Question

Automated mills, lathes, and water jet cutters are devices commonly used in this technique. For 10 points each:

[10h] Name this type of CAD-aided machining commonly known by a three-letter initialism. Haas Automation mostly makes tools for use in this technique.

ANSWER: CNC [or Computer Numerical Control]

[10e] In water jet cutters, the water jet is often mixed with an abrasive material such as this one. This material names a type of paper with an abrasive glued to it, whose strength is measured in grit.

ANSWER: sand [accept sandpaper]

[10m] An alternative to water jet cutters cuts through electrically conductive materials using one of these substances. In arc welding, an electric current causes air to experience breakdown, becoming one of these substances.

ANSWER: plasmas [accept plasma cutter]
