Diversion of drawings to divert trouble
The other day, I was working on a job where I was asked to design a piece of machinery that would modify an existing piece of equipment and duplicate another.
It should be possible to assemble it normally without any problems,From the site when assembly beginsYou've hit the A component. I mean, if you move it, you'll hit it. There were a few places where I was told that
Its location,Parts of the design that have not been changed and have been used without modification. It was.
The cause is simple: "I believed in it.
The reason for diverting the drawings is simple.
And the existing facilities are running smoothly.Because I thought, "If there's nothing to change, maybe I don't need to see it."I know, right?
itCause of failure to detect interferenceIt is. The job was a 2DCAD job, so there was no interference check function, and anyway, I avoided it completely because of the messed up lines.
Be thorough in the process of closing the job (feedback).
Like this time.In many cases, only the title can be changed and the parts to be diverted or the drawings can be diverted.It is.
And since these are the parts drawings of existing equipment that has been completed, I think it is safe to assume that they have received solid feedback from the actual equipment.It means that some machines have no feedback.
The previous machine has probably been handled on site.And I think it is something that the feedback was not completed as it was.
Mechanical design involves a lot of projects, such as designing large machines over a long period of time, or designing machines that turn quickly.In any case, the parts are assembled a short time after the machine is designed, right?
Therefore,Time is allowed between design completion and assembly. Most of the time, the next job is started by that time.Right? In such a mixed situation.If you don't "close" each job, things like this will happen.The first is the
There's probably no trick to it, and I think it's just a matter of making corrections and overwriting them in an unobtrusive way.
The problem with that feedback is that it blurs the lines of responsibility.
Once it is noticed and addressed on site, it is passed on to the designer, who revises the drawings and the person managing the drawings replaces it. Registration. This,No feedback work will be completed if any part of it is skipped.I know, right?
0.03 mm (one-thousandth of a sun)There's no trick to this.I think it is a good idea. It would be nice to be able to provide systematic feedback, but when you work with a wide range of customers like we do, you have to adapt to the structure of each customer, and to begin with, theIf there was no feedback mechanism, it would be a little difficult to improve.It is.
Finally.
A diversion case like this one,The reference drawings should save design man-hours and a reasonable amount of design cost, and there should be fewer problems.Right?
If the work is done well, they say, "We don't want anything to happen," and if it looks good after a long check, they say, "Look, if we use the reference drawings as a basis, it should be fine, right?" If you take the time to check, you will be told, "See, it will be fine if we use the reference drawings as a basis.
On the other hand, if there is interference, as in this case, the delivery date will be delayed because the site will stop, and that will cost more. But that is a loss for both the designer and the site. So, in such a case, we end up saying, "We should have checked with each other....
That's why diversion cases are so difficult.I think that I am.
These diversion projects have a very large hidden risk, so it is very important to present that risk from the estimating stage.
It is important to tell them in advance, "We will use it as is, but if something goes wrong, it may take twice as long as this," so that they understand.Yes.
That's it.
