In this study, quality assurance and automatic process control are
combined with a Virtual Reality enabled man-in-the-loop system.
Increasingly flexible manufacturing demands increasingly flexible
process control. Autonomous smart manufacturing systems increase the
amount of tolerable variation in manufacturing processes by reacting to
minor changes in part positioning, preparation, and other issues by
adaptive process parameters. Due to unforeseen circumstances or high
variation, there may be workpieces requiring human interaction to
continue manufacturing, repair, or be sent to recycling or even waste.
Human-robot collaboration may be achieved by safety systems allowing the
human operator within the working area of a robot, or then augmented or
virtual reality may allow a human operator to assess the situation
remotely. The AR and VR technologies may include information usually
invisible to the operator. In this study, a 3D workpiece is measured,
and defects are visualized in a VR environment, focusing on the
geometrical distortion of the workpiece. Measurement had a standard
deviation of +/- 0.067 mm for the root gap. Visualization facilitates
rapid human feedback in case distortion is getting out of bounds. A
man-in-the-loop system is used to provide adjustments to the robot
