Abstract

An innovative anthropomorphic robot laser is described. The beam is transmitted from the source to the sensorized focusing head by a chain of flat high reflective mirrors, located inside the robot structure. This machine can be joined to whatever laser source up to 8 kW and is able to perform cutting, welding and heat treating processes mainly by changing the final optical head. In order to obtain constant and repeatable results, during laser processing, it was necessary to develop suitable sensorized systems. The paper treats the activity and results obtained in the first phase of the research where the feasibility of a new sensorized head, for controlling hardening process, has been experimentally tested. The statistical methodology 'Parameter Design' was used in order to obtain an accurate analysis over the process field. Several tests have been performed both in oven and with laser beam. A good correlation between sensor signals and case depth was found. A prototype of optical head will be presented.
