Technical ceramics machining using traditional machines to remove chips with the help of the laser technology

Objective



The present study aims at studying a new machining process of technical ceramics by using a traditional CNC machining lathe. A Nd-YAG or diode laser will be integrated to this lathe for the preheating of the material (A1203, ZrO2, A17r, Mullite) to bring it to a state of plasticity. The ceramics machining by chips removal should give machining results of about 20 to 30% higher with an increase of the mechanical properties of the finished part. Emphasis will be put on the process control to guarantee the obtention of the final machining dimension while taking into account the thermal expansion of the material due to the laser heating. A prototype of the machining machine including a laser beam handling system of 5 free degrees and guaranting a good tests reproducibility will be made by IREPA LASER At the same time a process control system will be finalized by FHG-IPT to adjust to the depth of pass of the tool according to the material expansion.
