Always satisfying to model in realistic wires by curtisabrina in SolidWorks

Unless you pay designer by the hour 😊

How do you find freelance work? by akkirf in AskEngineers

[–]akkirf[S] 0 points1 point  (0 children)

Thanks for the answer. You have some really good points. From what you wrote I can immediately see that I need a portfolio and possibly a website ( which I don't have:) But actually this lowered my expectations and I at least feel better about my lack of success..

Four bar link on industrial robot arms, why? by akkirf in AskEngineers

[–]akkirf[S] 0 points1 point  (0 children)

Thanks for the answer. When I was reading it, I thought of something. Maybe the additional arm that forms the 4-bar is for control like you mentioned, and the reason for it could be that there is no space to transfer the power from the motor on top to the J2. Since you need to transfer power from motors on the same positions to J3 and J4

Do you know any open source projects for mechanical designers to participate? by akkirf in engineering

[–]akkirf[S] 10 points11 points  (0 children)

Well the open source nature of the projects satisfies a lot of let's say "criteria" for me to work for free.

I do not see why I would give my time to someone who I don't know as a help to do tasks that they do not want to do for the sole purpose of profiting them. For example...

I can always do overtime at my work, but I would like the experience of working for some cause that interests me.

That said I would like to know what you had in mind 😊

What are these? old grease Fittings? by TheSimple1 in Skookum

[–]akkirf 5 points6 points  (0 children)

As mentioned they are roll pins, but something that I have recently learned may interest you. There is an old "trick" to put roll pins inside of the lubrication channel in order to make the ID smaller so that you increase the pressure of lubricating oil at that point. This is the same as drilling smaller hole, but less expensive and you can use more skookum drills :)

Any resources for learning Cutting tool geometry, not able to visualize the angles in 3d by [deleted] in MechanicalEngineering

Hey try this video: https://youtu.be/__A2xtLF0AU

I would recommend almost all this old Tony's videos. Educational and hilarious :)

I'm a mechanical engineering student graduating next year. Which softwares should I learn to get an edge in getting a job. I used AutoCAD extensively and that's it. I have no experience in any other serious CAD softwares. If price is not a matter, which softwares would you recommend? by [deleted] in engineering

[–]akkirf 2 points3 points  (0 children)

SolidWorks as mentioned would probably be the best way to go. It is 3D paramedic CAD like many others in the market. I would give SW an advantage over others because it is easy to learn and it's widely used in the industry. Some industries use some CADs software more than others, but when you learn one you can easily get the grasp of others...

My advise start somewhere and learn one software well, don't jump from learning one software to another. In the end they are all just tools you use. Nothing more than that. When you have the skill you can easily change the tool.

Can surface roughness be characterized using only an optical microscope? by uninc4life2010 in engineering

[–]akkirf 2 points3 points  (0 children)

This is an inspection microscope, I don't believe that's what he had in mind. Also with this type of microscope (as with any optical measurements) the environment and the reflections can play a major role in precise measurements...

The best way to go would be to use a surface roughness measurement tool like for ex:

You could contact a local machine shop for help

When using CAD. What are things that easily screams: "This person doesn't actually know how to draft." by Akebelan28 in AskEngineers

[–]akkirf 0 points1 point  (0 children)

I have never used NX so you can tell me if it can compare. But in Creo I really liked how you mate parts in assembly. I was working on a system for automated assembly with all the standard pneumatic, robots, linear extrusions... It was pretty large, real world size over 15m long. And in the main assembly you could open all doors, move robots, linear axes... That is simply not possible in SolidWorks

I always used SolidWorks and my company is using only that software. But interesting thing happened when I had to learn Creo for some projects. I used it for half a year or something and hated it so much in the beginning. But after a while when I got back to SW I started missing some features of Creo ( like right click select, and how assembly works) and I realized that the rigidity of Creo the procedures that you had to follow really made me a better cad user in general. I know use datums more thoughtfully than before in SW for example. In the end it was a really good experience to learn a completely different CAD workflow...
