1.
Adjust the drill press to the correct speed so the drill bit ________
Correct Answer
A. Will not break
Explanation
The correct answer is to adjust the drill press to the correct speed so the drill bit will not break. This is because using the correct speed ensures that the drill bit is not subjected to excessive force or friction, which can cause it to break. By adjusting the speed appropriately, the drill bit can operate smoothly and safely without the risk of breaking.
2.
Be sure the tapered shank of the chuck or drill is seated in the spindle so it ________.
Correct Answer
B. Will not fall out
Explanation
The explanation for the correct answer is that when the tapered shank of the chuck or drill is properly seated in the spindle, it ensures a secure fit and prevents it from coming loose or falling out while in use. This is important for safety reasons and to maintain the stability and effectiveness of the drilling operation.
3.
__________ leave a chuck key in the chuck socket.
Correct Answer
D. Never
Explanation
Leaving a chuck key in the chuck socket can be dangerous as it can cause the machine to unexpectedly start or the key to fly out and cause injury. It is important to always remove the chuck key from the socket after use to ensure safety.
4.
Never hold small work __________ while drilling.
Correct Answer
B. In your hands
Explanation
When drilling small workpieces, it is important to never hold them in your hands. This is because the rotating drill bit can catch the workpiece and cause it to spin rapidly, potentially causing injury to your hands or fingers. It is safer to secure the workpiece in a drill vise or on a table using a c-clamp to ensure stability during drilling.
5.
Clamp your material to the table or use a drill press vise to keep the drill from __________.
Correct Answer
C. Catching your work
Explanation
To prevent the drill from "catching your work," it is important to clamp the material to the table or use a drill press vise. When drilling, the drill bit can catch onto the material and cause it to spin or move unexpectedly, which can be dangerous and lead to accidents. By securely holding the material in place, the risk of the drill catching and causing damage or injury is minimized.
6.
__________ stop revolving work by grabbing it. Turn off the machine and step away.
Correct Answer
D. Never
Explanation
The phrase "stop revolving work by grabbing it" implies that the machine is in motion and work is being done. The instruction is to turn off the machine and step away, indicating that it is not safe to grab the work while it is still moving. Therefore, the correct answer is "never," as it emphasizes the importance of not grabbing the work while the machine is still in operation.
7.
Ease the pressure of the __________ as the drill breaks through the bottom side of your material.
Correct Answer
A. Feed
Explanation
The correct answer is "feed". When drilling through a material, the feed refers to the rate at which the drill is advanced into the material. By easing the pressure of the feed as the drill breaks through the bottom side of the material, it helps to prevent any damage or splintering that may occur. This ensures a clean and smooth drilling process.
8.
Large drills should be run __________.
Correct Answer
C. At slow speeds
Explanation
Large drills should be run at slow speeds because they have a larger diameter and require more power to rotate. Running them at fast speeds can cause overheating and damage to both the drill and the material being drilled. Additionally, running large drills at slow speeds allows for better control and accuracy during the drilling process.
9.
Drum sanding should be done at no more than __________.
Correct Answer
B. 1200 R.P.M.
Explanation
Drum sanding should be done at no more than 1200 R.P.M. This is because sanding at higher speeds can cause the sandpaper to wear out quickly and may result in uneven sanding or damage to the surface being sanded. By keeping the speed at 1200 R.P.M., the sanding process can be done effectively and safely.
10.
When drum sanding, feed your material in __________ direction the drum is turning.
Correct Answer
A. The opposite
Explanation
When drum sanding, it is recommended to feed your material in the opposite direction of the drum's turning. This is because feeding the material in the same direction as the drum's turning can cause the material to catch or tear, leading to uneven sanding and potential damage to the material. Feeding the material in the opposite direction allows for smoother and more controlled sanding, resulting in better overall results.
11.
When using the drill press, __________.
Correct Answer
C. Do not lean too close to your work
Explanation
When using the drill press, it is important not to lean too close to your work. This is because leaning too close can increase the risk of injury, as the rotating drill bit can catch on clothing, jewelry, or even your body. By maintaining a safe distance from the workpiece, you can minimize the chances of accidents and ensure your safety while operating the drill press.
12.
Mortising, routing, and shaping on the drill press require special equipment and instruction. You should not attempt any of these special operations without proper instruction and __________.
Correct Answer
A. The instructors approval
Explanation
When performing mortising, routing, and shaping on the drill press, it is crucial to have proper instruction and guidance from an instructor. This is because these special operations require specific techniques and knowledge to ensure safety and accuracy. Without the instructor's approval, attempting these operations can lead to improper use of the equipment, potential damage, and even personal injury. Therefore, it is essential to seek the instructor's approval before attempting any of these special operations on the drill press.
