Question

Outline of a machined part is shown in Figure Q 6. The pa mill of diameter 32 will be used for clamping during millinghien speed is 130 m/min, and teed 001 mm/tooth. Use the lower left corner at the top surface o Postprocessor call statements for profile milling For this part: rt has to be profile milled using end mm having four teeth. The holes in the part are previously machined and ng the part during milling. Thickness of the part i mm. Cutting f the part as the origin in the coordinate system. are MACHIN/MILL, 06 Define the APT geometry statements for all relevant elements (points, lines, circles and planes) including the target point. All the above geometry elements are to be definedat a reasonable distance below the bottom surface of the part to ensure complete machining of the side surfaces. Consider that the end mill has a 2.6x2.6 mm chamfer at its boom end. Write complete APT motion statements to profile mill the outer edges of the part.Postprocessor call statements for profile milling is MACHIN/MILL, ii. 05 10 dia. 2 holes 25 5 P3 4 12 dia. . 1 hoie P4 6 P9 25 rad P10 C1 L3 P2 25 rad 100 P5 3 dia 3 holes 75 P11 E0 P8 25 L1 Po 25 75 100 150 200 Fig. Q6
