Claim Text:
1. An apparatus, comprising: a waveform display device including a data management function, which is connected to a numerical controller configured to drivingly control a machine tool, configured to acquire drive-axis data representative of an operation and/or state of the machine tool obtained from the numerical controller, and display a waveform of the drive-axis data, the waveform display device being configured to: acquire the drive-axis data from the numerical controller; acquire a parameter of the numerical controller from the numerical controller; and manage the drive-axis data and the parameter in association with each other based on a time at which the drive axis data is acquired and a time at which the parameter is acquired, wherein the time at which the drive-axis data is acquired and the time at which the parameter is acquired are generated by a timer of the waveform display device; adjust the time at which the drive-axis data is acquired and the time at which the parameter is changed based on a time lag between the timer of the numerical controller and the timer waveform display device; and acquire time data from the timer of the numerical controller and time data from the timer of the waveform display device simultaneously.
