Aerospace Manufacturing
When dealing with titanium or HRSAs, use precise
high-pressure coolant to reach the high-heat area
of the cutting zone. Creating a parallel hydro laminar
flow with high velocity not only helps remove
the heat but also assists in breaking chips. (Image:

ting efficiency on a single machine to
throughput and maintenance across the
entire production.
Running dynamic tool paths in
five-axis machines takes more upfront
planning to be sure the cutting operation
goes smoothly. Using smart verification
software, shops can model the
operation and verify there won't be a
collision during machining. There are
also physics-based software systems that
can analyze the cutting force of your process
and adjust cutting data to optimize
efficiency. If you're working a dynamic
tool path on a corner, for example, the
software will determine where the peaks
and valleys are in the forces of your cut
and make adjustments.
Machining operations can also take
advantage of new sensor-equipped
turning adaptors and driven tool holders
to improve predictive maintenance
and metal cutting efficiency. Smart tool
holders can gather and transmit data via
Bluetooth to a computer or tablet. Operators
can now monitor temperature,
vibration and rpm in real time, giving
them information to optimize cutting
speeds and make better decisions about
proactive maintenance planning.
When machining deep bores, sensorized,
dampened turning adaptors
provide similar real-time data

to improve setup times and machine
utilization. For example, a digital center-height
indicator lets operators set
up their boring bar faster and more
precisely. And during the cut, real-time
data on temperature, vibration and
tool load via Bluetooth can be leveraged
in manned and unmanned operation
to improve metal removal rates
and overall productivity.
Data from these solutions can also tie
into a plantwide system for overall production
efficiency. Some tool providers
offer advanced data analytics software
that can aggregate and analyze real-time
machine data and provide actionable
insights for more strategic decision making.
This type of software can be used by
everyone from operators to production
managers to optimize manufacturing
processes, increase machine utilization
and improve profitability.
5. Leverage the Expertise of Your Tool
Provider
The final piece of advice for aerospace
workshops today is to remember that you
are not on your own. Like many shops, if
you're struggling to find skilled resources,
leveraging a partnership with a tool
provider can be an effective way to fill the
gaps. The right provider can offer expert
guidance in everything from workforce

training and CAM support to application
engineering and machining trials.
When considering new partnerships,
look for tool providers who know the
aerospace industry inside and out and
who have the engineering background to
prove out better manufacturing processes.
Some providers have invested heavily in
their own manufacturing environments
so they can run advanced machining trials
and support research and development
for customers. A provider who knows the
industry will also be able to offer more
useful training. Look for training programs
that focus on complete aerospace
component solutions rather than specific
tools. Your team will extract far greater
value from an application-specific course
that covers everything from tooling strategy
to techniques to materials.
Working with a global supplier that's
committed to advancing aerospace manufacturing
will give you the support and
service you need to optimize your processes
moving forward. They'll have the
experience and know-how to help you
solve your toughest aerospace challenges.
