ABSTRACT:
Apparatus and methods are disclosed for use in monitoring the operation of an automated machine tool which has at least one linear slide axis. Motion along the various machine axes is detected and used to provide an output signal for synchronizing the comparison of real time monitored parameters with previously stored data which varies depending upon the operational stage of the part cycle in which the machine tool is operating. In one embodiment, a plurality of sections are stored in a memory. Each section contains limit values associated with normal characteristics of parameters such as power, vibration, acoustical emission and the like which occur during a given operational stage. A preselected detected change in motion along any of the slide axes initiates the generation of a new section of limit values to be used during the comparison. Provision is also made for inhibiting the comparison when the motion information indicates that the machine is not presently removing metal from the workpiece.
