Load monitoring apparatus

摘要

Apparatus for monitoring the performance of a machine tool comprises one or more transducers which operate continuously to measure selected dynamic characteristics of tooling during operation of a machine tool. Means are provided for transmitting signals representative of measured dynamic characteristics to a micro-processor housed within the structure of the machine tool and to provide on a visual display unit of the machine a graphical display of the measured dynamic characteristics. The same visual display unit provides a graphical display of previously derived dynamic characteristics to enable a machine operator to detect changes in measured characteristics over a predetermined period of time.
