Minimizes residual stress and thermal damage.
First, Elias experimented with the Mechanical approach. He didn't use a drill bit; he used sound and water.
By the end of the project, Elias had achieved a level of accuracy and surface finish that his old drills could never match. While these modern methods were slower (lower material removal rate), they made the "impossible" parts for superalloys and carbides possible.

Non-traditional machining, sometimes called modern machining, leverages specialized energy sources to remove, deform, change, or plate materials. These methods are employed when traditional, force-driven methods are impractical or inefficient. Minimizes residual stress and thermal damage
A voltage difference is applied between the tool and the workpiece. When the breakdown voltage of the dielectric fluid is reached, a spark jumps across the spark gap, melting and vaporising a tiny crater of material.
Next, he looked at Thermal and Electrical methods. With Electrical Discharge Machining (EDM) , Elias used controlled electric sparks to "melt" away the metal. There was no contact, meaning no mechanical stress on the delicate part. By the end of the project, Elias had
| Parameter | Conventional | Non-Conventional | |-----------|--------------|------------------| | Tool contact | Yes | No | | Material hardness | Limiting factor | No issue | | MRR | High | Low to moderate | | Surface finish | Good | Excellent (except thermal) | | Initial cost | Low | High |
