1Measurement precision
If drive-axis data and parameters are managed separately on different devices, then data management is simpler, but accurate association and comparison between data and parameters becomes difficult
Solution Approach 1:
The patent combines the management of drive-axis data and parameters into a single waveform display device. The parameter storage unit and waveform display unit are integrated in one device, allowing both data types to be managed together with consistent timing information from a single timer, enabling accurate association without the complexity of inter-device synchronization.
Solution Approach 2:
The patent introduces timing information generated by a timer as an intermediary to associate drive-axis data and parameters. By attaching timing data to both parameter storage and waveform data acquisition, the system creates a common reference framework that enables accurate matching between parameters and corresponding drive-axis data without direct complex linking mechanisms.
2Productivity
If parameters are manually associated with measured data, then flexibility in data selection is maintained, but substantial operator labor is required
Solution Approach 1:
The system performs automatic association of parameters with drive-axis data through the integrated management structure. The waveform display device automatically links parameters stored in its parameter storage unit with corresponding waveform data using timing information, eliminating the need for manual operator intervention in the data association process while maintaining operational flexibility.
Solution Approach 2:
The patent implements preliminary association of parameters with timing information during the data acquisition phase. By storing parameters with their corresponding timing data in the parameter storage unit from the outset, the system prepares the data for automatic matching later, eliminating the need for manual association operations during analysis.
3Productivity
If parameters are automatically associated with measured data, then operator labor is reduced, but correct association cannot be ensured without proper synchronization
Solution Approach 1:
The patent uses timing information as an intermediary to ensure reliable automatic association. Both parameters and drive-axis data are tagged with timing information from a common timer, creating an objective reference that enables accurate automatic matching without manual intervention, thereby ensuring both automation and reliability.
Solution Approach 2:
The system implements feedback through the display unit that shows both waveform data and corresponding parameters together. This visual feedback mechanism allows operators to verify the correctness of automatic associations, providing a check that ensures reliability while maintaining automation benefits.

AI summary
A waveform display device with a data management function acquires drive-axis data of a machine tool from a numerical controller for controlling the machine tool and acquires parameters of the numerical controller from the numerical controller. The waveform display device manages the drive-axis data and the parameters 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. These times of acquisition of the drive-axis data and the parameters are set by a timer of the waveform display device.
