100 typ
