Place the correct word(s) in the blank space(s) provided at the right-hand side of the page that will make the sentence complete and time. A 3.500-in.-diameter high-speed steel cutter should revolve at r/min to cut aluminum (700 CS) efficiently. The distance from the bottom of the tooth to the pitch circle is called the When setting up to cut a gear, place the end of the mandrel on the indexing-head center. When you are face milling and more than one pass is required, the machined surface will be if the head is not aligned. Before taking a cut on the vertical milling machine, be sure to tighten the clamp. Remove all before setting the workpiece in a vise. In order for the workpiece to be seated properly on parallels, in a vise, feelers should be placed under each corner. Using the information given, calculate the dimensions listed in the right-hand column and place your answer beside each. A gear has a diametral pitch of 8 and a pitch diameter of 5 in.

Solution

26. The distance between the pitch circle and the bottom is called addendum.

27. Place the large end of the mandrel toward the indexing head during cutting.

29. For verticular milling machines, Slot clamps are used to hod the job pieces. Always tighten the slot clamp before giving the cut.

32. Number of teeth = diametral pitch x diameter = 8x5= 40 teeth.

Diametral pitch has the units of tooth/inch.
