48. Calculate the speed (RPM) and feed (inches per minute) for a milling an aluminum workpiece with a 12 tooth, 4.5 inch diameter cutter using a chip load of 0.012 inches and a cutting speed of 200 SFPM. RPM = IPM= 49. What is the taper per foot of a taper with a large diameter of 1.6 inches, a small diameter of 1.2 inches, and a length of taper of 5 inches? TPF= 50. How would you divide a workpiece into 22 equal divisions using the simple indexing method on a universal dividing head? Hole circles available are: 21-23-27-29-31-33. turn(s) plus hole(s) on the hole circle 51. Calculate the indexing necessary to produce an angular move of 25 degrees 40 minutes (2540') using a standard dividing head. Hole circles available are the same as before: 21-23-27-29-31-33. turn(s) plus hole(s) on the hole circle 48.
