Abstract:
A CAD/CAM device for an electric discharge machine comprising: a machining tank for storing a machining solution; a positioning device for relatively moving a workpiece, which is fixed to a surface plate arranged in the machining tank, and an electrode; a machining electric power supply means for supplying machining electric power to between the workpiece and the electrode; and a machining tank drive means for changing a level of a surface of the machining solution with respect to the workpiece by driving the machining tank,the CAD/CAM device for an electric discharge machine further comprising a check means for checking whether or not a level of a predetermined position of a device to be protected from being soaked in the machining solution is lower than a safe level of a surface of the machining solution when a safe level of the surface of the machining solution, which is obtained when a predetermined safe distance is added to a level of a predetermined position of the workpiece with respect to a predetermined reference position, is compared with the level of the predetermined position of the device with respect to the predetermined reference position before conducting actual machining.
