Cellular Manufacturing

When dissimilar equipment and workstations to produce a family of similar components or subassemblies are arranged close together to save space and time, and simplify process routing and supervision. Workers are typically cross-trained to perform multiple tasks within a manufacturing cell.7


Materials comprised of two or more components with significantly different physical or chemical properties, that when combined, produce a material that behaves differently from the individual components. The individual components remain separate and distinct within the finished structure. Examples of engineered composite materials include: carbon fiber-reinforced polymers, metal matric composites, ceramic matrix composites, cement, concrete. Wood is an example of a naturally occurring composite material.

Computer Numerical Control

The digital control of a physical machine that consists of a series of integrated actuators, power electronics, sensors, and dedicated computer running under a real-time operating system. Computer numerical control (CNC) can control multiple machines, usually when they are grouped in a manufacturing cell. This is a form of digital automation.1

Computer-Aided Design

"Computer-aided design (CAD) is the use of a wide range of computer-based tools that assist engineers, architects, and other design professionals in their design activities. It is the main geometry authoring tool within the Product Lifecycle Management process and involves both software and sometimes special-purpose hardware."1

Computer-Aided Manufacturing

In general, computer-aided manufacturing (CAM) refers to "the use of computer systems to plan, manage, and control the operations of a manufacturing plant through either direct or indirect computer interface with the plant's production resources."1 Computer-aided manufacturing (CAM) often refers to software that takes the geometric design authored with CAD software as input and outputs manufacturing instructions that are downloaded to automated equipment such as a computer numerically controlled (CNC) machine tool. Is also referred to as computer-assisted manufacturing.1

Computer-Integrated Manufacturing

"An approach to integrate production-related information and control entire production processes, automated lines, plants, and networks by using computers and a common database."1

Continuous-Flow Manufacturing

A manufacturing method in which the materials (dry bulk or fluids) that are being processed are continuously in motion, undergoing mechanical, thermal, and/or chemical treatment. This is the opposite of batch production. Synonyms include: continuous manufacturing, continuous processing, continuous production, and continuous flow process.8


Coronavirus (COVID-19) is an illness caused by a virus that can spread from person to person. The virus that causes COVID-19 is a new coronavirus that has spread throughout the world. COVID-19 symptoms can range from mild (or no symptoms) to severe illness.


Training employees in several skill sets so they can fill in for one another as needed.

Digital Manufacturing

Aims to improve product design and manufacturing processes across the board seamless integration of information technology systems across the supply chain. Digital manufacturing focuses on reducing the time and cost of manufacturing by integrating and using data from design, production, and product use; digitizing manufacturing operations to improve product, process, and enterprise performance, and tools for modeling and advanced analytics, throughout the product life cycle.

Discrete Manufacturing

Producing finished products that can be recognized as distinct physical units via serial numbers or other labeling methods.

Flexible Manufacturing System

Integrated group of manufacturing equipment and/or cross-trained work teams that can produce a variety of parts in the mid-volume production range. Flexible refers to the systems capability to manufacture different part variants and production quantity can be adjusted in response to changing demand.1

Industry 4.0

A term coined in Germany, popularly used in Europe, and equivalent to smart manufacturing. See Digital Manufacturing.


Just-in-time (JIT) techniques reduce setup times, inventory, and waste, and improve products and reduce manufacturing cycle time. Synonyms include: continuous-flow production. JIT is a total manufacturing system that was first introduced by Toyota Motor Corporation.1


Practice of focusing on continuous process improvement.9

Lean Manufacturing
