Dinking: Cutting of non-metallic articles from the sheet, usually involving such operations as blanking and piercing. (Ramalingam K.K., Handbook of Mechanical Engineering Terms, 2nd edition, p. 55)

Fullering: Similar to drawing and is a preliminary forging operation which results in an elongated section between two heavier sections. (Ramalingam K.K., Handbook of Mechanical Engineering Terms, 2nd edition, p. 58)
Heading: A metal gathering or upsetting operation. Originally used for production of screw and rivet heads in cold working process. (Ramalingam K.K., Handbook of Mechanical Engineering Terms, 2nd edition, p. 58)

2d laser processing systems: The 2D laser systems are used mainly for cutting, welding and hardening operations. The first industrial laser systems, the so called laser machining centers were occupied with a fixed beam delivery system. The workpiece was positioned relatively to the laser spot. Typical applications were turbine blade drilling, contact welding, etc. Nowadays, the laser systems available, can be used either as flexible manufacturing cells or as fully automated components of a production chain. (Chryssolouris G. Manufacturing Systems, 2nd edition, p. 158)
3d laser processing systems: The primary aspect of the 3D laser processing with two converging laser beams is the laser grooving process. Each beam creates a groove in the workpiece through single or multiple passes. A volume of material is removed when the two produced grooves intersect. Turning, milling and gear cutting operations can be accomplished with the use of this system. (Chryssolouris G. Manufacturing Systems, 2nd edition, p. 159)
Cupola: Special type of blast furnace, chiefly used for the melting of cast iron. (Ramalingam K.K., Handbook of Mechanical Engineering Terms, 2nd edition, p. 70)
Governor: A device for controlling the speed of a prime mover, that produces power. (Ramalingam K.K., Handbook of Mechanical Engineering Terms, 2nd edition, p. 71)

Pickling: Treatment of objects with an acid solution to remove all oxide, scale or dirt. Usually done to clean and brighten the surface, although sometimes used for etching. (Ramalingam K.K., Handbook of Mechanical Engineering Terms, 2nd edition, p. 144)
Seaming: A bending and flattening of an interlocking fold, e.g., a stove pipe seam. (Ramalingam K.K., Handbook of Mechanical Engineering Terms, 2nd edition, p. 62)

Thermit: Powdered form of finely divided iron oxide and aluminium which burns intensely to produce superheated liquid steel at a temperature of about 30.35°C, used for welding wrought iron and steel forgings and castings. (Ramalingam K.K., Handbook of Mechanical Engineering Terms, 2nd edition, p. 36)
