“…Calculation of control limits -the control limits represent a narrowing of the tolerance field. They serve for preventive control of the process-if the monitored feature exceeds this limit (the feature is still inside the tolerance field), the process control is necessary so that the values of the monitored feature return to the centre of the tolerance field [19][20][21]. To determine the control limits, it is necessary to know the calculated value of process capability index Cp, the width of the tolerance field T, the tolerance centre ST and the coefficient K2 (this is given by ČSN ISO 8258).…”

This paper is devoted to the use of statistical methods to ensure the highest quality processes. Specifically, it deals with creating an application in MS Excel which evaluates standard statistical parameters and if the required process capability indices are complied with, then it is possible to proceed to SPC (statistical process control). The application was created in MS Excel using the Visual Basic for Application programming language. In addition to the required calculations, the application also generates forms with all important data. This application was designed to reduce reject rate and improve the production process in a contracting company.

The article reveals the main provisions of technical diagnostics of gear hobbing machine system with CNC on the diagnostic parameters of the profile of the sides of the teeth. The scheme of embedding diagnostic processes in the cycle of improving the quality of manufacture of gears. The developed scheme is universal and applicable to any gear processing operations. It consists of several successive steps – the evaluation of indicators relative to the limit values, the identification of the technological structure of the profile errors and the identification and analysis of diagnostic deviations of the profile of the lateral surface of the teeth, indicating. Each step of the improvement cycle is necessary to determine the negative factors of the process leading to a deterioration in the quality of manufacture of gears. Application of technical diagnostics profile diagnostic indicators allows to detect deviations of the technical condition of machine components, adjustment or tuning machinery. Diagnostic indicators are identified for the most significant technological components of non-conforming errors of the profile of the sides of the teeth of the gear wheel. The advantage of this quality improvement scheme is that it is more efficient than traditional methods of statistical quality management.
