Implementation of control cards and supporting method in production engineering
Abstract: In the article there were presented chosen method associated with statistical control of production processes. Mainly focused on control cards and Pareto-Lorenz analysis. Showed method were implemented to analysis production process stability of hearing aids in X company (the brand name don’t give because date of production is secret). Researches were made few months after new assembly lines starts-up. Main aim of researches was defects types identification occurred in production process and determine the scale of effect. Finally received results were satisfactory, i.e. despite of occurred errors, control cards analysis showed that production process of BTE-type ( Behind-The-Ear) hearing aids was stable.
Key words: production engineering, statistical process control, Pareto-Lorenz analysis
