  • Tool wear monitoring system
    Patent number: 7010386
    Abstract: A monitoring apparatus for monitoring one or more manufacturing machines having a plurality of component tools and engaged in repetitive machining of a part is provided. An input device detects occurrence of a machine cycle. A counter stores the number of detected machine cycles as a count value. A machine speed processor estimates a temporal rate at which the machine cycles occur. A data storage device stores a maintenance schedule indicating the number of machine cycles between recommended replacements for each tool. A tools processor estimates a remaining operating time for each tool before scheduled replacement. A machine viability processor estimates a remaining operating time for the machine before schedule replacement of each of the component tools. A display device displays the operating time for the machine before scheduled replacement of each of the component tools.
