CNC Supervisor Interview Questions and Answers

I used water-soluble coolant in the machine.

• Water-soluble coolant is commonly used in CNC machines.

• It is a mixture of water and additives that help in cooling and lubricating the cutting tools.

• Water-soluble coolant is preferred for its ability to dissipate heat and reduce friction during machining operations.

• It also helps in flushing away chips and debris from the cutting area.

• Examples of water-soluble coolants include emulsions, synthetics, and semi-synthetics.

Various measuring instruments are used in machining to ensure accuracy and precision.

• Calipers - used to measure the distance between two opposite sides of an object

• Micrometers - used for precise measurements of small distances

• Height gauges - used to measure the height of a workpiece

• Dial indicators - used to measure small distances or angles

• Gauge blocks - used as a reference for setting up other measuring tools
