A bending apparatus for bending a work using a punch mounted onto an upper table and a die mounted onto a lower table by operation of a ram including the upper table or the lower table, the apparatus comprising: a machining information determining device that determines bending sequences based on product information, determines tools and tool layouts for each of the bending sequences, and determines work positions; a tool management database that, based upon operations of the ram, determined work positions, tools, and tool layouts, determines and accumulates a number of uses of each tool, mounted on the ram, that actually bends the work and each tool, mounted on the ram, that does not bend the work; a tool usage detector that detects the number of uses of each tool mounted on the ram; and a display that displays a number of uses of a relevant predetermined tool, when the detected number of uses of each tool becomes equal or approximate to a durable number of uses, or when a display command signal from a worker side is input.
