CNC Machining Technology Flashcards

This flashcard set covers CNC machining technology, the use of computer numerical control to drive machine tools that cut metal, plastic, and other materials into precise parts. It moves from core ideas about subtractive manufacturing and cutting motions, through machine types and axes, then coordinate systems and G-code programming, tooling and workholding, and finally setup, quality checks, and applied production practice. Each group builds on the one before it, so the early cards provide vocabulary and principles that the later cards put to use.

To study effectively, read each question and answer out loud, then explain the idea in your own words before checking the answer. Pay close attention to units, since inch and metric values cause many errors, and to the exact meaning of codes such as G90 and G91, which can vary between controls. When you miss a card, return to it later rather than memorizing the wording alone. Use a simulator or a supervised dry run whenever you can to connect the vocabulary to real motion, and treat safety rules as non-negotiable throughout your practice.
