Summary

Automatic tool changer is frequently utilized to improve tool carrying capacity of CNC machine. CNC machine that is computer numerical control machine with automatic tool changer increases the productivity time of machine tool reduces the times for changing worn tools. The uses of tools and machines and throughput of each part type are three significant performance measures that must be managed for efficient production. Therefore it is essential to calculate effective number of tool needed for machining. Tool management contains tool magazine and automatic tool changer, Tool storage and support system, tool handling system, tool fault detection system. The success of tool management depends mainly on several tool storage policies.
