Method of sampling output from machine tools and a computer program to manage machine tool data, uses collection of data over a long run to provide statistically significant data on machine failure to allow automatic maintenance management

摘要

The sampling method collects operating data on a production machine over a set operating period without consideration of events where the machine is stopped to collect a record of failures over a statistically sufficient operating interval. Data is similarly recorded for a sub-set of machine functions. Intervals in which no failures are detected are also considered.
