A program contains the line: T0202. What does the second "02" represent?
Tool number
Tool offset number
Spindle speed
Feed rate
Why should you never wear gloves while operating a CNC lathe?
Gloves can get caught in rotating parts
Gloves protect your hands from coolant
Gloves keep your hands warm
Gloves improve grip on controls
If the machine displays an overtravel alarm, what is the most appropriate first action?

Try to move the axes further
Ignore the alarm
Turn off the coolant
A student is asked to optimize a turning operation for both speed and safety. What should they consider when selecting spindle speed and feed rate?
Only the material type
Tool material, workpiece material, machine limits, and safety protocols
The color of the chips
The size of the control panel

Flying chips and debris
Increased spindle speed
Tool breakage
Coolant overflow
A student is setting up a part and needs to ensure the X-axis zero is set correctly. What should they do?
Touch off the tool on the part’s diameter and set the X-axis work offset
Set the Z-axis only
Ignore the X-axis
Use the previous part’s offset
Why is it important to keep the lathe’s guarding in place during operation?
To prevent chips and coolant from escaping and protect the operator
To increase spindle speed
To improve tool life
To reduce noise
A program is producing a tapered part, but the taper is incorrect. What should the operator check first?
Tool offset values and program code for correct X and Z movements
Coolant level
Spindle speed
Machine color
You are asked to improve the surface finish of a turned part. What changes might you make to the program or setup?
Reduce feed rate, increase spindle speed, and use a sharper tool
Increase feed rate and use a dull tool
Turn off coolant
Use a larger tool nose radius only
A student is troubleshooting a program that stops unexpectedly after a tool change. What should they check to resolve the issue?
Ensure the correct tool offset is called and the tool is properly loaded
Increase spindle speed
Turn off the coolant
Ignore the problem
