If you attend IMTS, you will see a lot about Industry 4.0 and IIoT. Basically, it is using sensors to monitor a machine and collect data on its processes. There is some real value there, but what if you have a sub-optimal process?
You will be able to calculate OEECP (Overall Equipment Effectiveness of a Crappy Process).
Machine tools are not yet self-healing, although there are products like Caron's TMAC and Okuma's NAVI that will adjust feed rate or speeds and probes can update offsets. But, the distance between cruise control and fully autonomous cars is still quite large. Today, sensors cannot take a bad process and automatically make it a good one. Monitoring is reactive and there is still need to be predictive.
We cannot yet replace the skills needed to select the correct tool components, assemble and balance it correctly, find its optimum operating parameters and build the correct fixturing. We are using science (and yes, sensors) to help improve set-up and deliver optimized milling processes to be monitored. Gee, I guess we ARE Industry 4.0.
