Direct subclasses:
Definition
physical artefact or system that transforms energy or material through guided mechanical, electrical or fluid power for performing one or more processes.
Semi-Formal Definition:
if x is a machine then x is a physical artefact and x transforms energy or material through guided mechanical, electrical or fluid power in order to perform one or more processes
Adapted From
-
- ISO 12100 defines “machine” as an “assembly, fitted with or intended to be fitted with a drive system other than directly applied human or animal effort, consisting of linked parts or components, at least one of which moves” NIST.
- IEC 60050‑151 defines “machine” as “a system or device that uses energy to perform a specific task, often automatically” (Electropedia).
- NIST (Smart Manufacturing Ontology) treats a machine as an “equipment unit that executes physical transformations autonomously or semi‑autonomously using power and control systems.” (see https://oagi.atlassian.net/wiki/spaces/IOF/pages/5952208897/Characterization+of+machines+and+tools#Trait-analysis)
Primitive Class
This class is declared primitive and it does not have necessary and sufficient condiftions defined.
Primitive Rationale
Many of the core characterizations of machine captured in the trait analysis (see https://oagi.atlassian.net/wiki/spaces/IOF/pages/5952208897/Characterization+of+machines+and+tools#Trait-analysis) cannot be formally expressed, especially energy transformation, power, control, motion and mechanical structures.
