Power and thermal energy of cutting or machining (metal, wood ...)

Christophe · by **Christophe** » 17/10/19, 16:50

We all know when we cut or we factory ... it heats well but uh ... how much?

Today I would like to quantify this energy!

What is the method of calculation to estimate this energy "tearing of matter"?

I think we can find a simple formula, with the following parameters: G grams of M machined material = J joules? For the power it will suffice to introduce the parameter T time ...

I ask myself the question because I cut or pierce at the moment small pieces of aluminum and just by drilling holes 5mm I can not hold the hand to bare a few inches ...

Bah a upper bound it's the engine power of your tool, right? As a rule not much (1 to 2kW?)

Yes that I am doubted a little... but a more precise calculation would have suited me! : Cheesy:

Besides, I think my grinder consumes the same vacuum that load ... So very difficult to estimate the useful power!

Sorry, I do not know how to do it. But out of curiosity, what would you do with a more precise calculation?

Ben the one I proposed above ...

That in terms of energy it must depend on the number of grams of material, the machined material and certainly the fineness of the tearing off ... my concern is to put figures on it ...

If we want an estimate of the temperature we must also take into account the shape of the room, the ambient temperature and its thermal properties (conductivity in particular)

My question, I repeat, is "out of curiosity, what would you do with a more precise calculation?" If it's "just for the sake of knowing", that's an answer!

That's it! It's for my education!

I think it's different depending on the materials we're working on.

it would be very surprising and personally I doubt it very much
