Machining command improving system and machining command improving method

A machining command improving system in an integrated system in which a CNC machine tool for machining of a machining target into a predetermined machining geometry on the basis of a machining command, wherein the CNC machine tool and a shared database are connected to each other, the machining command improving system being a system for improving the machining command, wherein the machining command improving system comprising:

• a machining state recording unit that is configured to
• start collection of information indicating a state of execution of the machining command on the basis of a first notification of a start of execution of machining by the machining command each time the CNC machine tool executes the machining command, the first notification being acquired from the CNC machine tool, the collection of the information indicating the state being performed for each machining step of a plurality of machining steps, and
• generate machining technique information on the basis of the information indicating the state collected in each machining step of the plurality of machining steps, contents of the machining command executed in each machining step of the plurality of machining steps by the CNC machine tool, and tool information about a tool used in each machining step of the plurality of machining steps, and
• register and accumulate the generated machining technique information in the shared database;
• and
• a machining method improving unit, the machining method improving unit configured to
• identify a machining geometry and machining request information included in an acquired machining command on the basis of a second notification of the acquired machining command for machining to be performed next, the second notification being acquired from the CNC machine tool,
• acquire all pieces of the machining technique information, each including a machining geometry at least partially the same as the identified machining geometry and conforming at least partially to the identified machining request information,
• determine the machining technique information from the acquired pieces of machining technique information achieving the highest satisfaction of a request in the machining request information conforming to the machining command,
• improve the machining command by replacing the contents of the machining command with contents of the machining technique information achieving the highest satisfaction of the request in the machining request information, and
• notify the improved machining command to the CNC machine tool to thereby cause the CNC machine tool to execute the machining on the basis of the improved machining command,
• wherein the machining request information includes one or more of an aim of machining, a material of a machining target, CAM tolerance, surface roughness, geometrical tolerance, and dimensional tolerance,
• wherein the machining state recording unit is configured to generate and store the machining technique information each time the machining command is executed by the CNC machine tool,
• wherein pieces of the information indicating the state are collected for each machining step of the plurality of machining steps of the machining command, and
• wherein the information indicating the state includes one or more of a servo information, a data information from various sensors, and a captured image showing a machining state.
