DMG MORI DELIVERS SUPERIOR MACHINING ACCURACY AND EQUIPMENT WITH PTC CREO AND

DMG MORI DELIVERS SUPERIOR MACHINING ACCURACY AND EQUIPMENT WITH PTC CREO AND
WINDCHILL

DMG MORI decreased their concept-to-production time by 16 months through using
PTC's CAD solution to transition to 3D product development and collaborate more
efficiently. 


CHALLENGES

With increased pressure from low-cost machine shops, DMG MORI must innovate to
deliver the highest machining accuracy and the latest machining equipment.

> Dr. Hans Gronbach, head of R&D at DECKEL MAHO


THE CHALLENGE

Metalltechnik Vils, based in Vils, Austria, is part of a family business that’s
been operating for more than 100 years. The company machines parts for some of
the world’s sexiest clients: Bosch, Georg Fischer, Trumpf, Swarowski, AGCO and
Kuka.

But just like everyone else, the team must compete as pressure increases from
low-cost machine shops. To discover how the company does it, look at the name on
the shop floor: DMG MORI, a PTC customer.




THE SOLUTION

DMG MORI is the brand of DMG MORI SEIKI AKTIENGESELLSCHAFT, a global
manufacturer of machine tools, turning centers, lathes, ultrasonic and laser
machines. The German DMG MORI SEIKI group includes companies like DECKEL MAHO,
GILDEMEISTER, GRAZIANO, SAUER and FAMOT.

Metalltechnik Vils’ most recent purchase from DMG MORI is the DMC 80 U
duoBLOCK®, a 5-axis milling center for complex parts. “The duoBLOCK® is the best
out there,” says Christoph Allgaier, commercial director for the company. “We
can now maximize our capacity. Plus we respond to changes in orders quickly and
flexibly within one day. This used to take us anywhere from one to two weeks.”


CREATIVITY

The latest generation of the DMC 80 duoBLOCK® is packed with new features: large
traverse paths, higher table loads, and a high-capacity tool changer. The
designers also included a fast, space-saving pallet changer and a large work
area to set up large, multiple clamping devices or machine large parts.

DMG MORI’s quality, precision and speed to market required the right design
tools. And according to Dr. Hans Gronbach, head of R&D at DECKEL MAHO, that
required PTC Creo.

“We were the first company to offer 5-axis machining, and today deliver the
highest machining accuracy and the latest machining equipment. The pace of
innovation we reach today is only possible with PTC Creo and PTC Windchill.”


PRODUCTIVITY

In the machining world, productivity is measured in terms of reliable precision,
meaning that a machining center must machine parts within a couple of microns
every single time. Reliable precision is often based on the rigidity, or
stiffness, of the machine.

With PTC Creo Simulate, the latest duoBLOCK® design is optimized in terms of
dynamic and static masses. “We have reduced the dynamic mass (mass of moving
parts) by 50% and increased the static mass. This results in higher stability,
long-term precision and lower overall energy usage,” says design team lead
Roland Köchl.

PTC Creo enables 3D virtual prototyping so designers like Köchl and his team can
test a range of structural properties of the duoBLOCK® early in the detailed
design process and before making even the first physical part.

The bottom line? The team verified and validated its duoBLOCK® design early in
the design process with fewer physical prototypes and produced a superior
machine.


TEAMWORK

Multiple designers work on the development of a new machine and are responsible
for different parts of the overall machine. Typically, each machine is divided
into eight major subassemblies, like the automatic tool changer or the milling
head.

With PTC Creo and using top-down design, each designer can evolve a subassembly
concurrently in 3D, load the changes to assess daily progress, and identify and
resolve issues instantly.
“By using PTC Creo and its validation capabilities,” says Köchl, “we can check
that both static and moving parts don’t clash or touch each other. That helps us
cut back on physical prototypes. Plus, PTC Windchill ensures the team is working
on the latest designs, and that all changes are tracked.”

With PTC Creo, the engineering team no longer needs to create 2D technical
drawings. “There’s no need for them,” says Reinhard Musch, head of manufacturing
for DECKEL MAHO. “The 3D model is significantly easier for teams to understand,
is precise, and can be directly used for manufacturing – it’s very efficient.”


FLEXIBILITY

The latest generation of the automatic tool changer in the duoBLOCK® is based on
a multiple wheel design, holding up to 400 machine tools and enabling tool
swapping in just one second. A split-second 400-tool changer could never have
been realized earlier – R&D time and costs would have been exorbitant.


RESULTS

By abandoning their old 2D-based approach and switching to PTC Creo, the machine
traveled from concept to production in just 14 months (shaving 16 months off
their previous release times). With improved accuracy and long-term precision,
the duoBLOCK® is the highest performing center with the smallest footprint to
date.

There were three benefits that saved the team the most time: early and constant
3D design validation and reviews, fewer physical prototypes, and sending the 3D
model to manufacturing and partners.

For companies like Metalltechnik Vils, a great machine like the duoBLOCK® means
more business. And a full order book means security for the next 100 years.
