Abstract: An automatic programming system for electrodes based on UG OPEN and ODBC was developed.A Generalized Knowledge Data(GKD)base including case sub-base,tool sub-base,process parameters sub-base and operation parameters sub-base,which can be queried,modified and maintained,was created.Aiming at electrodes with special characteristics,some special programming templates for NC milling were built.When program,the case matching was firstly applied for electrodes to be milled,manufacturing knowledge was then called from the GKD according to the real milling environment,the milling program was obtained in the end.High machining efficiency and good machining effect were achieved when the system was applied in the actual cases.

Key words: secondly develop, programming, electrode, knowledge data base, manufacturing
