Frequently Asked Questions
Machine utilization measures how much of the total available time the machine was actually running (including setup). OEE Availability specifically measures how much of the planned production time was actually used for production (excluding planned downtime). Utilization is broader; OEE Availability is a subset.
It depends on the machine type and industry. For CNC machines: 70–85% is excellent. For injection molding: 80–90%. Too high utilization (>95%) leaves no room for maintenance and increases breakdown risk.
Idle time cost = Idle hours × Hourly machine cost. Include depreciation, utilities, lease payments, and operator cost in the hourly rate. This cost is often surprising and justifies investment in uptime improvement.
Planned downtime is scheduled and accepted: preventive maintenance, lunch breaks, planned changeovers. Unplanned downtime is unexpected: equipment failures, material shortages, quality problems. Reducing unplanned downtime gives the highest ROI.
