Claim of US Patent No. 9,384,569

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.
