What are coolants used for?
-
Lubricating the cutter face
-
Flushing away the chips
-
Reducing frictional heat to extend the life of the cutter's edge
-
All the above
Correct Answer
A. All the aboveExplanation
Coolants are used for multiple purposes in machining processes. They lubricate the cutter face, which helps in reducing friction between the cutter and the workpiece. They also flush away the chips produced during cutting, preventing them from interfering with the cutting process. Additionally, coolants reduce frictional heat generated during cutting, thereby extending the life of the cutter's edge. Therefore, the correct answer is "All the above."Rate this question:

-
Arbor support-the casting that slides in dovetail ways on top of the column.
-
Arbor support-the casting that contains a bearing that aligns the outer end of the arbor with the spindle.
-
Arbor support-the casting that supports table and saddle
Correct Answer
A. Arbor support-the casting that contains a bearing that aligns the outer end of the arbor with the spindle. -

You should consider which of the following when determining the proper cutting speed
-
The harder and tougher the material being cut the slower the cutting speed should be
-
The harder and tougher the material being cut the faster the cutting speed should be
-
None of the above
Correct Answer
A. The harder and tougher the material being cut the slower the cutting speed should beExplanation
When determining the proper cutting speed, it is important to consider the hardness and toughness of the material being cut. Harder and tougher materials require slower cutting speeds because they are more resistant to cutting and can cause excessive wear on the cutting tool if the speed is too fast. Therefore, the correct answer is that the harder and tougher the material being cut, the slower the cutting speed should be.Rate this question:

The most common milling cutters are
-
Plain milling cutters
-
Angular milling cutters
-
Face milling cutters
-
Forming cutters
-
All the above
Correct Answer
A. All the aboveExplanation
The correct answer is "All the above" because all of the mentioned milling cutters are commonly used in milling operations. Plain milling cutters are used for removing material from the surface of a workpiece, angular milling cutters are used for creating angular surfaces or grooves, face milling cutters are used for milling flat surfaces, and forming cutters are used for creating complex shapes or contours on the workpiece. Therefore, all of these options are correct.Rate this question:

When machining squares or hexagons which 2 cutters will you most often use?
-
Angle and face milling cutters
-
Half-side and side milling cutters
-
Side and end milling cutters
Correct Answer
A. Side and end milling cuttersExplanation
When machining squares or hexagons, the most commonly used cutters are side and end milling cutters. Side milling cutters are used to remove material from the side of the workpiece, while end milling cutters are used to remove material from the end or face of the workpiece. These two types of cutters are ideal for creating the flat surfaces and precise angles required for squares and hexagons. Angle and face milling cutters are not typically used for machining squares or hexagons, and half-side and side milling cutters are not commonly used for this purpose either.Rate this question:

In any Indexing operation NEVER start counting from the hole adjacent to the crankpin
-
True
-
False
Correct Answer
A. FalseExplanation
The statement is false because in indexing operations, it is common practice to start counting from the hole adjacent to the crankpin. This is done to ensure accurate positioning and alignment of the indexing mechanism. Starting from the adjacent hole allows for precise and consistent indexing movements, resulting in more reliable and efficient operations.Rate this question:
