Here are some common Hobby CNC Terms!

CAD (Computer-aided design)
Geometry authoring tool that involves software and sometimes special-purpose hardware. Current packages range from 2D vector based drafting systems to 3D solid and surface modellers.

CAM (Computer-aided manufacturing)
Considered as an NC programming tool wherein 3D models of components generated in CAD software are used to generate CNC code to drive numerical controlled machine tools such as Carvewright

CNC (computer numerical control)
Refers specifically to a computer "controller" that reads G-code instructions and drives the machine tool.

CAD/CAM part programming
The computer calculation and creation of a toolpath based on part geometry information created in CAD.

Canned cycle
A predetermined machining sequence used to simplify programming. Data Information processed as the basis for calculations. Database Computer storage that holds data and is searchable Mastercam

Detail Drawing
A drawing of a part giving a complete and exact description of its form, dimensions, and construction
