Engineering Contradiction Analysis
1Measurement precision
If manual measurement and data transmission methods are used for machine tool calibration, then qualified personnel can perform the calibration, but the process is time-consuming and prone to inaccuracies
Solution Approach 1:
The patent replaces manual mechanical measurement methods with an automated measurement system comprising a measuring device and a data processing device. The measuring device automatically collects measurement data from the machine tool, and the data processing device automatically processes this data to generate calibration results, eliminating manual measurement and data transmission operations.
Solution Approach 2:
The measurement system performs self-measurement and self-evaluation functions. The measuring device automatically positions itself and collects data, while the data processing device automatically analyzes the data and generates calibration protocols without requiring continuous human intervention, enabling the system to calibrate itself.
2Reliability
If manual measurement methods are used, then calibration can be performed with basic equipment, but human error cannot be completely avoided
Solution Approach 1:
The patent replaces manual measurement operations with an automated measurement system that eliminates human error. The measuring device automatically collects data and the data processing device automatically processes it, ensuring consistent and reliable results without human intervention in the measurement process.
Solution Approach 2:
The patent introduces a data processing device as an intermediary between the measuring device and the final calibration results. This intermediary automatically processes measurement data, applies evaluation criteria, and generates calibration protocols, ensuring objective and reliable results without human subjectivity.
3Productivity
If automated measuring devices are used to determine topography, then precision and speed are improved, but device complexity increases
Solution Approach 1:
The measuring device is designed as a multi-functional automated system that can perform multiple measurement tasks (position measurement, orientation measurement, topography determination) using a single integrated device, reducing the need for multiple separate measurement instruments and simplifying the overall system.
Solution Approach 2:
The patent combines the measuring device and data processing device into an integrated automated measurement system. The measuring device collects data and the data processing device processes it in a unified workflow, merging multiple functions into a single coordinated system that improves efficiency while managing complexity through integration.

AI summary
The invention relates to a method (1) for determining the topography of a machine tool comprising a machine bed, a tool holder, and a workpiece carrier. The machine bed defines a Cartesian coordinate system of the machine tool originating from a machine zero point. The tool holder is displaceable along linear guides aligned parallel to axes of the coordinate system and has at least one tool receptacle for receiving a cutting tool. The workpiece carrier is spaced apart from the tool holder in the direction of a first axis and is optionally pivotable at least almost completely about a rotational axis aligned parallel to a second axis. The workpiece carrier includes a workpiece receptacle aligned parallel to the first axis, through which a workpiece to be machined can be held.
