My name is Axel Dannoritzer, 40 years ago, the Dannoritzer Medizintechnik GmbH (medical
and repair technologies) was established as a fine mechanical company. Over the years,
we started to specialize in repair parts and custom-made products for the medical engineering
industry including instruments and equipment. In addition we also produce our own instruments,
especially for the endoscopy sector. Lately, we find ourselves facing a big challenge:
The cleaning of the instruments is getting much more difficult and the requirements are
getting harder to fulfill, we are now questioning ourselves and wondering how we previously
made the grade. I would like to demonstrate it on an instrument. This is an arthroscopy
punch. You can imagine how it got used in surgery and afterwards it is necessary to
clean it. You really must clean it very thoroughly and ensure that there are no infections or
germs left on the instruments. In terms of our production line, this means, that we either
build a disposable instrument, which unfortunately creates lots of waste and costs, or we think
about a solution to construct an instrument which is easily cleansable. On a recent case,
thanks to the software techniques of INNEO, we are able to join different assemblies together.
Here we have a shaft, an agile jaw part and a handle. We create it in a way, that we can
easily deconstruct it in different parts. As you can imagine it is now much easier to
clean the different parts instead of cleaning the instrument as a whole.
Therefore you need the right software to solve this problem positively. With INNEO, we found
the right partner to solve this problem! My Name is Julian Dannoritzer; I am responsible
for the product engineering at Dannoritzer Medizintechnik. A few years ago, we implemented
Creo 2.0 and not only did we change the area of CAD, the constructive side, but also the
uniformity to CAM straight away. The Creo complete Machining Extension module also covers
the area of five-axis. It was really important to us, that we can
lead the whole process from here. On top of that, we also use KeyShot to create rendering
pictures for our online shop or catalogues. My Name is Gerlinde Klaiber, I am an engineer
and my job is to fix this catch on this handle, with the help of Creo. It is really easy to
build it with Creo. Here I can define different conditions, for example that this part has
to be parallel to this level. I can easily place this part in the right position. Here
I can define the distance, or if it should be parallel or have an angle and easily, the
catch is fixed. With the new array, you can find the commands quickly without long search
efforts or wasting time. With the new 3D Dragger you can join everything together or move parts
without any problems. I am Oliver Würfele, I am a CAM software
engineer at Dannoritzer Medizintechnik and my job is to create CNC programs with the
Creo complete Machining Extension for our CNC machines. Now I would like to show you
an example of this task: Here we have a water-jet cutting part as we
get it from our suppliers. My task is the complete processing with the CNC machines.
With Creo I define operations with which I can finish production completely and that
the product looks like this. Here I have uploaded the complete assembly and I constructed the
clamping fixture the same as the whole clamps. Here we have the SVF2, this is the machine
I just defined. With the next step, a default template is opened, it´s this one here. This
one is standardized because we work with a zero point clamping system. Over the integrated
library, I build a clamping fixture on top of the zero point clamping and then I place
the part here. This is what I made here and in the same way I would clamp it on the machine.
Now you can see different adaptions are defined and this is how it starts: We already defined
drive curves, the straight lines you can see here. They are there to help the milling tool
for orientation and then you can continue to mill along. If you already defined a milling
operation with Creo, you then have the possibility to simulate the tool path as well as the option
to stop the tool in case of collision. Now, the post processor has translated the CNC-program
in the machine code, the machine can assimilate the program right away. Last but not least,
the program is getting uploaded and the milling can be started.
As a small and medium enterprise, we have to face lots of challenges. To grow in the
market we must develop a new factory building, but likewise we want to use the latest CAD
system from INNEO, to ensure we are up-to-date in both a constructive and manufacturing way.
This is how we will safeguard a good future for sure.
