Auto Chassis International uses a custom-built tester to finely measure heat distortion on brake discs. The process is made complex by the fact that the discs rotate at high speed while requiring a measurement accuracy of 0.01 mm. KEYENCE´s LK-G CCD laser displacement sensor enables stable detection despite the glowing-hot reflective metal.
Piston rings at PSA are inspected using an automated system. Since being fitted with KEYENCE laser displacement sensors a few years ago, the system makes accurate and detailed on-line measurements.
Tata Steel Europe (whose former name was Corus) is the second largest steel producer in Europe. The parent company, Tata Steel is one of the top ten steel producers in the world. The total capacity of crude steel Group, which employs about 80,000 people on four continents, is over 28 million tons. Tata Steel Rail Division France has 508 people for a production of 456,000 tons of rails and sleepers in 2009. This division has over 150 years of experience in the rail. The products are designed for high-speed lines, conventional networks, heavily loaded routes, metro and urban tramways.
The Problem: Gauging was performed using hand gauges, contact-type gauges, or some other less accurate indirect methods. Having no standard developed practice, workers at the plant were not taking reliable measurements.
The Problem: It was determined that there were two major problems with the current method of measurement.
- First, the measurements being done by hand were very inconsistent. The material being measured was not rigid, and thus the measurements varied as the amount of force applied to the micrometer by the operators changed.
- Second, the process problems that caused the thickness variation occurred very quickly, and the current “spot checking” method uncovered the problem often times too late. Thousands of dollars worth of “out of spec” material had been produced, only to be scrapped.
The Problem: The customer could not stop the line due to the sintering process or the time needed to cure in the oven. Due to the time interval in between the measurements, sometimes good product had to be thrown out along with the bad, costing production time and money. Calipers could potentially damage the product and the readings were inconsistent from shift to shift.
