Question

Page 2 of 3 1. A 2.0-in long. 1-in dliameter aluminum alloy (6061-T6) rod is beling reduced in diameter to 0.750-in by turning on a lathe to produce a bushing for a CNC lathe turret. The part, along with complete dimensions, is shown in Figure 1 Figure : Bshing The part will be cut using a Tormach 15L Slant Pro CNC Lathe. The specifications of the lathe are given Tale : Tormnch 1SL. Slant Pro CNC Lathe Specificutions below Chuck Size: 6 Spindle Power: 3HP Spindie Speed: 100 to 3500 RPM Max Feed Rate: 60 IPMX) 60 IPM (Z) The part will be machined in five steps: (1) Face the part, (2) Turn 1" stock down to 0.9375 along entire length of the part (1.5'), (3) Turn the first 1.25 of part down to 0.750", (4) Chamfer the edge with a 0.050 break, (5) Part off. An external turning tool (PN 33131) and a parting tool (PN 33134). with carbide inserts, will be used to carry out each process. a) Assuming no cutting fluid will be used, select an appropriate spindle and axial speed for the working material. b) Calculate the cutting speed, material removal rate, and cutting time
