Sally is making a sine bar, which is used to machine angles on parts (see Figure 4.19). She has a 1.250 in. thick bar that needs 90° grooves machined into it for precision ground 1.0000 in. diameter cylinders. A sine bar is used by placing different thicknesses under one of the cylinders so that the proper angle is attained. Sally wants the distance between the centers of the cylinders to be 5.000 in.
(a) How deep should she mill the 90° grooves so that the top of the sine block is 2 in. tall?
(b) Once her sine block is finished, she wants to mill a 22.5° angle on a brass block. What thickness of gage blocks will produce this angle for this sine plate?
