Real-Time Monitoring and Control of Machining Accuracy in CNC Machining Centres

During machining operations on machining centres, there are a large number of internal and external factors that act on the technological system. The monitoring and control system developed for machining centres presented in this paper consists of 3D touch probes, a device for registering a contact between the cutting tool and workpiece, devices for measuring the geometric accuracy of the machine tool and for calibrating the touch probe in the spindle, parameterised CNC programmes, computer and software for data processing and database management.
