Computer-aided design (CAD) is the use of computers (or workstations) to aid in the creation, modification, analysis, or optimization of a design. CAD software is used to increase the productivity
of the designer, improve the quality of design, improve communications through documentation, and to create a database for manufacturing. CAD output is often in the form of electronic files for print, machining, or other manufacturing
operations. The term CADD (for Computer Aided Design and Drafting) is also used.
A “CNC plasma” system is a machine that carries a plasma torch, and can move that torch in a path directed by a computer. The term “CNC” refers
to “Computer Numerical Control”, which means that a computer is used to direct the machines motion based on numerical codes in a program.
Numerical control (also computer numerical control,
and commonly called CNC) is the automated control of machining tools
Plasma cutting is a process that cuts through electronically conductive materials by means of an accelerated jet of hot plasma. Typical materials cut with a plasma torch include steel, stainless steel, aluminum,
brass and copper, although other conductive metals may be cut as well. Plasma cutting is often used in fabrication shops, automotive repair and restoration, industrial construction, and salvage and scrapping operations.
Due to the high speed and precision cuts combined with low cost, plasma cutting sees widespread use from large-scale industrial CNC applications down to small hobbyist shops.
Tungsten Inert Gas (TIG) welding, is an arc welding process that uses a non consumable tungsten electrode to produce the weld. The weld area and electrode is protected
from oxidation or other atmospheric contamination by an inert shielding gas(argon or helium), and a filler metal is normally used, though some welds, known as autogenous welds, or fusion welds do
not require it. When helium is used, this is known as Heliarc welding [1]. A constant-current bwhelmet produces electrical energy, which is conducted across the arc through a column of highly ionized gas and metal
vapors known as a plasma.
Metal Inert Gas (MIG) welding or metal active gas (MAG) welding, is a welding process in which
an electric arc forms between a consumable MIG wire electrode and the work piece metal(s), which heats the work piece metal(s), causing them to melt and join. Along with the wire electrode, a shielding gas feeds
through the welding gun, which shields the process from atmospheric contamination.
Tube Notching is a metal-cutting process used on sheet-metal or thin bar-stock, sometimes on angle sections or tube. A shearing or punching process is used in a press, so as to cut vertically
down and perpendicular to the surface, working from the edge of a work-piece.
Tube bending is any metal forming processes used to permanently form pipes or tubing. Tube bending may be form-bound or use free form-bending procedures, and it may use heat supported or cold forming
procedures.
