CNC Setter Interview Questions and Answers

The first step of setting up a CNC machine is to power it on and initialize the system.

• Ensure the machine is properly grounded

• Check the power source and voltage

• Turn on the main power switch

• Initialize the system by following the manufacturer's instructions

Tolerance in CNC machining refers to the allowable deviation from a specified dimension or feature.

• Tolerance is the acceptable range of variation in a dimension or feature of a part.

• It ensures that parts fit together properly and function as intended.

• Tolerance is typically specified in units such as millimeters or inches.

• For example, a hole may have a tolerance of +/- 0.1mm, meaning it can be 0.1mm larger or smaller than the specified size.

• Tolerance can be affected by factors...read more
