Incline shear blade formula to calculate cutting force

  1. Jun 20, 2012 #1
    Hi ,
    I want to calculate force required to cut a 1200 mm -3.5 mm sheet using incline shear blade.
    Anyone know what formula we can use in this case when we are cutting metal on an blade angle of 1°.

    Please help.

    One could calculate the energy required to shear that surface area (thickness * width), then apply a constant force over the distance. I presume 3.5 mm is the thickness?

    Hi Astronuc,
    you are right 3.5 mm is the thickness and 1200 mm is the width.
