Introduction to CAD and CAM for Machining

Provided by: ToolingU

"Introduction to CAD and CAM for Machining" provides a foundational overview of CAD and CAM systems and how they are used in CNC machining operations. While CAD greatly streamlines the process of part design, CAM ensures successful production by converting the part design into precise machine movements. This class describes CAD design methods, including the different types of part drawings and modeling, and the CAM data conversion process, including how toolpaths and movements are plotted based on design data. Without CAD and CAM, most modern CNC machining would not be possible. They are the first step in CNC part creation, and their correct execution is necessary for a successful part creation process. Understanding how CAD and CAM are used in the CNC process is an essential building block to understanding how successful cutting operations are carried out on CNC machines.
