Renishaw
plc, Wotton-under-Edge, Gloucestershire, UK, has launched InfiniAM™ Sonic,
an acoustic process monitoring software to complement its InfiniAM suite of
Additive Manufacturing monitoring tools. InfiniAM Sonic reportedly enables
engineers to detect acoustic events within the AM build chamber and transform
this data into useful information about build quality. The company states that
the software is the first of its kind in the AM industry.

The
InfiniAM Sonic package is installed into Renishaw’s RenAM 500Q system as a
factory fit option and includes four acoustic energy sensors to detect
vibration in the build. The sensors can detect minute vibrations and collect
the sound waves so that they can be heard, viewed and analysed. Using four high
frequency sensors in different locations results in a slight time difference,
due to the speed of sound. The software uses this to triangulate the position
of the noise on the build plate. Additionally, the software presents a level of
certainty regarding where the noise occurred, and the magnitude. This data can
then be combined graphically with other sensor data to build a comprehensive
view of the part and the conditions at the time of build.

According
to the company, InfiniAM Sonic works alongside InfiniAM Central and InfiniAM
Spectral, which provide improved understanding of build quality, increased
confidence in the build process and accelerated process development. The
InfiniAM Central mobile app is also available, so that users can receive
notifications on their build process in near real-time.

“The
rapid heating and cooling that takes place during an AM build leads to residual
stress in the part,” explained David Ewing, AM Product Manager at
Renishaw. “While each laser weld results in a small amount of stress,
residual stress can build up within the part, and if it increases past the
strength of the metal it may lead to a fracture in the support material or part
itself.”

Ewing
continued, “Renishaw’s InfiniAM software suite makes it a lot easier to
understand what is happening during an AM build. Spectral and Central give
manufacturers ‘eyes’ inside their AM component and process – now we’ve launched
InfiniAM Sonic as the ‘ears’. These tools help engineers to better understand
their AM parts and processes, and identify potential causes of defects early
on. This is particularly useful whilst developing and validating parts. The
more data available, the quicker it is to confirm manufacturing is in specification;
root cause investigation is simplified, and if necessary the build can be
stopped, saving material and time.”
