The present invention includes at least one sensor that senses the characteristic of one or more parameters associated with a stochastic machining process and provides one or more measurement signals indicative thereof, and further includes a signal processor having a model indicative of a correspondence between the characteristic of the parameters associated with the stochastic machining process and the characteristic of the resulting product attribute, and uses the model to generate a signal indicative of the predicted characteristic of the attribute of the product.

Method and apparatus for predicting a characteristic of a product attribute formed by a machining process using a model of the process

An automated method and apparatus for electrode discharge machining wherein method includes moving the tool holder to the electrode loader, automatically mounting an electrode into the tool holder and then testing the electrode for conformance to geometric and dimension tolerances and testing the electrode for proper alignment in the tool holder and thus proper alignment relative to the workpiece just prior to moving the tool holder to the workpiece area for machining. The apparatus includes a moveable servomechanism with a tool holder, an electrode magazine, and a sensor module for testing an electrode mounted in the tool holder. The sensor module has a recess configuration of conductive material complimentary to the electrode such that the electrode will make contact with the conductive material when inserted into the sensor module if the electrode is out of tolerance or misaligned in the tool holder.

Method and apparatus for testing electrodes in an EDM process

A method of inspection for a fluid to determine its suitability for use as a dielectric medium in an EDM system and a method of maintenance for an EDM system having a dielectric fluid include generating an indication of the density of a sample of the fluid, providing at least one reference associated with at least one measure of suitability of the fluid, and comparing the indication to the at least one reference to determine, in the case of the method of inspection, the suitability of the fluid for use in the system, and in the case of the method of maintenance, whether to replace the fluid in the EDM system.
