| Summary: | The article discusses the content of the methodology
for assessing the technological state of the machine tool
system based on the method of planning experiments
for cutting pre-designed and manufactured for special
precision characteristics of automotive components of
product samples. Using the example of an internal landing
hole, the finding of diagnostic components of a special
characteristic that are the result of the action of preknown technological factors is considered. Their finding
is designed for the use of both shop and coordinate
measuring instruments. The obtained regression models of
diagnostic components make it possible at various stages
of the APQP process to determine the intervals of the
cutting process parameters that provide a predetermined
margin of accuracy of a special characteristic, or to
conclude that the accuracy of the machine system is inadequate. The application of the methodology together
with statistical methods of quality management allows
to ensure the maximum achievable level of stability of
special characteristics in cutting operations, starting with
the release of the first serial samples of products. The
methodology can be used when selecting and evaluating
the technological accuracy of newly purchased equipment
in the APQP process of preparing the production of a new
automotive component, acceptance of existing equipment
after modernization or repair, as well as the audit of the
technological process by the auditors of the supplier. |
