Abstract: A magnetostrictive wire waveguide type position measuring system wherein the wire waveguide is mounted within a small diameter brass tube which, in turn, is mounted by way of resilient suspension components within a rigid outer tube affixed to a position reference frame. The suspension components isolate the waveguide from relatively high frequency shock inputs characteristic of rough environment applications. The position signal is derived from output signal quantities generated by the propagation times of sonic disturbances from a first reference magnet held in a fixed position relative to the outer housing and a second user magnet which moves relative to the outer housing with the element or quantity being monitored. To compensate for longitudinal movement of the waveguide within the floating suspension system, a computer calculates a variable time delay related to the difference between a constant time quantity and the propagation time of the reference magnet impulse and adds this time delay to the user magnet propagation time. The waveguide terminal ends are gradually reconfigured from round to flat, rectangular sections and sandwiched between acoustic dampening pads to reduce or eliminate sonic reflections. A flexible film piezoelectric pickup is disclosed.

Abstract: A method for calibrating an orthogonal sensor suite includes the steps of imparting on the sensor suite a series of known accelerations at orientations known relative to each other, while recording readings from the sensors from each acceleration at each orientation. This data is used to create a transformation matrix which removes offsets from each sensor and removes any cross-coupling of the sensors.

Abstract: The present invention is a combined magnetostrictive linear displacement detector and plural location temperature detector. The combined apparatus produces a composite signal for transmission on a 2 wire transmission line. The resistances of the temperature sensitive resistors as well as two reference resistors are measured in a predetermined sequence. The linear displacement is measured by the length of time required for a torsional strain to travel along the magnetostrictive wire to the position of the magnet. A pulse generator generates a predetermined number of pulses for each resistance measurement having pulse period corresponding to the measured resistance, with the minimum such pulse period preferably being greater than twice the maximum time required for a torsional strain to propagate the length of the magnetostrictive wire. An electrical signal is supplied to the transmission line when either said pulse generator generates a pulse or the induced electrical signal is detected. The time between the pairs of pulses indicates the linear displacement fixed by the magnet. The time between pulse pairs is a measure of one of the resistances. The combined apparatus of the present invention also periodically degausses the magneteostrictive wire at a time when no displacement measurement is taking place.

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.

Abstract: A worn tool detector system for analyzing input signals from a sensor were the signal is in the form of an analog waveform exhibiting periodic impulses exceeding the average amplitude thereof as the tool wears. A microprocessor controlled variable gain amplification network is utilized to normalize the average waveform amplitude to a fixed level. During machine operation, impulses are detected by comparing the sensor waveform to a programmable selected ratio of the normalized level. When a given number of successive impulses are received the microprocessor generates a warning signal which may be used to retract the tool. An adaptive mode is disclosed wherein the sensor waveform throughout the course of the machining operation is repetitively normalized to adjust for different sensor waveform amplitudes.
