6) Assume that an operator is drilling with holes, equally spaced in a bolt-hole circle, i.e., there would be holes at 12, 3, 6, and 9 o'clock and four more holes equally spaced between them. The diameter of the bolt hole circle is 6 in. The designer says that the holes must be 45 ± 1° from each other around the circle. a) Calculate the tolerance between hole centers (Hint: units should be inches). b) Could a typical multiple-spindle drill setup be used to make this bolt circle - using eight drills at once? Why or why not? c) What is a jig? Would using one be beneficial for the operator?
