Process variation monitoring is a non-intrusive technology that can greatly reduce scrap costs, improve operational efficiency of equipment, and help to ensure only good parts are supplied to the customer.

This in-process monitoring involves capturing the energy pulse of a machine (through a sensor), and determining the health of the manufacturing process based on consistency and repeatability. Capable processes will generate a repeatable energy profile, while incapable processes will have energy profiles with excessive variation.


Typical changes that lead to defective parts and/or machine damage:

• Raw material – hardness, thickness, cleanliness
• Presentation of material – alignment, orientation
• Machine – adjustment, fitting, tool wear, maintenance
• Machine capability – ability to deliver a repeatable process
• Lubrication
• Environment – temperature, humidity

Catching process variations and faults at the source and making the appropriate corrections before additional value is added, is the innovative solution at the core of OES Technologies.
