Thermal cutting process
Thermal cutting is one of the most important production processes in the metal producing and metalworking industries (e.g. structural, fabrication, shipbuilding and plant manufacturing etc).

Thermal cutting primarily is use of energy in various forms to cut virtually any shape from iron and nonferrous materials out of sheets or slabs which are usually referred as “Flats” in the metal processing industries. The other type of metals is available in angle etc. which are called as “Longs”.

Type of material to be cut and its thicknesses
The selection of thermal cutting process would primarily be depending upon the type of material ferrous, nonferrous and its thicknesses.

Tolerance of cut parts
The tolerance of the various types of thermal cutting processes is each dedicated to the process basics, expressions, quality and dimensional tolerance. The quality characteristics, perpendicularity and angularity tolerances and the permissible calculated depth of roughness are set separately for the different cutting.

Physics of the cutting process and its effects on the material
One can distinctly separate the cutting by physics, which can be burning (chemical reaction) by oxidation, melting and vaporisation. The selection of the process would make an effect on the type of the material to be cut, tolerances, chemical and physical reaction post cutting.

Type of production
In various industries the type of production is categorised as cutting by manually operated tools, semi-mechanised cutting, fully mechanised cutting and automatic cutting. The volume of the production can also have a bearing on the selection of the process.

Post cutting operations desired
The thermally cut parts which are parted from the mother plate are taken for the post cut operations. In some of the operations there would be direct fitment, welding, grinding or bending, heat treatment etc. The process is greatly influenced by the post cutting operation desired.

Energy carrier
The energy carrier is terminology used for metal removal; it can be hot gases, electric gas discharge or by beam energy like light. The usage of various energy carriers has direct implication on several physically and mechanical effects on the cut parts.

Application of the cut part
The application of the cut parts can be explained to understand whether the part is subjected to mechanical stress, chemical reaction or fatigue etc, this would directly determine the thermal cutting process to be used.
