Taper Problems III

1. Calculate the offset required to turn a taper 8.000 long if the difference in diameters of the ends is equal to .463.

2. Calculate the offset required to turn a B&S taper 18 .000 long.

3. The diameters at the ends of a taper 12.0 long are 2.003 and 1.752. Compute the tailstock offset required to turn the taper.

4. Compute the offset of the tailstock required to turn the following Jarno tapers: #10, #12, #9, and #15.

5. Compute the offset required to turn a B&S taper on work of the following lengths: 9 in., 14 in., 15 in., 16 in., and 12.5 in.

6. Compute the offset required to turn a Morse #4 taper in the following lengths. 9 in., 14 in., and 12 in.

7. Suppose the tailstock of a lathe is offset 5/16 in. and tapers are cut on pieces of work 10 in. long and 14 in. long. Find the taper per foot on both pieces.

8. The same taper per foot is to be turned on two pieces of work whose lengths are 8 in. and 10 in. If the tailstock is offset 3/16 in. to turn the 8 in. piece, how much must the offset be increased or decreased to turn the 10 in. piece?

9. Calculate the offset required to turn a taper of 3/4 in. per foot on a work piece that is 18 in. long

10. Account for the presence of the 2 in the formula for calculating the offset of the tailstock of a lathe.

11. In calculating the offset of the tailstock to turn a taper, the total length of the work is substituted in the formula. Would there be any objection to substituting the length of the work measured along the surface? Why?

12. Calculate the offset required to turn the following part.

13. Compute the offset required to turn the taper shown in the following drawing.

14. If the tailstock offset is 1/8 in. what taper will be turned on a piece of work 10 in. long? On a piece of work 14 in. long?

15. The pulley shown in cross section is turned to a diameter of 5 in.. It is then crowned with a taper of 1/4 in. per foot. If the pulley is mounted on a mandrel 5 and 1/4 in. long calculate the offset of the tailstock.
