  8. Lathe Cutting Speeds in Feet and Meters per MinuteUsing a High-Speed Steel Toolbit Krar, S. & Check, A. (1997). Technology of Machine Tools 5th. ed). Glencoe/McGraw-Hill. Waterville, OH.

  9. Rough Cut Finish = .010 to .020Material – Machine Steel RPM = CS x 4 / 3 90 x 4 / 3 = RPM = 120 Krar, S. & Check, A. (1997). Technology of Machine Tools %th. ed). Glencoe/McGraw-Hill. Waterville, OH.

  10. Table 47-1, Page 1 Using the above charts calculate the proper feed and speeds for the following problems using a HSS Tool Bit. • Face off one end of a 2” diameter tool steel shaft, then turn the end of that shaft to a diameter of 1.875 by 5.000 long. Then turn the 1.875 diameter to a diameter of 1.250 by .687 long, on one end of the shaft. Calculate the RPM, for a rough cut process. Show all work. • Face off the end of a .500 tool steel shaft, then turn the diameter to .437 by .750 long. Calculate RPM for a finish cut process. Show all work. Krar, S. & Check, A. (1997).

  11. Table 47 – 1, Page 2 Using the above charts calculate the proper feeds, and speeds, for the following problems using a HSS Tool Bit for all problems. • Face off one end of a 4” diameter Aluminum shaft, then turn the end of that shaft to a diameter of 2.550 by 3.000 long. Then turn the 2.550 diameter to a diameter of 1.9375 by 1.500 long, on one end of the shaft. Calculate the RPM to produce a finish machine process. Show all work. • Face off a 2.250 diameter Bronze shaft, then turn the shaft to a diameter of 1.9375 by .9375 long. Next turn the 1.9375 diameter to a new diameter of 1.375 by .750 and produce a finish machine process. Show all work. Krar, S. & Check, A. (1997). Technology of Machine Tools 5th. ed).
