research on Friction in Forging Dies, focus on the electrical part of it, like what sensor we can use and why

In this proposal need to research on Friction in Forging Dies, need to focus on the electrical part of it, like what sensor we can use and why. Will the sensor be in use while the billet is being forged, and if machines calculate score not on how hard you hit but instead how fast it travels after it is hit, and if the size of the cylinder can let us to use the nitrogen to generate enough pressure and why if we can and why if we’re not. i added a book too, chapter 5 might help too
