Reverse engineering

Anonymous — Tue, 26 Sep 2017 03:06:27 GMT

Hello,

I have to reverse engineer part for my department.

I measure everything using my digital vernier caliper.

The results are far from similar.

Infact, there are some errors as I could not get the key pad skeleton to fit in the box.

The keyhole is also having access.

How can I go about reverse engineering?

Better measuring or try Autodesk's Recap. Digital camera with a fixed focal length lens and snap pictures from all angles with 50% overlap.

I have choosen measuring but the whole piece is hard to measure.

I was thinking of measuring the parts inside that is going to be fitted in and design the housing using minimal features

It looks like an easy piece to model..

Not sure what we can do for you except tell you to practice more.

Seems like you just need more experience..

There are really no "tricks" to reverse engineering..

Its just experience/skill that gets the job done..

If that's a part your company makes don't they have a drawing or model already?

My company buys it from a manufacturer.
They do not have any drawings only the physical part.

Looks easy enough to model.

Measure it with your vernier,

I used to do this all the time with samples, because

there was either no drawing done, or no drawing available.

If you know the important dimensions and where it fits into,

the measuring from scratch will give you just as accurate a model

as a scanned one, if not better!!

You could get it 3d scanned as well, but that would only

really be useful for more complicated, curvy objects that are

difficult to draw accurately.

3d scanning is very expensive, so an object which is simple

to measure and draw, would be better measured

Take photos from Top, Front, Side and place and scale in sketches (using a couple of easy to measure features).

Model the part as best you can.

Attach your attempt here.

I have attempted to draw the part but it is nowhere near the actual.

I cannot do the sweep and I have not tried fitting them together.

Hello,

i'm new in this plattform. If you are still in need just drop me a line and we could check what's possibile.
