Thanks

You are welcome!!! God bless you too!

It is not fully required but since I include the preload on the screws I prefer to include a separation contact with the corresponding friction value based on the materials of the two bodies, in this case steel-steel.

@@lucmartz It shows no modelling for rods for bolts, right? Otherwise will take too much time, and unstable model, failing to converge.

@@Info-God correct. I use “connectors” which is an idealization using line elements (beam element).

@@lucmartz Gotcha. 😉

Yes! With x-ray view

Yes! With x-ray view

It is not complex... please check this video ruclips.net/video/EplnVq4Dn00/видео.html

​@@lucmartz thanks for the video tutorial.

I certainly have a 3D model :) I can consider to share it. I will post a video soon about the design it self and maybe the link for download

@@lucmartz That would be amazing, i appreciate it if you do :D

@@lucmartz also another question, what was the total or estimated cost?

@@shooterwashere2520 good question. I have no idea at this point but I will cover it on the video.

@@lucmartz Got it, thanks!

@chuckd7177 how large is the part? The idea of run the simulation with shell elements will depend on the thickness, if you can control the setting of the wall thickness on the slicer, I think you can use for simulation a thickness parameter for the 80% of the actual wall thickness. Remember that layer orientation is key.

@@lucmartzMost, almost all, of my work with FEA was with metals. I sort of thought about layer orientation after I wrote my first comment. I'm still thinking about it. I'm new to 3d printing (filament printer) and still learning. There are lots of options in the slicer. I "think" (meaning I have no proof) with infill (lots of options for the type of infill) the part would be stronger (less deformation) than would be predicted by just using the wall thickness as the shell thickness. Maybe I need to figure out how to do a 3 point bending test. :) I could quit guessing then.

@@chuckd7177 first step, get the 3 point bending test then :) don't forget to use non-linear analysis, linear won't work with plastics.

I made to beams one was hollow and the other was solid. I hung weights from the center of each beam and measured the deflection. From the measure deflection of the hollow beam and using the equation for deflection of beam for a three point bending test I calculated the modulus of elasticity for the PLA plastic. The modulus matched fairly well with the value I found on matweb. Using the modulus I calculated from the hollow beam, I calculated the deflection for the solid beam and compared it with the measured value for the solid beam. The measured deflection was about 35% greater than the calculated value. Based on this very limited testing it would better to use shell elements for modeling of printed parts.

@@chuckd7177 sounds like you have been having some fun. What are the dims of the beams? What load you used? I would like to try on the software

Wait for it!! It is going to be ready soon.

It can but not with nice surface finish

Yes! 6061

Do you mean to use it as brazing element?

skhumbuzo cele great question and the answer is yes! The results are very similar but frame analysis is quicker and at the end if you have aprópiate safety factors it work perfectly

@@lucmartz..... Thank you very much for the on point quick response. I like your teaching style. Cheers

Adam Adam in my experience machining aluminum, it is not going survive much time. I will give a try with brass and upload a new video.

How about the method shown in 4:35 ? You can add a perpendicular or angled line, by selecting a plate material that adjust to the dimensions can be used useful for the BOM.

That’s a nice question. I will let you know once I have tutorial ready.

thesilverjewel I’m not sure if jewelry quality. For sure I can say it works for engrave metal keychains if are made out of aluminum

Daniel fer. L con mucho gusto!!

Hola, por si aun lo quieres, yo usé este link para descargar el libro en donde vienen las medidas, está en la pagina *488 del pdf* www.academia.edu/20390049/DIBUJO_Y_COMUNICACIÓN_GRÁFICA

@@JuanMHdez muchas gracias a sido de gran ayuda

Hola Esteban, perdón por no haber respondido antes, grabcad.com/library/angle-vise-2

I don’t have with me the part anymore, I will be sharing soon another engraving. In any case, it was not beautiful but it is acceptable for my objective.

Johnaton Ince I did the part on a lathe and then created these other features that you see in this video. But! This machine is not suitable for cut aluminum. I don’t recommend this machine for that. I spent the money and I don’t complain, at the end it was for experimentation.

@@lucmartz what other china cnc could I use for aluminum? 😇

Johnaton Ince you can look for a ER11 collet on Amazon.

@@lucmartz Is this the collet you bought on Amazon? <I removed the Amazon URL for the silly RUclips compliance.. so here's the rest of the URL/product ID> /dp/B07D75BPB3/

Unfortunately not. Best Regards.

esmio....

Yadollah Zarif for the Hidropower gate videos I don't have audio, it is more about the workflow than a tutorial. Thanks for asking, I will upload tutorial with audio soon

The maintenance service changed the hard drive... that's all I can say
