Abstract
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.

An apparatus for predicting a characteristic of an attribute of a workpiece, the attribute having been produced as a result of a stochastic machining process, the apparatus comprising:
- at least one sensor that senses a characteristic of at least one parameter associated with the stochastic machining process and provides at least one measurement signal indicative thereof;
- and
- signal processor means, responsive to the at least one measurement signal, having a model indicative of a correspondence between the characteristic of the at least one parameter associated with the stochastic machining process and the characteristic of the resulting product attribute, and using said model to generate a signal indicative of the characteristic of the attribute of the workpiece to predict the characteristic of the attribute.
A method for predicting a characteristic of an attribute of a workpiece, the attribute having been produced as a result of a stochastic machining process, the method comprising the steps of:
- sensing a characteristic of at least one parameter associated with the stochastic machining process and providing at least one measurement signal indicative thereof;
- and
- generating, in response to the at least one measurement signal, a predicted signal indicative of the characteristic of the attribute of the workpiece, said predicted signal being generated by a model.
