About NC Sequences
An NC sequence is an assembly (or workpiece) feature that represents a single tool path. The tool path consists of the following components:
Automatic Cut motions, that is, tool motions while actually cutting the workpiece material.
Approach, exit, connect moves.
Additional CL commands and post-processor words (for example, feedrates, PPRINT, OPSTOP).
NC sequences are classified into:
Automatic—Creo NC controls the smoothness of the tool path.
Manual—You control the smoothness of the tool path.
