uality control is fundamental
in every industry, but in manufacturing it's hyper-critical.
Volatile market demand, high
material and production costs, alongside
the mission-critical nature of end
products, impel manufacturers to pursue
nothing but first-rate quality and a
minimal rejection rate. With the Internet
of Things (IoT) gradually hitting its
stride across the manufacturing industry,
quality management is an area with
transformational opportunities.

Q

The Quality Management Challenge
at a Glance
Effective quality management relies
on the ability to constantly monitor and
control a host of machine and process

parameters that impact product quality.
To ensure product properties are consistent and up-to-par, equipment recalibration is constantly performed as
process drifts and other changes in the
production line crop up. Yet, with the
growing complexity of tooling systems
and manufacturing processes, many
process variables are left unattended
due to the limits of bulky wired networks.
While ideal for high-throughput, timesensitive automation tasks, wired communications lack the flexibility and
affordability needed to capture telemetry
data at scale and beyond the machine
level. Typically, factors like environmental conditions, despite their major influence on quality variability, are often not

studied and controlled. For example, in
auto manufacturing, unfavorably low
room temperature can reduce the quality
of 3D printed components by causing
them to cool too quickly.
What's more, designed in the last century, the majority of wired-driven industrial systems aren't intended for data
exchange beyond the factory floor. This
creates disconnected islands of data that
aren't available to enhance production
efficiency and throughput. Instead,
process optimization and quality management often depend on reactive, manual
post-production inspection. Besides
expensive human intervention, this introduces significant quality variability and
associated costs, while making it challenging to trace the root cause of quality issues.
