Not illustrated. 1910 Excerpt: ...of and ffy respectively for roughing and finishing. Find the time required to complete the work, using 1f" stock. 17. A lot of 16 spindles, 15 " long, are to be turned down from 2" to 1" in diameter for 15" of their length. How long will it take with a cutting speed of 40 ft., a feed of (roughing) and 5ff" (finishing), and a depth of cut not to exceed /5"? 18. Estimate the time necessary to finish the crank shown in Fig. 74. Owing to the opening between the arms, either a low cutting speed or a light cut must be used. 19. A taper ring-mandrel " at the small end and 1" at the large end is turned from a 1f" round bar. Estimate the time required to do the work if the surface speed employed is 40 ft. a minute, the feed?J5," and the depth of cut does not exceed 335." 20. Estimate the time required to make the phosphorbronze bearing shown in Fig. 75. Time must be allowed for setting the taper attachment and setting for the thread. 21. If a milling cutter revolves 85 times per minute with a table feed of G" per minute, what is the feed per revolution? What is the feed per tooth with a 10-tooth cutter? 22. A cutter revolves at 203 K. P. M. with a table feed of per minute. Find the cutting speed for a f" end mill and the cutting speed 25 ft. a minute. Find the weight of metal removed per hour. 24. If an end mill 1" in diameter has 12 teeth and is to mill a surface 4" x 16," using the end of the mill, find the K. P. M. and the total time required. Assume a cutting speed of 40 ft. per minute and a feed of.004" per tooth. 25. An end mill is in diameter and has 6 teeth. Find the number of revolutions necessary to give the mill a surface speed of 40 ft. a minute. 26. Find...
