Abstract:
Besides dimensional and shape accuracy, eliability and life cycle of components produced in different wayshighly depend on the quality of the processed surface. There are some automotive industrial parts where it is important to have appropriate surfaces. In these cases it is necessary to examine the measurement process for its suitability, for its capability.
The calculation methods of capability of measurement processes in automotive industry differ from each other. There are three main calculation methods: MSA, VDA 5 and the international standard, ISO 22514-7. During this research our aim was to compare the capability calculation methods in a case-study. Ten automotive parts are chosen to examine the behavior of the manufacturing process and to measure the required characteristics of the measurement process being evaluated. The measurement uncertainty of the measuring process is calculated according to the VDA 5 and ISO 22514-7, and MSA guidelines.
In this study the conformance of a measurement process in an automotive manufacturing process is determined, and it is shown what are the similarities and the differences between the used methods.
