Improve OEE in Manufacturing

5 Ways to Improve OEE in Manufacturing Operations

Industries use Overall Equipment Effectiveness (OEE) as a performance indicator for evaluating efficiency and productivity. OEE is the critical metric for measuring and identifying the total percentage of productive manufacturing time, which include machine and operator performances. OEE focuses on the entire manufacturing shop floor, measuring equipment availability and production quality against machine availability.

OEE metric is a crucial tool for benchmarking progress in improving manufacturing productivity. OEE in manufacturing is a key performance indicator (KPI) that compares the manufacturing system’s ideal performance to its actual performance in terms of production. This blog will give a walkthrough on OEE calculations and how to improve the OEE for better efficiency.

How to calculate OEE in manufacturing?

Overall Equipment Effectiveness is a quantifiable method to figure out how well your equipment, people, and processes perform by measuring the three factors:

  • Availability.
  • Performance.
  • Quality.

Hence, calculate OEE by multiplying equipment availability, performance, and quality. Here is the OEE calculation mentioned below.

OEE = Availability x Performance x Quality

For example, if the availability is 90%, performance is 85%, and quality is 95%, the OEE would be calculated as follows:

OEE = 90% x 85% x 95% = 72.67%

Therefore, the overall equipment effectiveness of the production process is 72.67%.

  6. Higher ROI.

What are the 5 Ways to Improve OEE?

Improving the OEE is imperative to manufacturing efficiency. To achieve this, manufacturers should have access to accurate and real-time production data from machines. Improving the OEE helps reduce manufacturing lead/cycle times and improves performance to meet customer requirements on time. OEE improvement increases efficiency, reduces downtime, and cuts costs. Let us understand how to improve OEE in your manufacturing operations.

IIoT integration for Real-Time Data Collection

The potential uses of IoT technology within the manufacturing industry are substantial. IIoT integration gives access to machine data that is generally isolated on the factory floor, to understand equipment performance through instrumentation and analytics.

IIoT integration automates the shop floor connectivity, leads to real-time access of OEE metrics for improvement. IIoT automation provides real-time information, automates equipment monitoring, and helps plant managers to make informed decisions.

Performance Analysis

Efficiency and outputs are determined by analyzing historical data. Performance analysis facilitates real-time insight and provides the root cause analysis behind inefficiencies. With performance analysis and optimization, operators can optimize their efficiency, better understand how their machines work, and predict future Performance. This can ultimately lead to an improved OEE.

Preventive Maintenance

Preventive maintenance is approach to do maintenance through which factory assets or equipment are scheduled for service regularly to prevent unplanned breakdowns and unscheduled downtime. This approach helps improve the availability of machines, leading to Overall Equipment Effectiveness in manufacturing. Preventive or scheduled maintenance improves equipment reliability and availability and increases the factory assets’ lifespan, improving OEE.

Knowledge Management:

Enhancing machine operators knowledge about production processes and machine usage substantially improves the efficiency of OEE. Operators’ engagement drives improvement to the production activities. To avoid unplanned production stops, operators’ attention in work is essential. OEE tracking and sharing the real-time OEE results with operators at regular intervals helps them gain insight into areas that need improvement, leading to further improved OEE.

Quality Production

Quality productions are free from defects or wastage and do not require rework. Quality production helps the manufacturing process run smoothly without any interruption or delay. As a result, OEE increases when production meets the expected quality standards. Quality assurance enables the production line to run smoothly, with minimal downtime and breakdowns. It also maximizes equipment utilization and efficiency, resulting in improved OEE.
