As reported by The Fabricator in their article, “Cams, cams, and more cams,” cams play a critical role in converting vertical motion into horizontal force in industrial applications, especially when precise alignment is required.

Cams are essential components in die systems, transferring motion while withstanding friction and high force over millions of cycles. To enhance cam performance and longevity, certain guidelines must be followed. First, it’s important to use dissimilar metals for die sections that interface to avoid friction-induced heat, which can cause cold welding or galling. For instance, aluminum bronze is a great choice for cam slide drivers and wear plates. Second, when designing the cam slide, it’s vital to bypass the entire wear surface to prevent wear plate grooves, which can lead to “cam jump” and damage cutting punches.
For optimal precision, cam slides should extend as close to the cutting point as possible, minimizing movement at the punch point. Using a tapered matrix for cam piercing is another key practice, as it prevents slugs from tipping or jamming, ensuring smooth operation. A slug shedder made from hardened tool steel is recommended to force slugs downward in the die, further promoting efficient operation.
By adhering to these cam design principles, manufacturers can significantly improve both the performance and lifespan of their cams.
