David laser scanner and reverse engineering

Postby NARMELLA » Tue Nov 18, 2014 4:45 pm

Hi

Revers engineering is a part of my occupation and in this topic i want to put some examples of reverse engineered parts .

This is a reverse engineering by using a scan of a gear ( Created by david laser scanner ) and solid works.
Let's take a look to :

This a scan of a gear ( Take a look for more information )

Now the scan file is loaded and it is ready to use

For this one i want to use Solid types modeling tools instead of Surfacing tools or scanto3d utility .
Lets start

Thanks for this but a couple of questions.
How do you extract datum to use in the parametric models? Are you just taking points for dimensional date or are you actually extracting profiles, and if so how?

Hi,

Some necessary changes on an old special milling cutter for reuse.

And modeling by using solidworks.

And now the model is ready to use it in a cam software .

Hi Johnathan,

It's perfect :D

Hope to see more results in this topic like yours.

Good luck

Is it also possible to use this way of reverse engineering for bigger parts, i have got an upright of 500000faces and the scanto3d fuction is up to 3000?
