AN XY LASER METER OF DIAMETER «LDM-18»
(pp. 25-29)

Abstract. Cable products are characterized by a variety of geometrical and electrical parameters usually related to each other. The outer diameter and ovality are the most important geometrical parameters for wires, insulated conductors and circular cross-section cables. Measuring the diameter of extended circular products in a divergent light flux has a number of advantages over other optical methods. In particular, the absence of a mirror and lens optics as well as portable optical units greatly simplifies the optical scheme and design of the measuring trans-ducer. Due to a robust construction and relative simplicity of design and alignment, the development and manufacturing of the XY device for measuring diameter on the basis of the diffraction method is promising for cable industry. The paper focuses on the diffraction method to measure the outer diameter of the circular extended objects in a divergent laser beam. The method enables to improve the resolution of optical transducers for the devices used for in-process control of cylindrical extended objects such as cables, wires, cords, etc. up to units of micrometers. Some issues on the technical implementation of the design and hardware-software of the device for measuring diameter “LDM-18” on the basis of the diffraction method are considered. The paper presents the technical and metrological characteristics of the measuring device designed and evaluated in real manufacturing. The obtained results can be used to develop and manufacture high-precision non-contact optical devices for in-process control of the outer diameter of cables, pipes, etc. independently and as a part of the automatic control of the manufacturing process. Application of the results and techniques presented in the paper will allow the quality improvement of the produced cables and other cylindrical extended objects and will reduce the production costs since the consumption of polymeric materials is low.

Keywords: in-process diameter measurement, diffraction, divergent beam.
