MET 107 Test 2

Saw blade gage is: Blade Thickness Blade length Set Pitch

Saw blade pitch is: Total number of teeth on the blade The amount of set A blade coating design to provide better cutting The number of teeth oer inch

The capacity of the forizontal blade cutoff machine is determined by the: Total length of the blade Largest piece pf square material that can be cut Weight capacity of the roller stock Largest piece of round material that can be cut

If the set is gone on one side of a saw blade, the blade will: Not cut at all Drift in the direction of the side without the set Drift in the direction of the side with the set Cut only one half as fast as if it had set on both sides

What is the tooth spacing in inches of a 16 pitch saw blade? 1/16 (.0625) 1/32 (.03125 1/8 (.125) 1/64 (.015)

Cutting speed is generally: Fast in tough, hard materials Slow in soft materials Fast in soft materials and slow in hard materials The speed that produces blue chips

Recommended feed pressure should be determined by: Experimentation Using a longer pusher Counting the teeth in the band and multiplying by five Conculting the job selector

A fine pitch blade should be used for material that is: Thin Thick Hard Soft

Assuming that a drill press operator has selected the proper tool, safety, clampe his workpiece, what other considerations should he make before starting the drill pess? Make sure he as his foreman's consent Set up the correct speed and feed; select a cutting fuid Get lubricating oil, turn on machine and make a chip; if it is long and blue, the feed and speed are jus tright Consult a drill feeed chart and set the drill rpm, then calculate the reed per revolution

If the drilling speed is too low for the diameter of the drill and the material being drilled: The margins or outter corners are broken down More feed is required to get the drill to cut thus breaking the drill Chips become jammed in the flutes The cutting edges become dulled

When using a sensitive drill pr, you can tell if the feed is approximately right in soft steel if the: Chips come out long and stringy Chips come out blue or violet in color Chip is in short segments Chip is a tightly rolled helix

Jamming of drills, when drillg deep holes, can be avoided by using a procedure called: Alternating Pecking Withdrawal Chipping

The depth stop on a drill press is used for: Keeping the quill from falling out by stopping i at full depth Limiting its stroke and thus preventing the drill from drilling the table Alerting the operator by ringing a bell when he drilling tool is approaching the depth where it would stop Detecting when the drill has stopped cutting; it then shuts off the machine

An angular, odd shapedworkpiece cannot be mounted satisfactorily on the drill table or in a vise. It has one machined surface and the hole to be drilled must be parallel to it. How can this work be set up? Clamped into V-blocks Clamped on an angle plate A special fixture would have to be made There is no way to clamp it, so you would have to hold it with your hands

It is sometimes a good idea to start a tap with a drill press since: You can put a lot of force on the tap with the drill press feed handle If you ger tired turning the tap by hand, you can always turn on the machine All of the above
