Operation management device

An operation management device managing operation conditions of a machine tool, the operation management device comprising:

• a machining program information acquisition unit acquiring information related to machining program executed in the machine tool;
• a signaling information acquisition unit acquiring signaling information related to a signal detected during execution of the machining programs in the machine tool;
• an associated-information creation unit associating the information related to the machining program with the signaling information;
• and
• a search/display unit displaying the information related to the machining program and the signaling information, which are associated by the associated-information creation unit, in a manner such that they are associated with each other,
• wherein the associated-information creation unit is configured to
• add a first block identifier to each block among a plurality of blocks in the information related to the machining program executed in the machining tool, and
• add a second block identifier to the signal information, the second block identifier associated with the first block identifier and corresponding to a value of the signal, said value detected at a time when said each block is executed.
