The application of Laser Doppler Velocimetry for the non-contact speed/length measurement and sequential printing of wire and cable products to decrease costs and improve productivity

摘要

One study finding was that phosphate on a steel surface during heat treatments can lead to phosphorous penetration and ultimately weaken the steel. Measurement of length and speed in wire and cable applications is very important. Each spool provided must have the correct length of material. A spool with less than the specified amount of material could result in the spool being sent back to the manufacturer. To guard against this, manufacturers commonly put extra material on the spool. Unfortunately, this extra material is just given away. Giving away extra material is giving away extra money. The amount of material given away is dependent on the accuracy of the length measurement device used. Traditionally, contact encoders are used.
