Force required for cutting sheet metal | Physics Forums
2018-5-17 · The moving blade should not spring away from the fixed blade more than 10% of the sheet thickness, or 0.15 mm = 0.006" under a 2000 lb cutting force. The above numbers seem realistic based on my experience attempting to cut 16 gauge sheet metal with a pair of tin snips.

Sheet Metal Bending: Basics, Allowance, and Tips
2021-3-28 · Sheet metal bending is an operation that involves using forces to change the shape of a sheet. This is done to achieve the desired form or shape needed for a manufacturing process. The external force used alters only the external features of the sheet. However, parameters of the one type of sheet metal such as length and thickness remain the ...

2015-11-30 · Flattening force = Area x Compressive strength = 6.745 x 38,400 = 259,008 lbs. Flattening force in tons = 259,008/2,000 = 129.504 tons. Never use a press that is rated for the exact amount of required tonnage you have calculated. Always add a minimum of 20 percent for safety. In this case, the minimum press tonnage should be 155 to 175.

Sheet Metal Bending - Manufacturing Process
2017-9-10 · Flanging is a process that bends an edge, usually to a 90 degree angle. Figure:273. Sometimes the sheet metal's material is purposely subjected to tensions or compressions, in the processes of stretch flanging and shrink flanging respectively. In addition to bending the edge, these operations also give it a curve.
