A Day on the Production Line: The Sensors That Keep Quality High
SPECIALIZED MANUFACTURING SENSORS Follow one batch of product through a factory and you meet a different sensor at almost every step. Each one removes a problem before it becomes a rejection.

Two sheets would crack the tool. It does this with ultrasound or an inductive method that notices extra thickness. 9:00 a.m. Machining Tool-breakage and tool-wear sensors watch spindle current, vibration or force. A worn tool leaves a poor surface. A broken tool ruins the part and can damage the machine. Changing tools by measured wear, not by the clock, saves both tools and scrap. 11:00 a.m. Welding A...
