Machining-information management device and tool-path generation device

A machining information management device for managing machining information of a machine tool using a machining program as a basis for making a tool and a workpiece move relatively for machining, the device comprising a computer readable non-transitory medium storing therein instructions comprising:

• receiving the machining program, for performing predetermined machining of the workpiece, tool information and coordinate information;
• analyzing the machining program so as to judge for every command in the machining program whether or not it is a tool change command or a coordinate system selection command, and extracting the tool change command or the coordinate select command if it is a tool change command or a coordinate system selection command;
• acquiring from the received tool information, tool information relating to a tool designated by the tool change command, and acquiring, from the received coordinate information, coordinate information relating to a coordinate system designated by the coordinate system selection command;
• and
• generating general machining information including the machining program, the acquired tool information, and the acquired coordinate information.
