marcellosavoldi commented 3 years ago

can you describe better what did you create? could be interesting an immage and/or a screenshot of the family table for example... thanks

Mick3Lozzo commented 3 years ago

These are low head plastic screws from Misumi, with a pseudo-Torx screwdriver footprint.

marcellosavoldi commented 3 years ago

thanks @Mick3Lozzo , I assuming all row signed are good... only a doubt.... off topic .... Do we need to buy some tool to use this screws?

other curiosity.... why you didnt use a common cross recessed as following? for exemple: SPE-M5_P or PACK-PPSA

the head of these I proposed you, is thinner than your...

Mick3Lozzo commented 3 years ago

the head of these I proposed you, is thinner than your...

Nope. 

Mine is 1.5 mm.

only a doubt.... off topic .... Do we need to buy some tool to use this screws?

If we want, this one. I think is similar to a Torx one @marcellosavoldi. Maybe we already have it in the workshop?

@Mick3Lozzo how did you set the material properties?

Mick3Lozzo commented 3 years ago

@Mick3Lozzo how did you set the material properties?

For now, I've set PP, (Polypropylene). The correct material should be PPS (Polyphenilene Sulfide).

Here I found a comparison between the two materials.

The density is really similar, if we think is better, we could think to prepare a proper *.mtl file.

Today I have tried them, and the mounting tool we have in the workshop fits well the slot.

@Mick3Lozzo please do not invent yet another method to set the material for commercial parts. We have a standard way documented in the guidelines, can you stick to it? 🙂

Mick3Lozzo commented 3 years ago

@fiorisi yep, but this is a screw belonging to a family table, If we set the correct *.mtl file, it will work for all instances.

Mick3Lozzo commented 3 years ago

Created and assigned pps material file, density set to 1.7^10-6 kg/mm3, the weight of a single screw results to be 0,41 g.

And it is PERFECT.

@Mick3Lozzo I would not create a new material. Creating a material is not only about the density, there are many other parameters that must be set correctly and must be added only through a pull request (you can not commit the file directly).

Please follow the standard procedure for commercial components. If you want to change the procedure please add a point to the next @icub-tech-iit/silo-mech meeting. Until then, please always follow the guidelines. 🙂

Mick3Lozzo commented 3 years ago

@fiorisi done. And added a point to the next silo meeting.

Great. I let the maintainer @marcellosavoldi review and close the issue.

marcellosavoldi commented 3 years ago

I am not able to understand that it was saved with the right license, so i trust it. otherwise ok. @Mick3Lozzo , you can close.
