Solution Overview
Problem
Coordinate measuring machines face challenges in determining and adapting operating parameters accurately across different configurations, especially when components are added, removed, or changed during measurement operations, leading to complexities in calculating valid maximum speeds, accelerations, and other operating parameters.

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If operating parameters are determined for each component individually, then the determination becomes more accurate and reliable, but the complexity of the control system increases
Solution Approach 1:
The control system segments the determination of operating parameters by assigning specific parameter values and regulations to individual components. Each component (measuring head, rotary table, counter holder, etc.) has its own associated operating parameters stored in the control device. This segmentation allows accurate determination while managing complexity through structured organization.
Solution Approach 2:
The control device stores operating parameters and regulations for all possible components in advance. When components are added, removed, or changed during measurement operations, the control device can immediately retrieve the appropriate parameters without complex real-time calculations, thereby maintaining reliability while reducing operational complexity.
2Measurement precision
If the control system adapts to configuration changes by recalculating operating parameters, then the measurement operation remains accurate, but the time required to determine parameters increases
Solution Approach 1:
All operating parameters and regulations are pre-stored in the control device for various components. When configuration changes occur, the control device simply retrieves the appropriate pre-stored parameters rather than recalculating them, maintaining measurement precision while minimizing parameter determination time.
Solution Approach 2:
The control device maintains copies of operating parameters for different component configurations. When a component is added, removed, or changed, the control device switches to the corresponding pre-stored parameter set, enabling rapid adaptation without time-consuming recalculation while preserving measurement accuracy.
3Reliability
If multiple regulations are applied to determine operating parameters, then the safety and accuracy of measurement operations improve, but the complexity of parameter calculation increases
Solution Approach 1:
Multiple regulations are segmented and assigned to specific components individually. Each component has its own associated regulations stored in the control device (e.g., maximum speeds, accelerations, probing forces). This segmentation allows comprehensive safety coverage while simplifying the calculation process by organizing regulations in a structured, component-specific manner.
Solution Approach 2:
The control device merges multiple component-specific regulations into a unified operating parameter determination process. When determining parameters, the control device automatically combines the regulations of all present components to establish the final safe operating limits, ensuring comprehensive safety without requiring complex manual calculations.

AI summary
The invention relates to a method for controlling an operation of a coordinate measuring device (11), wherein at least one operational parameter, for example the maximum speed, maximum acceleration, limitation zone of a displacement area or limiting value for signal recognition, is determined, said parameter being available during operation. One value of the operational parameter and/or instruction and/or information for determining the operational parameter is allocated to a plurality of components (11, 12, 13, 14, 16, 17, 18, 19) of the coordinate measuring device (11). A sequence for determining the operational parameter is provided for the majority of the components (11, 12, 13, 14, 16, 17, 18, 19). The method for determining the operational parameter in the predetermined sequence for each component (11, 12, 13, 14, 16, 17, 18, 19) is the following; it starts with the component (11) that is first in the sequence: i) if the value of the operational parameter is allocated to the component (11, 12, 13, 14, 16, 17, 18, 19), said value is adopted as a value of the operational parameter that is available for the operation, ii) if no value of the operational parameter is allocated to the components (11, 12, 13, 14, 16, 17, 18, 19), one available value of the operational parameter that was available until then still remains available, iii) if another component (12, 13, 14, 16, 17, 18, 19) is provided in the sequence, the method is carried out with said component.
