Objetivo The industrial use of some materials (high strength steels, super alloys and ceramics) is at present limited due to their poor machinability. Preliminary studies on LAM have shown that cutting force reductions of from 20 to 50% have been obtained on Inconel type alloys and high strength steels, resulting in some cases in tool wear reductions of 20%. This has allowed directions for research work to be defined and pursued to optimize LAM. The objective of this project is to provide industry with technological data on materials having different properties so as to give information on machining cost reductions. To reach the target, LAM tests have been carried out, with laser beam analysis (conditions of plasma forming), thermal gradients and vibrations measurements), and completed by optical, thermal and mechanical parametric modelling of LAM. The economic evaluation of LAM processes has been performed through assessment of gains brought by laser assistance during machining, in terms of cutting forces, tool wear, catastrophic tool breakage and vibration reductions, and machined parts quality improvement. Some demonstration parts have been laser assisted machined leading first to demonstrate that the process is applicable on complex shapes and second to estimate part costs. It can be said that during this programme progress has been made in the better understanding of these materials and the machining of them, when assisted by laser. While it is clear that the LAM process is not applicable nor desirable in all machining operations, it is equally clear that under certain circumstances, with certain conditions, LAM is indeed, a process that will produce components quicker and at a lower price.The industrial use of some materials (high strength steels, super alloys and ceramics) is at present limited due to their poor machinability.
