Abstract

PURPOSE:To provide a supporting table useful for forming a protuberance profiled by penetrate profiling in a work by forming previously a recessed portion on the supporting table for the work so as to oppose to a tip of an electrode. CONSTITUTION:A supporting table 7a is fixed onto a surface table 8 for supporting a work 6 and a recessed portion 7b is formed on the upper surface portion thereof. The configuration (dimension E and F) of the recessed portion 7b is formed so as to keep a relation of a<E<=a+2g, b<F<=b+2g against the sizes a and b of the electrode 1 under a consideration of a side profiling gap g. A central part of the recessed portion 7b for the supporting table 7a is formed integrally and at the same level with the outer portion of the recessed portion 7b so that electric current can be conducted therethrough to a remained protuberance 6a of the work 6 during penetrate profiling. The recessed portion 7b is formed by an electric spark machining with an electrode having a predetermined configuration. Due to these considerations, the life of the supporting talble may be elongate remarkably compared with tables of prior arts.
