Initial design advise wanted

[driftspin]

Ok... so i am in a bit of a struggle... i am not sure about my gantry beam.. i have not found a way to calculate deflection for the beam.. Iam not a strucural engineer ☺

So my beam is 940mm wide between the rail blocks. It is a 120h x80w x4t mm profile.

The maximum z extension is about 25cm on the tip of the tool.
Planned working extension maybe 15cm


The tool is extended about 15 cm.

Can sb point me to a tool to guestimate deflection based on real world cutting forces?

Is read on this forum cutting forces in any given direction do not exceed 400Newton? In soft metals.


I need this info to guestimate the total weight of the gantry and continue on to electronics selection...


Any help is welcome here.

Bert.

for soft metals 120x80 x4 is not rigid enough . Weld 2x / 1 thin side and one wide side 10mm steel plate/ and you will have reaper
