Application Note: Engine Vibration Testing

A major engine manufacturer was very concerned about the inconsistent quality of their shipped engines and the issues with unwanted noise and vibration, which often affect customer satisfaction. Traditional subjective testing failed to identify defects, which were eventually discovered at vehicle assembly plants or by customers. This led to expensive warranty repairs and productivity disruptions. The manufacturer required a solution with minimal tooling and fixturing modification that would reliably improve engine quality without affecting yield. read the Application Note to learn how Sciemetric solved their problem.

Application Note: Cam Shaft Grinding Application

A major automotive manufacturer was looking for an accurate quality and process monitoring system to improve yield and reduce costly defects. They were having issues with chatter marks in a cam shaft grinding operation causing engine noise and vibration (NVH) and accelerating engine component wear. Sciemetric’s test and process monitoring system resolved the problem: it measures vibration quality control, condition-based wheel dress frequency, monitors machine health to prevent future defects and more.

Application Note | Cold Engine Testing: Mechanical Integrity and Fuel Systems Tests

Engine manufacturers require a reliable and cost-effective end-of-line test to catch any defects missed during engine assembly. Hot testing, with its long cycle times and requirements for dedicated resources and facilities for stations, is expensive. Read our Application Note to learn about Sciemetric's solution.

Application Note: Engine Assembly In-Process Testing (IPT) Using Process Signature Analysis

Why wait until end-of-line testing to find defects and root-cause when that leads to increased repair costs and lowers productivity. An engine defect can be introduced at any machining or assembly station, the sooner the defects are found the better. Sciemetric’s Engine In-process testing (IPT) solution finds and contains the defect(s) through various monitors installed along critical operations important for quality assurance, such as force, torque, leak, vibration, etc. With easy generation of yield and trend reports including full drill down, it’s fast to find to find root cause.
