Scientists at Samara Polytechnic University have developed and patented a program for quality control in cable production. This was reported to TASS by the university's press service. The development was carried out by a team led by Doctor of Technical Sciences, Head of the Department of Theoretical and General Electrical Engineering, Vladimir Kozlovsky. The program is based on the Shewhart control chart: a tool for continuous monitoring of production parameters, which has long been used in the automotive industry, but is practically not used in the Russian cable industry. The program received a certificate of state registration.
Shewhart Chart for Cable Production: How the System Works
In cable production, insulation thickness, conductor resistance, and product dimensions are critical. Deviations from standard values are not always noticed in time - this leads to defects and unstable quality.
The program integrates the Shewhart chart - a graph of changes in process parameters over time - and is configured to record the characteristics of each product in dynamics. A signal is received only when the difference between the reference and real value exceeds the permissible threshold. The system ignores normal process fluctuations, which saves specialists time and eliminates false alarms.
The program operates in two modes: with real measurement data from production and with simulation data, when the system generates samples with specified characteristics and simulates hypothetical technological processes.
Statistical quality control (SPC) methods have long been the standard in the automotive industry - they are used by all major manufacturers to prevent defects. In the Russian cable industry, this approach remained unclaimed: the development of Samara Polytech closes this gap and creates a basis for the introduction of SPC at domestic cable factories.
