<p>A method of automatically retrieving working conditions in an electric discharge machine, wherein the said method is built up on the basis of an expert system and, even by an unskilled operator, optimal working conditions in the electric discharge machine can be set. A source knowledge base (6) prepared on the basis of the knowledge and experience of an expert (5) an including data on working conditions and production rules is converted into an object knowledge base (3) by a compiler (4), and subsequently, the knowledge base (3) together with an inference engine (2) are stored in a computer-incorporating type numerical control device (10) equipped on the electric discharge machine. When the operator (1) inputs the retrieving conditions including the diameter of the wire, the material quality of the work, the plate thickness of the work, the desirable mean working speed, the surface roughness, the working accuracy and the like via a manual input data device (25) in order to perform automatic retrieving of the working conditions, the inference engine successively processes the production rules relating to the retrieving conditions while utilizing the data on the working conditions relating to the production rules, retrieves the working conditions suitable for the retrieving conditions and displays them on a display screen. <IMAGE></p> |
