Glossary of Terms

Assemblies
The putting together of complex components and machinery for completion.
Batch Processing
A technique used in manufacturing, in which the object in question is created stage by stage over a series of workstations. With job production and flow production it is one of the three main production methods
Burr
A rough edge or ridge left on an object (especially of metal) by the action of a tool or machine.
CNC Milling
CNC is short for Computer Numerical Control -it refers to a computer "controller" that reads instructions and drives the machine tool. CNC's are able to perform precision cuts reliably in machine shop settings. Most machine shops would have CNC lathes, CNC routers, CNC milling machines, etc.
CNC Turning
Turning is a machining process in which a cutting tool, typically a non-rotary tool bit, describes a helical toolpath by moving more or less linearly while the workpiece rotates.
Cutting
The action of cutting something.
Extruding
The turning up or drawing out of a flange around a hole which has been punched in a previous operation. Also called hole flanging.
Fabrication
The action or process of manufacturing or inventing something.
Fillet
The concave intersection of two surfaces. In forging, the desired radius at the concave intersection of two surfaces is usually specified.
Finish
If only one finish operation is scheduled to be performed in the finish die, this operation will be identified simply as finish; first, second, or third finish designations are so termed when one or more finish operations are to be performed in the same finish die.
Flattening
A preliminary operation performed on forging stock to position the metal for a subsequent forging operation.
Flex Roll
A movable roll designed to push up against a sheet as it passes through a roller leveler, which is adjusted to deflect the sheet any amount up to the roll diameter.
Forming
To make changes in the shape of a metal piece which does not intentionally reduce the metal thickness and which produces a useful shape.
Gage
The thickness of sheet metal or wire.
Grinding
To crush, pulverize, or reduce to powder by friction, especially by rubbing between two hard surfaces.
ISO Certification
ISO 9001 is an international standard that gives requirements for an organization's quality management system (QMS).
Key
A block partially mounted in a pocket at the perimeter of a die member to locate, add support, and/or back up that die member. It is accessible without removing the die member
Laser Cutting
Laser cutting is a precise method of cutting a design from a given material using a CAD file to guide it.
Piercing
The general term for cutting (shearing or punching) openings, such as holes and slots, in sheet material, plate, or parts. This operation is similar to blanking; the difference is that the slug or piece produced by piercing is scrap, while the blank produced by blanking is the useful part.
Press
A machine having a stationary bed or anvil and a slide (ram or hammer) which has a controlled reciprocating motion toward and away from the bed surface and at right angle to it. The slide is guided in the frame of the machine to give a definite path of motion.
Quality Management System
A quality management system (QMS) is a collection of business processes focused on achieving quality policy and quality objectives to meet customer requirements.
Sheet
Any material or piece of uniform thickness and of considerable length and width as compared to its thickness
Stretch Forming
The shaping of a sheet or part, usually of uniform cross section, by first applying suitable tension or stretch and then wrapping it around a die of the desired shape.
Sub Contract Services
A subcontractor is an individual or business that perform part or all of the obligations of another's business contract.
Tolerance
The permissible deviation from a specified value of a structural dimension, often expressed as a percent.
Welding
To join (metals) by applying heat, sometimes with pressure and sometimes with an intermediate or filler metal having a high melting point.
