ABSTRACT:
An automatic TW (traveling-wire) electroerosion machining system for machining a plurality of workpieces of different types required to acquire different contours includes a TW machine having a wire setting unit and located adjacent a predetermined path. A work dispensing unit successively dispenses the different workpieces onto the path from a store thereof located adjacent the path. This unit and a work handling and transfer unit operate under control commands from an NC unit and, in conjunction with the TW machine with the wire setting unit to carry out a plurality of work processing operations sequentially. In each operation, each individual workpiece selected from the store is transferred as it is carried on a pallet for loading onto and unloading from the TW machine. The electrode setting unit on the machine acts both to form a start hole and thread a wire-type electrode through the formed hole in the workpiece. The unloaded workpieces are transferred to an inspection stage for classification into acceptable and unacceptable products.
