Flat blank length 4.

Calculate cutting force metal sheets.

F p x t x psi. Area of invert fillet 14. So i m interested in how to calculate the tangential ft and radial fr during cutting aluminum with an 8 mm end mill with 4 flutes. Sheet metal knowledge menu sheet metal manufacturing and services.

We normally use a rake angle between 0 5 and 3. If you punch round holes or square holes or some other forms of holes through a given thickness of metal you just want to know the force required to punch a hole in steel. However in the design of rotary shear the sheet metal cutting force is calculated based on the blade support in the straight motion which inevitably cause inaccurate calculation make the design size deviation and will affect the normal use of performance. Generate optimized cutting patterns based on the available stock sheets by nesting the required parts.

Die edge radius in. Punching force calculation how to calculate punching force in tons punching force 25 x land distance x material thickness x material factor x shear factor note. Area of cylinder 12. Ultimate tensile strength psi.

Area of flat ring 11. Punching force calculation formula. There is also an axial force but my priority is radial. Pre form for full circle forming 6.

F is force required in pounds p is perimeter around area to be sheared inches t is sheet thickness in inches psi is the shear strength rating of the material in pounds per square inch. Online panel cutting optimization software. Number of draw reduction 9. With this calculator you can determine the force required to shear sheet metal simply by entering the material s ultimate tensile strength thickness and blade angle rake angle.

Correction factor for flat blank length 5. Area of fillet 13. Shape a dimension ld land distance. You can calculate the punching tonnage been required with the help of the following punching force calculation formula blanking force formula.

1kn 112 tons station size land distance the larger the perimeter of the cut hole the larger the tonnage required. Punch edge radius in. 1 ton 8 90 kn. Draw reduction percentage 10.

Has pre entered densities for dozens of commonly used metals and metal alloys like steel aluminum nickel iron copper cadmium gold silver etc. Calculate the weight of a steel beam bar tube profiles channels or a simple metal sheet.
