If the shape of the tool is a little bit complex,
I'm afraid you'll have to use finite elements analysis (FEA).

These are rather complex softwares, and I know only one free,
code_aster, but I never used it.

http://www.code-aster.org/

Scilab has a primitive, fec(), to display the results of FEA,
but not to compute it.

And there is an Atoms module for FEA on trusses

But I don't know if there is any 3d FEA module for Scilab.
