What is the basic organization of a STEP-NC control file?
A STEP-NC control program is organized into working steps. Each working step describes an operation that contributes to the manufacture of the part. For example, it might rough out a pocket, spot-drill a hole, or finish mill a surface. An operation is applied to a manufacturing feature and it can be described parametrically or explicitly using a tool path. There are several conformance classes for implementations. For basic implementations, the STEP-NC file always contains toolpaths. In more sophisticated implementations, the control may generate some toolpaths automatically by applying CAM functionality to the GD&T and feature data.
