Application Potential of Thermoelectric Signals for Temperature Monitoring in Turning of Aluminum Alloys

Temperature measurement close to the point of its origin is of great importance during chip removal. Therefore, two different temperature measurement methods are used and compared with each other for turning of the aluminum alloy EN AW-2017. On the one hand, cutting temperatures are measured by three thermocouples embedded in the indexable insert. On the other hand, the temperature in the contact area of the tool and the workpiece is detected by a tool-workpiece thermocouple measuring the thermoelectric voltage resulting from the Seebeck effect. For the experiments the cutting speed remains constant while the depth of cut and the feed are varied.
