Book: Technology of machine tools workbook (7th edition)

Decide whether each statement is true or false and circle the letter in the right-hand column that indicates your choice. The cutting speed of a metal is stated in in/min. In order to get a fine surface finish, you should increase the speed of the cutter. Always use a brush to clean away cuttings. The milling-machine arbor has a self-holding taper. The addendum is the distance from the outside diameter to the pitch circle. The outside diameter of a gear is equal to the number of teeth plus two divided by the pitch diameter. When the head is being aligned on a vertical milling machine, the indicator should be mounted on a rod held in a chuck. When indicating the head, swivel it the amount of difference in the readings on the dial indicator taken at the front and back of the table. When aligning the vise, tap it so that the parallel moves away from the indicator. When machining a keyseat having two blind ends, use a two-fluted end mill.

Solution
