in the examples of a computerized drilling machine that were presented in your reading material, downward movement of the drill bit toward the metal plate was in the
a. positive direction of the x axis
b. neg. direction of the x axis
c. neg. direction of the y axis
d. neg. direction of the z axis
Hey, how would we know the particular coordinate system used by your drill press ?
Chances are it is negative z
To answer your question, let's break it down:
1. First, determine which reading material you are referring to that mentioned examples of computerized drilling machines. Look for the specific source or document where you found this information.
2. Review the reading material and identify the section that explains the examples of computerized drilling machines. Look for any diagrams, descriptions, or specifications that discuss the movement of the drill bit.
3. Pay attention to any details provided about the downward movement of the drill bit towards the metal plate. It may be explicitly mentioned whether the drill bit moves downward or not. Consider any information related to the drilling mechanism or the function of the machine.
4. Take note of any specific terms or phrases used in the reading material to describe the movement of the drill bit. Look for words like "downward," "vertical," "plunging," or other indications of the direction of the drill bit's movement.
Once you have carefully reviewed the reading material and considered the factors mentioned above, you should be able to find the answer to your question regarding the downward movement of the drill bit toward the metal plate in the examples of computerized drilling machines.
