02: A bar of 60 mm diameter and length of 3 meter is used to produce 500 pieces on a center lathe having the following characteristics: . Maximum rotational speed .Minimum rotational speed .Number of speeds Lathe overall efficiency The turning process is performed at 40 m/min cutting velocity. 0.5 mm/rev longitudinal feed, 0.25 mm/rev transverse feed and 2 mm depth of cut REQUIRED 1. Calculate the TWELVE rotational speeds in rpm. 2. What rotational speed would you choose? 3....
Question 1 A turning operation is carried out on aluminum. Based on the specific energy values in Table 20.2, determine material removal rate and cutting power in the operation under the following sets of cutting conditions: (a) Cutting speed 5.6 m/s, feed 0.25 mm/rev, and depth of cut 2.0 mm; and (b) cutting speed- 1.3 m/s, feed 0.75 mm/rev, and depth 4.0 mm. Question 2 Consider a turning operation performed on steel whose hardness 225 HB at a cutting speed...
