{"id":"condition-based-maintenance","model_id":"PHMC","name":"NIST Prognostics, Health Management, and Control (PHMC)","summary":"The Prognostics, Health Management, and Control (PHMC) project is a NIST research effort that delivers methods, protocols, and tools for sensing, diagnostics, prognostics, and control in manufacturing. It targets vendor-neutral, plug-and-play approaches so manufacturers can use equipment and process data to support maintenance and control decisions at factory floor level. The work is split into three research thrusts: machine tool linear axes diagnostics and prognostics, manufacturing process and equipment monitoring, and health and control management for robot systems.","study_notes":["Scope covers ISA 95 manufacturing levels 0 (production process) through 3 (manufacturing operations management).","Three research thrusts: machine tool linear axes diagnostics and prognostics; manufacturing process and equipment monitoring; health and control management for robot systems.","Test beds sit at three levels: component-level (linear axis test bed), work-cell-level (robot systems test bed), and systems-level (networked machine tools and sensors in an active manufacturing facility).","Each thrust develops reference datasets, use cases, and test scenarios for public use.","Initial standards work focuses on extending MTConnect across manufacturing equipment and systems.","The robot systems thrust initially monitors degradation of tool center position accuracy of the robot arm and feeds this into work-cell control and maintenance strategies.","The project states that no open standards exist for sensing, PHM, and control from component to enterprise level; existing proprietary solutions are vendor-specific.","Project created March 12, 2014 and updated March 26, 2025."],"safety_notes":[],"sources":[{"url":"https://www.nist.gov/programs-projects/prognostics-health-management-and-control-phmc","title":"Prognostics, Health Management, and Control (PHMC)","accessed":"2026-10-25"}],"verification":{"status":"source_checked","checked_at":"2026-10-25","values":2,"method":"llm_source_check"},"updated_at":"2026-10-25","type":"operational","spec":{"kind":"methodology","origin":"NIST","related":[]},"url":"https://machineschema.com/operational/condition-based-maintenance","license":"https://creativecommons.org/licenses/by/4.0/"}
