| CNC |
Computer Numerical Controlled |
| CNC Machining |
An automated form of machining that results in increased productivity and flexibility |
| CNC Milling |
Tools used to machine solid materials in either a vertical or horizontal form |
| CNC Turning |
A single point cutting tool used parallel to the rotating surface to shape a metal die |
| Contract Electronic Assembly |
Purchasing electronic assembly services from a third party for use in own products or services, or using a third party to input electrical connections into a mechanical assembly for own purposes |
| Contract Machining |
Purchasing machining services from a third party for use in association with own assembly, product, or service |
| Die Casting |
Forcing molten metal under high pressures into reusable molds which can then be formed into a variety of shapes |
| Electro-mechanical Assembly |
Adding electrical connections to a mechanical assembly |
| Ferrous Materials |
Metals or alloys containing iron: e.g. stainless steel, carbon steel, pig iron |
| Forging Machining |
Placing a plate of metal between two parts of a mold and forcing into position |
| GMAW |
Gas Metal Arc Weld; also known as MIG (Metal Inert Gas) Welding |
| GTAW |
Gas Tungsten Arc Welding; also known as TIG (Tungsten Inert Gas) Welding |
| Heat Treating |
Using extreme temperatures to heat or cool a metal; this makes the metal harder or softer which alters the physical/chemical properties of the metal |
| Heatsink |
Using thermal contact to absorb or dissipate heat from an object |
| Heliarc Welding |
Another word for GTAW or TIG Welding |
| Impact Extrusion |
Process in which a slug is placed in a die cavity, pressed at high velocity with extreme force by a punch, creating a metal mold |
| ISO |
International Organization for Standardization, sets the international industrial and commercial standards for all forms of manufacturing and services |
| Machining Vises |
manufactured as either hydraulic or manual, zero-point clamping, numerous models are available for general purposes, high density, or specialty reasons |
| MIG Welding |
Automatic arc welding process where a wire electrode and shielding gas are fed through a welding gun, also known as Gas Metal Arc Welding (GMAW) |
| NADCAP (Nadcap) |
National Aerospace and Defense Contractors Accreditation Program; sets the manufacturing standards for the aerospace and defense industries |
| NDT |
Nondestructive Testing; testing the property of a metal without causing any damage, a cost-effective evaluation |
| Non-ferrous Materials |
Metals or alloys that do not contain iron: e.g. aluminum, copper, titanium |
| PMA |
Parts Manufacturer Approval; granted by the United States Federal Aviation Administration (FAA), giving permission to a manufacturer to produce aircraft parts |
Precision Machining
(CNC Precision Machining) |
Precision CNC machining is a loosely used term to describe CNC machining to very close tolerances. |
| Prototype Machining |
Manufacturing one component or a few parts to ensure accuracy of the design and dimensions |
| Robotic Welding |
The use of robots in the welding process to complete the entire weld |
| Screw Machining |
Either CNC or mechanically automated, used in high volume manufacturing, creates small, turned parts |
| Short Run |
A low cost, time limited form for production |
| TIG Welding |
most commonly used for stainless steel and non-ferrous metals, arc welding process that uses a tungsten electrode to produce the weld, also known as Gas Tungsten Arc Welding (GTAW) |
