Probe Calibration Value Storage for Interchangeable Measuring Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing measuring systems with probe-interchangeable machines require repeated calibration operations each time a probe is attached, which increases working time and reduces efficiency.
Innovation Solution
A measuring system that includes a control device capable of recording and processing calibration values for multiple candidate probes, allowing for pre-measurement calibration value recording and selection of the appropriate probe for a workpiece, eliminating the need for calibration during each measurement operation.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If calibration operation is performed for each probe attachment, then measurement accuracy is ensured, but working time increases and productivity decreases
Solution Approach 1:
The calibration values for multiple candidate probes are measured and recorded in advance before actual measurement operations. This preliminary calibration eliminates the need for repeated calibration when probes are exchanged during measurement tasks, thereby maintaining measurement accuracy while significantly improving working efficiency.
2Measurement precision
If calibration operation is performed for each probe attachment, then probe accuracy is verified, but time consumption increases
Solution Approach 1:
Calibration values for all candidate probes are determined and stored in advance. When a probe is attached to the measuring machine, the corresponding pre-recorded calibration value is simply retrieved from storage, eliminating the time-consuming calibration process while ensuring probe accuracy is maintained.
3Adaptability or versatility
If multiple candidate probes are prepared for different measurement tasks, then measurement versatility is improved, but probe management complexity increases
Solution Approach 1:
The measuring machine is designed to accommodate multiple candidate probes with different measurement functions. The control device includes a storage unit that universally manages calibration values for all candidate probes, allowing the system to handle various measurement tasks while simplifying probe management through centralized calibration data storage and automatic retrieval.
