Sirs:
In McGraw-Hill’s Machining & Metalworking Handbook I found the following formula for the clamping force by a round eccentric:
P = Q l . l/[tan(?+?1) +tan(?2)]r
Where:
• r: Distance from pivot point to contact point of the eccentric and the machined part surface
• ?: Rotation angle of...
Hi!
For those fond of mechanisms and kinematics this is a great site: http://kmoddl.library.cornell.edu/
Models, tutorials, references, free e-books, etc.

Thanks for your Mike.
I am also considering a independent system for clamping the sheet.
My main interest at this moment is to decide on the best suitable mechanism that tranforms human force (hand or foot) into one that cuts mild steel.
Which would you consider the minimum angle for the...
Thanks to Mike and TVP for your hints. I´ll try to find that literature.
To BillPSU: The intend is to design a manual operated shear press that cuts mild steel sheets up to 18 or 20 gauge.
I´m out of the US and I'm analyzing the feasibility to commercially produce this product.
I like DIACRO...
I´m tryin to design a manual press based on the eccentric mechanism. The problem is that I’ve not been able to find a formula that takes into consideration friction. The problem could be stated as follows:
Given a Torque T, a power shaft with diameter D supported into two journals with diameter...
