b'Bosch Rexroth Bosch Rexroths analytics system (above) can determinequickly and accurately whether a part is good, eliminatingthe need for manual inspection.On a screen, Redax users (left) can see at a glance how all their grinding machines are operating.by operators clicking on Amazon Dash buttons to sig-nal whether each drilled part was good. By matching labels and vibration information produced at different times during machining, the team was able to teach the neural network which vibration data indicated a bad part (one with a chip in the cavity) and a good part (one with no chip in the cavity), as well as the type of tool used in the machining operation.Downloaded to the edge device, the neural network can evaluate parts almost instantaneously as theyre machined, Dariol said. The system has been running for more than two years and has become more accurate over time thanks to continuous data collection.Now we produce 1% or less false positives and false negatives, he said. So our customers are really trust-ing the results they are getting from our system.CTEctemag.com/cteguide.com61MachineControl.indd 61 7/17/20 3:02 PM'
