Objectives
Identify the characteristics of the CNC programming language and programming functions, creating programs for CNC milling or turning.
Prepare and operate CNC machine tools, executing pre-established programs.
Identify the main features of a CAD/CAM system (computer-aided design and manufacturing), including its configuration and capabilities.
Model and prepare geometries and other information for subsequent machining on CNC machine tools (lathe and milling machine).
Machine models using CNC machine tools, employing both manual programming and programs previously generated with the aid of CAM applications.
