Q5) If the spirit level used for testing the parallelism of the ways of the turning machine reads .4 mm. a) Show what the spirit value means? b) If the ways of the turning machine show lack of parallelism, how this can affect the workpiece?

! Required information Sally is making a sine bar, which is used to machine angles on parts (see the given figure). She has a 1.250-inch-thick bar that needs 90° grooves machined into it for precision ground 1.0000-inch 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 D = 5.6 inches. NOTE: This is a multi-part question. Once an answer is submitted, you will be unable to return to this part. -1.0000 Ø 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? (Round the final answer to four decimal places.) The required thickness is inches.

How many cutting-plane lines are shown on this print?

Write the NC part program for the part. Holes are threaded and requires two tools; T1 is a 0.5" HSS drill bit and T2 is a 0.5" tapping bit. The rest of the features are cut using a 0.75" HSS milling tool, T3. Feed rate and spindle speed are 10 ipm and 2000 rpm. The material is low- carbon steel. Part thickness is 0.5”. Use dotted lines two show the path of tools movements. Set up proper operation conditions as discussed in the class today.
