Inducing high thermal loads in machining of difficult-to-cut materials changes the mechanical properties of a machined surface/subsurface. In particular, a thermally affected layer leads to tensile residual stresses and microstructure changes. Nickel-based alloys are hard materials and frequently used in different industries.

Nontraditional Machining and Thermal Cutting ­ Chapter 26 ...

Thermal Machining Thermal machining removes materials by melting or vaporizing the work piece material. Many secondary phenomena occur during machining such as microcracking, formation of heat affected zones, striations etc. The source of heat could be plasma as during EDM and PBM or photons as during LBM, electrons in EBM, ions in IBM etc.

Introduction to Non

Electron Beam Machining (EBM) – Modern Machining Process. Electron Beam Machining (EBM) is a thermal process. Here a steam of high speed electrons impinges on the work surface so that the kinetic energy of electrons is transferred to work producing intense heating. Depending upon the intensity of heating the work piece can melt and vaporize.
