A method for measuring microwire parameters

Abstract

The most common techniques for measuring microwire geometrical parameters are provided by post manufactory measurements. These techniques are incompatible within automated production of microwire. A specialized meter is usually used for core diameter measurement on casting, which allows the operator to monitor the diameter of microwire and control the casting process. Its typical accuracy is of a 5 to 10% order, within quite narrow limits. Other methods of measuring thin wires are based on scattering and diffraction effects of a laser beam. These methods are quite precise and accurate, but at the same time, exigent to environmental conditions and wire vibrations during measurement process.
