Jan 01, 2011 Thermal machining processes are manufacturing processes that use a heat source to remove material (Benedict, 1987).Traditionally, these processes have been included in the non- conventional process group because they remove material by melting or vaporization generated by a heat source instead of using mechanical methods such as cutting tools, abrasives, etc.
Oct 01, 2012 Thermal growth is an inherent factor in any machining process. Here's how one company constructs its machines to adapt to changing thermal conditions. Here are the components and basic layout of Okuma’s Thermo-Friendly Concept system for a VMC.
Dimension inaccuracy of work duet to thermal distortion and expansion and contraction during and after machining Surface damage by oxidation, rapid corrosion, burning etc. Tensile residual stresses and microcracks at the surface and sub surfaces. However, often the high cutting temperature helps in reducing the magnitude of the
Thermal cutting processes differ from mechanical cutting (machining) in that the cutting action is initiated either by chemical reaction (oxidation) or melting (heat from arc). All cutting processes result in the severing or removal of metals. Oxygen cutting is accomplished through a chemical

Groover, “Fundamentals of Modern Manufacturing 2/e” Thermal Energy Processes Overview •Very high local temperatures Material is removed by fusion or vaporization •Physical and metallurgical damage to the new work surface •In some cases, resulting finish is so poor that subsequent processing is
The word “machining” is an all-encompassing word that covers many categories, i.e. specific terms, materials, and processes. A Reader’s Digest version of machining would be ‘the mechanical altering of a material by the use of lathe, a mill, or some other type of machining tool in order to create the end product desired’.

Electron beam machining is a thermal process used for metal removal during the machining process. In the electrical beam machining, electrical energy is used to generate the electrons with high energy. In the Electron Beam Machining process, a high velocity focused beam of electrons are used to remove the metal from the workpiece.
Advantages of Machining Process: The advantages of machining process are as follows. A high surface finish can be obtained. Machining is not only performed on the metal but it also performs on wood, plastic, composites, and ceramics. A variety of geometry features are possible, such a Screw threads, Very straight edges, Accurate round holes, etc.
And the components won't necessarily be the same temperature. Parts that have recently come off a dry machining process may be several degrees warmer, and may remain so for hours. Parts machined under coolant may be cooler. The gage or the master might be sitting on a bench in direct sunlight, or under a heating or cooling vent.
