How is performance measured in OEE?
The performance component of OEE measures how quickly equipment runs compared with its ideal or planned cycle rate while it is operating. It identifies speed losses caused by slow cycles, reduced feeds and speeds, brief interruptions, and micro-stops. Harmoni uses automatically collected machine cycle-time data to show actual operating performance and help teams identify where output is falling below expected production rates.
Yes. OEE is a widely used manufacturing KPI because it combines availability, performance, and quality into one measure of how effectively equipment is producing good parts during planned production time. It is most valuable when teams can also see the drivers behind the score. Harmoni provides real-time context for downtime, cycle performance, job activity, and quality losses so leaders can act on the KPI.
What are the three components of OEE?
OEE consists of availability, performance, and quality. Availability accounts for time lost to stops such as breakdowns, changeovers, and material waits. Performance measures whether equipment runs at its ideal rate while operating. Quality measures the share of produced parts that meet requirements without rework or scrap. Multiplying these three factors produces the OEE score for the selected machine, job, shift, or period.
How does OEE software collect machine data?
OEE software connects to supported CNC controls and manufacturing equipment to capture machine status, cycle-time data, utilization, and stop conditions automatically. Harmoni supports major controls including Mazak, Haas, Fanuc, Heidenhain, Siemens, DMG MORI, Makino, and Fadal. It can then combine machine information with operator, job, quality, and ERP data to provide a complete view of production performance.
Can OEE software identify downtime reasons?
Yes. Harmoni helps teams classify downtime into actionable causes, including changeovers, equipment breakdowns, micro-stops, material waits, operator waits, and quality holds. Instead of seeing only total lost time, supervisors and continuous-improvement teams can identify recurring patterns by machine, job, shift, or reason. This makes it easier to assign ownership and focus improvement work on the losses with the greatest capacity impact.
Does Harmoni integrate OEE data with ERP systems?
Harmoni integrates shop-floor data with major manufacturing ERP systems, including Epicor, Infor and Infor Visual, ECI JobBoss and JobBoss2, ABAS, and ODOO. The platform can push labor records, machine production time, scrap, and quality data into the ERP automatically. That connection reduces manual reconciliation while supporting more accurate job costing, capacity reporting, planning, and financial reporting.
Can older CNC machines be included in OEE monitoring?
Yes. Harmoni supports a broad range of CNC controls, including legacy equipment, through MTConnect where available and adapter layers for older controls. The platform is designed to connect to existing machines rather than require replacement. During evaluation, the team can review the control type, connectivity, and available signals to determine the most practical approach for bringing each workcenter into monitoring.
Who benefits most from real-time OEE monitoring?
Real-time OEE monitoring benefits plant managers, operations leaders, supervisors, manufacturing engineers, continuous-improvement teams, schedulers, quality managers, and finance leaders. Operators gain clearer machine-side context, while leaders gain visibility into capacity, downtime, labor, scrap, and job performance. It is particularly useful for CNC machining and other complex manufacturing environments where delayed reporting can conceal losses until production is complete.
