Please tell me if this is correct:
14. Which type of machine has a rotating tool cutting motion and a linear tool feed motion?
a. milling machine
b. drill press
c. wood lathe
d. scroll saw
A?
A milling machine has a rotating tool bit. The table moves in the x and y directions, linear. Your answer is correct.
Note that they carefully said WOOD lathe where you can move the bit all kinds of ways with your hand. With a metal lathe the bit is usually constrained to move back and forth especially if cutting threads.
Yes, you are correct! The type of machine that has a rotating tool cutting motion and a linear tool feed motion is a milling machine.
To arrive at this answer, you can examine the options provided and analyze the characteristics mentioned in the question.
a. Milling machine: A milling machine has a rotating cutting tool (usually a drill bit) and a linear tool feed motion, making it a viable option for this question.
b. Drill press: While a drill press does have a rotating tool, it does not have a linear tool feed motion. Instead, it has a vertical drilling motion.
c. Wood lathe: A wood lathe has a rotating tool, but its tool feed motion is circular, not linear.
d. Scroll saw: A scroll saw has a linear tool feed motion but does not have a rotating tool. It has a reciprocating saw blade instead.
By eliminating the options that don't have both the rotating tool cutting motion and linear tool feed motion, you can conclude that option a, milling machine, is the correct answer.
