start making the designer

[stephan-design]

Hello, everyone.
After 18 years of working in computer science as a system engineer I am thinking of changing work to make the designer cad or cae . I am a management engineer and electronic expert . I know the norms of technical design, electronic and dare say also mechanical .
I am 43 years old.
Now I ask who might advise me how to start finding work .I don't know how to use any drawing program anyway in computer I did everything from self-taught and so I already started studying on my own on autocad 2018 .

Thanks for the attention, I hope someone contacts me to talk about it.

Hi.

Hi.

have you reasoned that facing a new beginner job you will be paid as a beginner? Usually, at your age, economic needs are much higher than a 20-year-old.

in addition to the fact of the right hunter observation I would point out that knowing the technical norms and reading a design does not mean automatically knowing how to draw. because it is also necessary to know how to contextualize the design in its environment. . so to say, I know how to draw a mechanical carpentry from the rough to the finished, but if you ask me to draw a wardrobe of furniture or a goat in reinforced concrete are lost because the environment is different and the information needs are different and I do not know them while subjecting to the same technical regulations of drawing.
Also not knowing how to use a cad, which is now indispensable, is a point to your disadvantage.
Yours is a jump in the dark that you have to consider with great attention

I quote the colleagues mentioned above, in your case it is not a question of switching from one cad to another if very different (maybe being self-taught may be of help, because there is the basis of another cad behind), but it is a question of changing deeply craft, where your resume can not give you a plus about it.

I have been transferred to the coast for reasons of work mentioned above:
the motivation and that I am looking for a way out of this computer world that remains a world made of available hours exaggerated to carry out works only in certain hours of the day, studying to stay more than updated adaptable to the labor market because very voluptuous .in practice and very lovable and to my age' and seen the trend theological does not give me well thought for the future.
so I was trying to do it as an alternative: the designer .where keeping my current work in my spare time I would start another parallel career, proposing myself free of charge and working remotely. Looking for someone who offers me opportunities, giving me drawings to do without being paid . So this and the idea now I was trying to formalize it by consiring that I am like a crossroads: electronic or mechanical design.
I do not think that life will last anyone in the computer science, because we are considered service staff almost all outsourced at the mercy of maintenance contracts that renew year by year ....

Let us do this: give me a plan to do as if it were a job assigned in the office .cosi you will help me contextualize in the working reality .thanks for the listen, I hope that they follow advice from other people .

steph, my predecessors are right to sell. I mean, for example, what he wrote massive.
However, in order to make you understand what difficulties can be and how little it matters to know the rules of design regarding the context, I pass this little exercise, as I would pass it my client. There's no need for starting chart.

we have to make a concrete well, internal dimensions 120x120cm, thickness of the walls 20cm, thickness of the bottom 30cm, external height 3.5m, without head insole.
We arm the bottom and walls with 1 ø14/20 bar in both directions, both internal and external. border armor will be 1ø8/20.
do you produce the drawings (geometries and armor)?

and, uh, take care that this is an earth-earth exercise. an unexperienced structural designer eats it in 20-25 minutes.

I don't know what you do in computer science, but for example, thecloud architect is a very sought after job. The world is full of designers, already out of itis is able to draw practically everything, I don't think it's a great idea to devote you to a branch where competition is so much, well prepared and younger.

If you want a physical design on which to test your skills I attach a small assembly made for another user.

not enough to pull lines but you need to know work and know how to do at least a minimum of design and calculations.

we can give you another exercise more than mechanics:

realize mechanical reducer with parallel axes with reduction ratio 40 and with solid trees with tab. input power 57kw to 2100rpm.

make mould for cutting boards of sheet metal in s355jr thickness 5 mm inner diameter 20 mm and external diameter 60mm.

design mill for finished product aluminum 3000x10mm.
....

This is what the world of work demands

make the designer cad or cae.I am engineer

Hi.

leaves too much responsibility with little money
and many worries especially when you put "the head on the pillow" :3559:

But it is the most beautiful trade in the world:4406:
Thank you very much

How long should such projects be completed?

 

[meccanicamg]

the reducer in less than 8 hours x 5 days. mold in 8 hours x 3 days. the mill leaves it to be.... that it takes 3000 hours and more people

I have done 2 carlona accounts with the formulas I remember, it is possible that for a steel fo 600, a basic/module ratio of 10, angle press=20 and a service factor of 1.4 a (no overload and work 24/24) the module is approximately 11 ?

already using fe600 says it very long, its designation on ultra ancient, both because there are no gears for gears that turn especially fast in structural steels but at least in hardened and rectified c45 rather than in bonded bonification steels or cementing steels. other thing if you have to report 40 you will have more stadiums and will not have module 11 at all. to straight teeth you don't do it a reducer because it whistles fear...so I would say we don't get rid of it

a service factor 1.4 second agma is for an average heavy application. If you don't work 24/24 means you're not in service s1, but if you have an intermittent 60% what would happen? and the thermal dissipation of the carcass? a module 11 is not among the preferred modules. But you were going to do it with two gears? even if it was possible (over 8-9 ratio you can't manage) you would have big meters wheels and would be uneconomical as well as antitechnological.

I had honestly considered three pairs of gears, the service factor I have taken into account was taken by the zanichelli (apparently useless) , fretfully I imposed z1 as 80 and not taking into account that the teeth in grip are not only two (?). I gave the empirical result... the tables of the unified modules are clear for which the m "correct" to be applied would be 12!

I have struggled (I have not managed completely) to find the tables of the safety coefficients used!

However if I asked the question it was because I was sure that 11 was too big.. .

the only real shortage I suppose was in the choice of material.

in any case this little failure motivates me even more... because if it is morning in 10 minutes I made a "cagate" 13 years ago in 8 hours you would have had ready reducer (with a wrong material but ready)


with regard to dissipaz. thermal (the only thing to say : to improve the profile and surface of the tooth to reduce friction, to "appuntire" as much as possible the edges of the carter, and to create "labels" where possible. . Honestly to have the maximum encumbrance as given, it would serve not little!!

 

[NicoPortorico]

What do you mean by 60% intermittentness?


that the reducer does not work 24/24 ? but does the night stay for example?

 

[meccanicamg]

a reducer with a wrong material breaks. gears dimensional and above all occur with iso 6336 evaluating tooth bending and pressure contact. then microgrid and lubrication. for a non-commercial reducer you can do quietly with profile shift, two only stages because reduction reports up to 7 you do and have no problems. the speech of the intermittent service, is considered at the international level of the families s3...s6.... where there are cycles of operation where the time of march is defined regarding the total time. normally for gearboxes it refers to an hour or otherwise it should be specified.

 

[NicoPortorico]

I do not think it is necessary to make a statement on this subject.

Thanks mechanicalmg.
