Analyze MyWorkpiece /Toolpath, where it
can be visualised and analysed. The
recorded position data can be used to
reconstruct a 3D representation, and
additional measurement values can also be
depicted through colour coding, which can
support display of deviating path velocities.
Fundamentally, the applications enable
target data – generated for instance by CAM
– to be compared to data recorded during
the actual process.
The resulting fi ndings enable optimisation
of CADCAM models and the generated NC
program, so Analyze MyWorkpiece /Toolpath
helps deliver right-fi rst-time workpieces.
Overall improvement in process quality and
process development are the key benefi ts.
Analyze MyMachine /Condition captures
a mechanical fi ngerprint of the machine tool,
taking in such things as rigidity, friction and
reverse backlash in the individual axes. By
visualising the measured results and
comparing them to reference data, machine
tool condition transparency is delivered. The
early identifi cation of non-conformance
allows optimised machine operation and
reduced machine downtime. Conditiondependent
maintenance also makes for
optimised processes and cost savings,
These latest applications join Optimize
My Machining /Trochoidal. This updates
existing NC programs, providing optimised
machining processes, using dynamic
machine data and corresponding data
inputs. It is particularly suitable for use with
older machines, as it reduces the
mechanical wear in the machine.
OPTIMISED MILLING IN REAL TIME
Not at the Hanover Messe but probably a
feature of the forthcoming EMO exhibtion in
September, in similar vein to that last offer
from Siemens, tooling expert Walter
(https://is.gd/xowamo) offers its Comara
iCut software tool, which also makes use of
real-time analysis of machine data.
Integrated into the machine control
(Siemens 810D and 840D), iCut measures
a machining centre’s milling spindle output
up to 500 times per second and
automatically adapts the feed to the cutting
conditions (video: https://is.gd/okahoc).
If the cutting conditions change, perhaps
owing to varying contact angles and depths
of cut, fl uctuations in allowance or due to
signs of tool wear, iCut adapts the speed
and output in real time – and the resulting
optimised milling increases process
reliability while boosting production output
by at least 10%, Walter says.
In addition, the forces on the spindle are
more constant – which increases its service
life – and if the tool is in danger of
breaking, iCut immediately reduces the
feed or stops the action.
Comara has also developed the appCom
software platform to make all the data
generated during the machining process
usable for process optimisation. Comara
appCom comprises two components: a PC,
which is installed in machines and
integrated in the control system; and the
software, which analyses and displays data.
Walter uses the app principle for this
and even the basic version of appCom
features more than 13 apps, which can be
used to collect and monitor parameters
including machine status, productivity and
the stability of the programs being run.
Company-specifi c apps can also be
programmed and displayed. appCom users
see a signifi cant increase in productivity
and process reliability, says the cutting tool
5G mobile industrial trials
The UK’s fi rst 5G mobile factory trials are being undertaken in Worcester, in a project
that includes machine tool maker Yamazaki Mazak. This is part of the Worcestershire
5G Consortium, which received £4.8 million to test a number of 5G applications.
As we reported last year (https://is.gd/ocucaw), according to the EU Commission’s
‘5G for Europe: An Action Plan document’: “5G is seen as a game-changer, enabling
industrial transformations through wireless broadband services provided at gigabit
speeds.” And Qualcomm explains that while local area networks based on ethernet,
WiFi and LTE (4G mobile) are already used in industrial applications, 5G allows users to
“confi gure the network to exactly the performance it requires”, adding “industrial
networks can be designed and optimised for real-time performance, extreme reliability
and availability, and for stringent privacy and security restrictions”. Qualcomm is a world
leader in 3G and next-generation mobile technologies.
The Worcestershire group in total takes in experts from the University of Surrey,
AWTG, Huawei, O2, BT and Malvern Hills Science Park, plus gas boiler maker Worcester
Bosch and Yamazaki Mazak. Worcester Bosch is looking to 5G to deliver improved
factory output, exploring preventative maintenance utilising IoT sensors and data
analytics to predict failure.
Yamazaki Mazak will demonstrate how 5G can be used to boost factory productivity,
employing the technology for two troubleshooting applications, one of which will see
engineers remotely guide onsite engineers through machine maintenance.
