Which action should you take?

Choose only one option

It changes the tool in the spindle

It stops the spindle rotation

It activates the coolant system

It turns the spindle on in a clockwise direction

Question 3: What is the role of the CNC machine's offset parameters during calibration?

Which action should you take?

Choose only one option

They adjust the machine's electrical supply

They compensate for tool wear and mechanical inaccuracies

They control the machine's overall speed

They reduce the thermal expansion effects

Question 4: What is the function of the coolant in CNC machining?

Which action should you take?

Choose only one option

To speed up the material handling process
