Cast metal parts are created for use in making machinery. When these parts are formed, unwanted material remains in the openings of the parts. This material, called flash, must be removed. In the method of the present invention, the cast parts are placed on a platen of a trim press that has multi-part punches attached thereto that are configured to self-align with the openings in the cast part and operative to evenly remove the flash. The invention also relates to a punch that initially breaks through the flash with a stationary punch that removes a majority of the flash inside the opening of the cast part. Next, a moving or self-centering punch self-aligns to the opening in the cast part and operates to remove the remaining flash. The inventive punch may also include a mounting base for attachment of the multi-part punches to the plate or platen of the press.
