Subject: CT and laser scanning of moulds -Reverse Engineering

Hello RP's

For a Project I need to do reverse engineering on vulcanisation moulds.
'm interested in service bureaus, research institutes and companies that
scanning services or machines with Laser, CT or MR.

Does anybody have some adresses of such facilities providing this machines
or service in Germany (or in Europe)?
Does anybody already have experiences with building correct CAD models with
the scanned data (programms, data formate - IGES,STL) ?
I will post a summary of the replies to the list

Many thanks


Dear Sir,

There are a number of service bureaus throughout Europe that Utilize the
DIGIBOT II 3-D laser digitizing technology, and CAD modeling to reverse
engineer existing models. In Germany, contact Invenio Engineering Services,
Tel: 06142/899-248. If you would like the info on all centers in Europe
that provide digitizing with systems from DIGIBOTICS, INC., and CAD modeling
services, please me know.

++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ joerg, please forward your request for reverse engineering to my attention. we have been digitizing consumer products since 1986. until 1996 all of our projects were for dnc/cnc (direct numerical control). we now use imageware surfacer to produce igs surfaced models from our collected data. next week i will be presenting/speaking on reverse engineering. i will present several case examples we completed over the years. society of manufacturing engineers (sme) is sponsoring a seminar in troy, michigan specifically on this topic. we use a cmm contact probe. our cmm has a work envelop of 24" x 24" x 15". regards, jim williams paramount industries, inc. 2475 big oak road langhorne, pa 19047 usa 1.215.757.9611 1.215.757.9784 fax ++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Imageware Deutschland GmbH Gerd Schwaderer Gottlieb-Daimler-Str. 17 50226 Frechen Tel.

call us at Imageware Germany, we know more or less all Scanning service providers, as almost all of them use our software in germany. I also have a contact for service CT's. And talking about correct Cad files from point data... thats what our company lives for, but there more to say than one sentence......

I yust want to mention Imageware of course Intecu with its own laser, Gera

das wären die wichtigsten die mir auf Anhieb einfallen ++++++++++++++++++++++++++++++++++++++++++++++++++++++++
