ABSTRACT:
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 consisting of the upper table or the lower table includes: a machining information determining means for determining bending sequences, tools, tool layouts, and work positions, based on product information; a tool management database for accumulating numbers of uses of each tool that actually bent the work along with operation of the ram, based on the determined work positions, tools and tool layouts; a number of uses of tool detecting means for detecting number of uses of each mounted tool, referring to the tool management database; and a displaying means for displaying number of uses of 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.
