00:00 Introduction. We'll go over which design aspects of CNC machining are explained in this video.

0:42 Design restrictions. It's important to know the design restrictions of CNC machine before designing parts. Therefore we'll cover tool geometry, tool access, workpiece stiffness, tool stiffness and work holding.

3:13 Cavity depths. Moving on to design rules, starting with cavity depth. You'll learn how to design cavity depths with important design rules in mind.

3:40 Internal edges. Learn how to design internal edges with CNC design rules in mind.

4:30 Thin walls. Learn how to design thin walls with CNC design rules in mind.

5:07 Holes. Learn how to design holes with CNC design rules in mind.

6:05 Threads. Learn how to design threads with CNC design rules in mind.

6:42 Tall features. Learn how to design tall features with CNC design rules in mind.

7:01 Small features. Learn how to design small features with CNC design rules in mind.

7:27 Tolerances. Learn how tolerances should be defined.

7:47 Maximum part size. Learn about the recommended part sizes when designing for CNC machining.

8:20 Undercuts. We'll discuss when to use undercuts and how to design them.

9:11 Undercut clearance. Finally, you'll learn how to properly add undercut clearance to your design.
