1. When a narrow surface is being machined, the cutter should be Larger than the surface. 2. An angular surface may be cut by swiveling the Head to the correct angle or by setting the work in the vise at an angle up to 45 degrees . 3. The cutting speed of a metal will vary depending on the metal's hardness, structure, and Machinability . 4. The formula for calculating the r/min for inch cutters is 4 times the cutting speed divided by the Diameter of the cutter. 5. The formula for calculating the r/min for metric cutters is 320 times the cutting speed divided by the Diameter of the cutter. 6. When a block is being machined square and parallel, there is a definite order in which the sides must be machined. Using the illustration below, place the letter that indicates each side beside the proper numbered side in the left-hand column. Side 1: D Side 2: C Side 3: B Side 4: A 1. When a two-fluted end mill is used to cut a slot, the maximum depth of cut should be a. twice the cutter diameter. b. one-half the cutter diameter. c. one-quarter the cutter diameter. d. the same as the cutter diameter.
2. Which of the following shapes would be produced if the crank were turned 6 full turns plus 14 holes on the 21-hole circle? a. Triangle. b. Square. c. hexagon. d. octagon. 3. The formula used to calculate the angle of a helix is: Tangent of the helix angle = a. lead of helix circumferenceof work b. circumferenceof work lead of helix c. diameterof work lead of helix d. lead of helix diameterof work 4. The formula for the pitch of a rack is a. 3.1416 DP b. DP 3.1416 c. CP 3.1416 d. DP× 3.1416
