Circuit switching
A method of establishing a dedicated communications path between two or more locations through one or more switching nodes. Data is sent in a continuous stream; the data rate is constant; the delay is constant and limited to propagation times; and a dedicated end to end path remains in effect until the communication is terminated.
Cleanrooms are highly control environments which are sterile and have a highly reduced contamination risk factor such as a dust-free environment.
Cleated belt

Closed circuit voltage (CCV)
Closed-circuit voltage is the difference of electrical potential between two terminals of a device when there is an external load connected.
Closed-loop control
Any system in which part of the output is fed back to the input to effect a regulatory action, and in which the controlled quantity is measured and compared with a standard representing the desired performance. Any deviation from the standard is fed back into the control system in such a sense as to reduce the deviation.
A device to permit engagement or disengagement of equipment while in motion or at rest.
Computer Aided Design (CAD)
Programs used to design architectural, mechanical and electrical engineering drawings. CAD is the standard for documenting custom automated machine design.
Computer Aided Manufacturing (CAM)
Programs used to control manufacturing equipment.
Computer Numerical Control (CNC)
Allows the control of motion in an accurate and programmable manner through use of a dedicated computer within a numerical control unit, with a capability of local data input such that machine tools are freed from the need for "hard-wired" controllers.
Coaxial cable
A physical network medium that offers large bandwidth and the ability to support high data rates with immunity to electrical interference and a low incidence of errors.
Coefficient of Friction
A numerical expression of the ratio between the force of contact existing between two surfaces and the resistant force tending to oppose the motion of one with respect to the other. The coefficient of friction is used in determining the power necessary to drive a machine; to determine the slope angles used in hoppers, bins, chutes, and bunkers; or to determine the maximum angle of inclination for a conveyor.
Color Code
The ANSI established color code for thermocouple wires in the negative lead is always red. Color Code for base metal thermocouples is yellow for Type K, black for Type J, purple for Type E and blue for Type T.
Sequential excitation of motor windings to maintain the relative phase angle between the rotor and stator magnetic fields, within specified limits, to control motor output. In brush dc motors, this function is accomplished by a mechanical commutator and carbon brushes; in brushless motors, it's done electronically using rotor position feedback.
The ability for two devices to communicate together of software to run on a particular hardware platform.
Component orienting
A process used to bring components on an automated assembly line into their needed orientation, based on a specific component characteristic.
Concept design
Developing an initial equipment design concept, intended to accomplish specific goals, in a particular environment, satisfying a set of predetermined requirements. This concept is then developped into a full equipment design.
Concurrent engineering
The restructuring of the engineering process so that the input of all concerned parties, including manufacturing, sales and even customers, are heard from during a project's conception. A product and process design methodology that includes simultaneous participation by engineering, operations, accounting, planning, customers, vendors and other functions. The goal is to reduce engineering design/introduction lead time and reduce or eliminate later changes and quality problems by involving cross-functional teams at the outset.
The collective opinion of a group on the discussion of an issue until all agree or everyone is willing to accept the decision.
Continual improvement
Refers to the philosophy whereby every system or process within the organization is subject to continual scrutiny and improvement. Continual improvement is the antithesis of the philosophy which says, "If it ain't broke, don't fix it." Continual improvement requires that "If it ain't broke, it can be made better."
Continuous motion assembly
In continuous motion assembly, multiple processes occur without interruption for every cycle, effectively overlapping. Both the transfer of components onto a continuous-motion assembly line and their passage along it are smooth, protecting parts and assemblies against damage. The nonstop motion reduces the acceleration required to transfer parts and components assembly is very accurate because the tooling never loses contact with the individual components. Finally continuous-motion assembly requires comparatively little maintenance and experience minimal downtime versus other assembly methods.
Contract and regulation acceptance testing
In contract acceptance testing, a system is tested against acceptance criteria as documented in a contract, before the system is accepted. In regulation acceptance testing, a system is tested to ensure it meets governmental, legal and safety standards.
Contract manufacturing
The making of subcomponents or products for one company by another company. A third party that performs one or more production operations for a manufacturer who will market the final item under their own name. They often charge on a per-piece or per-lot basis for the labor required for their services while using components or materials supplied and owned by the final item manufacturer.
Control circuit
A circuit in a piece of equipment or an electrical circuit that carries the signal determining the control action, as distinct from the power used to energize the various components.
Control enclosure
The enclosure holding the electrical controls of the equipment such as the PLC, motor drives, etc. The common types of enclosures are designated by NEMA.
See Programmable Logic Controller (PLC).

Core competencies
Skills that provide the main competitive differentiation and overall base of knowledge for an organization. They may be the result of enhanced performance in a given department, such as engineering or marketing, or cross- functional such as the ability of a company to efficiently assemble the multiple skill sets needed to bid and complete large projects. Systems and departments that do not form a core competency are often candidates for outsourcing (ex.- a firm with exceptional semiconductor design engineering skills that chooses to outsource all production to a fabrication facility).
The number of time intervals counted by the dual-slope A/D converter and displayed as the reading of the panel meter, before addition of the decimal point.
A process capability index which is a statistical measure of process capability, or the ability of a process to produce output within specification limits.The concept of process capability only holds meaning for processes that are in a state of statistical control. Process capability indices measure how much "natural variation" a process experiences relative to its specification limits.
A process capability index which estimates what the process is capable of producing if the process target is centered between the specification limits. The recommended minimum process capability for two-sided specifications is 1.33 for an existing process and 1.50 for a new process.
