Case study II The components in Figure 1 include the two gears used to adjust the inclination of a bucket seat in an automobile.
Case study IIThe components in Figure 1 include the two gears used to adjust the inclination of a bucket seat in an automobile. The smaller gear is approximately 1 inch in diameter, and the large, flat gear has a diameter of 2.25 in. Both have been machined from steel (by labor-intensive hand machining) to produce prototypes for testing a new design. Based on that prototype, your company, Progressive Seating, has been awarded a contract to provide the seats for a major automotive manufacture. You now need to move into mass production. Based on the prototype and laboratory testing, your design team has specified a minimum tensile strength of 110 Ksi., with a surface hardness in excess of Rockwell-C 25.Figure 1While the prototype gears were machined from round steel bars, you are free to specify any material or method of fabrication that will provide the required properties. While it appears desirable to retain some form of ferrous metal, your design team is suggesting manufacture by powder metallurgy. (a)
