Glossary of manufacturing intelligence terms
Short, precise definitions of the terms used across quality, process control, OEE, tooling, integrations and traceability.
- APC (Automatic Process Control)
- Closed-loop control in which measured results are used to adjust a process automatically within authorised limits. Learn more
- Availability
- The OEE factor describing how much of the planned production time a machine actually runs: run time divided by planned production time. Learn more
- CIM (Control Instructions Manager)
- A system for managing revision-controlled drawings, characteristics, inspection plans and operator instructions.
- CMM (coordinate measuring machine)
- A device that measures the geometry of a part by probing points on its surface.
- Control chart
- A time-ordered chart of a process measure with a centre line and control limits, used to tell normal variation from real change. Learn more
- Cp
- Process potential: the specification width divided by six standard deviations of short-term variation. It ignores how well the process is centred. Learn more
- Cpk
- Process capability index that also accounts for centring: the distance from the mean to the nearest specification limit divided by three standard deviations of short-term variation. Learn more
- Drift
- A gradual, systematic movement of a process mean over time, for example caused by tool wear or thermal change. Learn more
- Edge (Qynetic Edge)
- A service that runs inside the factory network, close to equipment, to connect to machines, buffer data and execute deterministic control locally.
- EDHR (Electronic Device History Record)
- The electronic record showing that a device was manufactured according to its specifications, including instructions, revisions and inspection results. Learn more
- Factory Memory
- Structured manufacturing knowledge linking article, machine, program, tool, process, measurement and result, with provenance.
- Guardian
- A deterministic policy check that evaluates a proposed adjustment against authorised limits and interlocks, and denies by default. Learn more
- Individuals and moving range (I-MR) chart
- A control chart for single measurements, where limits are derived from the average moving range between consecutive values. Learn more
- Mean shift
- A sudden change in the process mean, for example after a tool change, material change or setup. Learn more
- MES (Manufacturing Execution System)
- Software that manages and records production execution on the shop floor.
- Metrology
- The science and practice of measurement, including the equipment and methods used to inspect manufactured parts.
- MQTT
- A lightweight publish/subscribe messaging protocol widely used to move machine and sensor data. Learn more
- MTConnect
- An open, royalty-free standard for reading data from manufacturing equipment in a common vocabulary. Learn more
- OEE (Overall Equipment Effectiveness)
- A measure of manufacturing productivity: availability × performance × quality. Learn more
- OPC UA
- A platform-independent industrial communication standard (IEC 62541) with a rich information model and built-in security. Learn more
- Pp and Ppk
- Performance indices calculated like Cp and Cpk but with overall variation, so they include drift and shifts. Learn more
- Provenance
- The recorded origin of a piece of data: where it came from, when it was generated and received, and whether it was transformed.
- Remaining useful life (RUL)
- An estimate of how much longer a component such as a cutting tool can be used before it should be replaced. Learn more
- SPC (Statistical Process Control)
- The use of statistical methods, mainly control charts, to monitor and control a process. Learn more
- Store-and-forward
- Buffering data locally during a connectivity outage and sending it, in order, when the connection returns.
- Tenant
- One customer organisation on a shared platform, whose data is isolated from every other tenant.
- Tool offset
- A correction value applied to a tool position or dimension in the machine control to compensate for wear or setup differences.
- Traceability
- The ability to trace a product's history — what, when, where, by which instruction and revision — through its records. Learn more
