Research And Development Of CAPP System For Mould Electrode

EDM is an important ways of mould machining. Currently , electrode processing mainly dependent on human experience,and it cause electrode low efficiency. Mould electrode CAPP system is developed based on the group technology,it take structural similarity characteristics of mould electrode,processing similarity,mold electrode practical production situation of Haier company into consideration .This article mainly includes the following conclusions:(1) Electrode classification and coding system. Based on the mould code, workpiece code number, electrode materials code, electrode type code, processing type code and flow line code attribute, establishes the electrode classification and coding system .The system include 14 codes , it convenient for description of electrode features and the inquiring .(2) The Mould electrode CAPP system has been developed based on VB and SQL Server. It includs electrode tool database,electrode process database,electrode process database and so on .It can realize inquiring of similar techniques procedure,the modifing of electrodes process templates,getting electrode tool and processing templates .It avoids the impact of skills level to ectrode programming quality .(3) The secondary development of PowerMILL based on VB and macro. It realizes the integration between PowerMILL and electrode CAPP .It can send parameters of the electrode procedure into PowerMILL,and realize automatic creating of blank,automatic positioning , NC program electrode and processing procedures of automatic or semi-automatic generation and so on .It improve the ability of the data batch processing and efficiency of electrode programming .
