What does the G01 command do in CNC programming?
G01 tells the machine to move in a straight line at a controlled cutting feed rate.

How do you specify the speed of the cutting feed when using G01?
You specify the feed rate using the F word, for example, F100 means 100 units per minute.

What is the difference between G00 and G01 commands?
G00 moves the tool quickly without cutting (rapid move), while G01 moves the tool slowly with cutting feed.

Write a simple G-code line to move the tool linearly to X50 Y25 at a feed rate of 150.
G01 X50 Y25 F150

Why is it important to use G01 for cutting instead of G00?
Using G01 controls the speed to avoid tool damage and ensures a smooth cut, while G00 is too fast and can cause damage.

What does the F word specify in a G01 command?
✗ Incorrect
The F word sets the feed rate, which is the speed at which the tool moves during cutting.
Which command moves the tool rapidly without cutting?
✗ Incorrect
G00 is used for rapid positioning moves without cutting.
What type of movement does G01 command perform?
✗ Incorrect
G01 moves the tool in a straight line at a controlled feed rate for cutting.
How would you write a G01 command to move to X100 Y50 at feed rate 200?
✗ Incorrect
G01 X100 Y50 F200 moves linearly to X100 Y50 at feed rate 200.
Why should you avoid using G00 for cutting moves?
✗ Incorrect
G00 moves the tool rapidly without feed control, risking tool damage during cutting.
Explain how G01 linear interpolation works and why the feed rate is important.
Think about how the tool moves and why speed matters during cutting.
