We have been using many traditional machine tools such as lathe machine, drilling machine, shaper machine, etc. in our machine shops. These machines are standalone without any integration with any central computer system or integration with each other. However if we can integrate them with a computer system that will continuously monitor the performance/utilization, maintenance related issues, and help in scheduling them, we will get the massive benefit of advanced machine tools with least investment. So what are the ways we can make these machine a little bit intelligent (?) that will help us in our traditional machine shop? Can IoT/similar technology help us in this case?
