| Summary: | Micro-EDM is a slow process as compared to laser machining, on the contrary laser
machining lacks good surface quality. To overcome the drawbacks of both these
processes, this paper suggests a hybrid machining process which combines laser and
micro-EDM processes for drilling micro-holes in advanced engineering materials such as
Nickel-Titanium (Ni-Ti) based shape memory alloy. To achieve the objective of the
suggested hybrid process, pilot holes are drilled with laser machine and rimmed out by
micro-EDM drilling. The suggested process requires investigation of various
combinations of micro-EDM drilling process conditions to obtain optimum machining
parameters for the hybrid process. It has been found that the proposed hybrid machining
process resulted in 50-65% reduction in machining time without affecting the quality of
micro-holes as compared to the standard micro-EDM process. |
