Due to its highly mechanical function, there is a tendency for people to think of bone as being inert or less biologically active than the soft tissues of the body. In fact, bone is a highly dynamic tissue that is constantly in a state of remodeling. Bone adapts its structure in response to the loads that it experiences, as described by Wolffs law. Remodeling of bone microstructure is a cell- driven process that occurs...
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...
