Historically, cam design was a trial-and-error process involving hand-drawn layouts and graphical methods. Norton’s second edition pulls the discipline firmly into the 21st century. It emphasizes , focusing on the mathematical functions (like SCCA and B-splines) that govern smooth motion rather than just "connecting the dots." 2. The Focus on Dynamics

Design is only half the battle. This edition bridges the gap between the CAD screen and the CNC machine.

It provides methods for measuring cam profiles to ensure the physical part matches the theoretical design. 4. Why the 2nd Edition Matters

that apply theoretical formulas to real-world industrial problems. The Verdict

The core strength of this handbook is its focus on . A cam that looks good on paper can fail in the real world if it triggers resonance in the follower system.

It discusses how machining errors (scallops and surface finishes) translate into unwanted vibrations in high-speed applications.

If you are designing high-speed packaging equipment, automotive valvetrains, or precision medical devices, this handbook is indispensable. It doesn't just show you how to draw a cam; it explains the physics of why certain shapes fail and how to engineer systems that run quietly and last for millions of cycles.
