Calculate Cutting Force Metal Sheets

1kn 112 tons station size land distance the larger the perimeter of the cut hole the larger the tonnage required.

Calculate cutting force metal sheets.

Ultimate tensile strength psi. 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. Number of draw reduction 9. Die edge radius in.

F p x t x psi. Sheet metal knowledge menu sheet metal manufacturing and services. 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. Area of invert fillet 14.

Punch edge radius in. Has pre entered densities for dozens of commonly used metals and metal alloys like steel aluminum nickel iron copper cadmium gold silver etc. Correction factor for flat blank length 5. Shape a dimension ld land distance.

There is also an axial force but my priority is radial. 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. Draw reduction percentage 10. Metal weight calculator online free steel weight calculator.

Generate optimized cutting patterns based on the available stock sheets by nesting the required parts. Number of drawing process 7. Pre form for full circle forming 6. Area of flat ring 11.

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. You can calculate the punching tonnage been required with the help of the following punching force calculation formula blanking force formula. This equation will calculate the force required to pierce or shear sheetmetal. We normally use a rake angle between 0 5 and 3.

Area of cylinder 12. Online panel cutting optimization software. Area of fillet 13. Flat blank length 4.

1 ton 8 90 kn. 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.
