The great benefit of simulations

When a new machine was being built for loading raw glass in cold
post-processing at the end of 2021, it was the first time that a team of
Schott experts had used a comprehensive simulation instead of working on the
machine directly. For some time, Schott has been converting selected machines
to “digital native CNC,” better known as Sinumerik One from Siemens
For the first time, Schott has linked
numerous simulation tools together prior to building a new machine. Before
the loader of raw glass in the ceramic glass cooktop production process was
actually built, Schott used digital twins to simulate engineering and control
as well as a behavioral model, kinematics, and machine commissioning.
For engineering, Schott immediately opted
for the Create MyVirtual Machine /Operate software, which automatically meant
a virtual Sinumerik One. This eliminated the need for a real hardware
controller because the virtual Sinumerik One already has the Simatic
S7-PLCSIM Advanced software – making it possible to generate virtual
controllers for simulating an S7-1500 or ET 200SP CPU and use them for the
comprehensive simulation of functions. All that was needed was a simulation
computer to shift the work to a purely virtual environment.
But Schott took simulation even further. This project was the first time that
the company linked its existing and proven Process Simulate robotics
simulation software to Create MyVirtual Machine /Operate software, which was
new to Schott.
Simit software from Siemens – which had
already had a long track record at Schott – served as the link between Create
MyVirtual Machine /Operate and Process Simulate.
A virtualized CNC system makes work faster,
more flexible, and better overall because all of the machine’s functions and
feasibilities can be tested ahead of time. Complete virtual modelling of the
development process significantly shortens product development time while also
speeding up commissioning. Collaboration within the team also took on a new
facet because the digital twin of engineering creates a virtual basis for
discussion where all the disciplines can easily be consulted before the real machine
is built. Machine concepts and functions can be systematically discussed
beforehand. This reduces the risk of misdirected investments as well as a
dependence on available hardware or free test racks.
The Process Simulate 3D simulation platform from Siemens is a technology market
leader for robot and plant simulations. In addition to basic functions for
geometry simulation and offline programming, Process Simulate has an abundance
of functions for modeling plants and controllers as realistically as possible
on one platform. For example, Schott was able to pre-test whether the machine’s
layout would fit in the available space, whether there would be a risk of
collision, and whether the exacting cycle times could be achieved. Using the
geometry simulation and layout planning in the simulation system, it was
possible to reduce the functional risks in machine operation to a minimum. Even
before the machine was built, Schott was able to ensure the concept and
acquaint itself with all the functions.
Mainz, Germany For more than 50 years, ceramic glass cooktops from Schott have remained
bestsellers thanks to a range of technical properties. Not only are the
cooktops made exclusively from sustainable natural materials but they also
withstand high temperature differences and thermal shocks. In addition, they’re
an extremely robust product with high chemical resistance. Numerous awards
attest to their extremely high quality in all areas, including four German
“Brand of the Century” awards in 2013, 2016, 2019, and 2022 – so it’s even more
interesting to learn how Schott is able to guarantee this quality level day
after day.
It’s possible to produce large batches of increasing complexity and
variety only if the process works consistently on the highest level.
