Production of dials for analogue electrical measuring instruments with non-linear measuring mechanism by means of laser engraving

The subject of this research is a benchmark analysis of methods for single-item production of dials for electrical measuring instruments. The research was held with the aim to improve the quality of produced dials and also to enhance efficiency of printing the information signs and labels onto the dial. The research uses mathematical tool of digital image processing and the position detection of instrument’s pointer indicator in real time. The laser engraving method is used to improve the production quality of dials. The structure of hardware and software complex is developed as well as software for operation control. Hardware and software complex for production of dials is developed and introduced into manufacturing process.
