Quarter Manufacturing Force Estimate

AI Thread Summary
To estimate the force needed to stamp an American quarter, key factors include yield strength and coefficient of friction of the materials involved. A significant press capacity can simplify the process, as it can handle the required force without needing to account for these variables. The discussion highlights the importance of understanding material properties in the stamping process. A link to a relevant coin stamping press is provided as a resource. Overall, having the right equipment is crucial for effective coin production.

Hi,

What would be the approach to getting a good estimate of the amount of force needed to stamp an American quarter? (This is assuming you have the blank already made)

I'd like to get a good estimate, but more importantly an idea of what numbers go into this estimate, i.e yield strength, coefficient of friction, etc.

Thanks!

With a big enough press, you don't have to worry about yield strength, friction, etc.

Posted June 2024 - 15 years after starting this class. I have learned a whole lot. To get to the short course on making your stock car, late model, hobby stock E-mod handle, look at the index below. Read all posts on Roll Center, Jacking effect and Why does car drive straight to the wall when I gas it? Also read You really have two race cars. This will cover 90% of problems you have. Simply put, the car pushes going in and is loose coming out. You do not have enuff downforce on the right...

Thread 'Physics of Stretch: What pressure does a band apply on a cylinder?'

Scenario 1 (figure 1) A continuous loop of elastic material is stretched around two metal bars. The top bar is attached to a load cell that reads force. The lower bar can be moved downwards to stretch the elastic material. The lower bar is moved downwards until the two bars are 1190mm apart, stretching the elastic material. The bars are 5mm thick, so the total internal loop length is 1200mm (1190mm + 5mm + 5mm). At this level of stretch, the load cell reads 45N tensile force. Key numbers...

Thread 'Cantilever help'

I'm trying to decide what size and type of galvanized steel I need for 2 cantilever extensions. The cantilever is 5 ft. The space between the two cantilever arms is a 17 ft Gap the center 7 ft of the 17 ft Gap we'll need to Bear approximately 17,000 lb spread evenly from the front of the cantilever to the back of the cantilever over 5 ft. I will put support beams across these cantilever arms to support the load evenly
