Multiple Spindle Probe Measurement With One Common Traverse
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current machine tools with multiple workpiece holders and spindles require repetitive traversing movements for each measuring sensor, making the measurement process time-consuming and prone to sensor damage.
Innovation Solution
The operating method involves keeping measuring sensors in a rest position until they touch the workpiece, capturing their deflection during a common traversing movement, and terminating the movement when any sensor achieves its maximum deflection, allowing simultaneous position capture for all sensors and reducing the need for repeated traversing movements.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If one measuring sensor is activated at a time with sequential traversing movements, then measurement completeness is ensured, but measurement time increases significantly
Solution Approach 1:
The patent merges multiple sequential measurement operations into a single simultaneous measurement operation. Multiple measuring sensors are activated at the same time and perform measurements on multiple workpieces during one common traversing movement, rather than activating sensors sequentially. This combining of parallel measurement activities resolves the contradiction by achieving measurement completeness across all workpieces while drastically reducing the total measurement time required.
Solution Approach 2:
The patent implements continuous useful action by having multiple measuring sensors operate simultaneously during a single traversing movement. Instead of completing one measurement cycle entirely before starting the next, the system maintains continuous measurement activity across all sensors throughout the traversing movement, eliminating idle time and ensuring that all measurements are performed in an uninterrupted, parallel manner.
2Loss of information
If repetitive traversing movements are performed for each measuring sensor, then complete measurement data is obtained, but processing time increases and sensor damage risk increases
Solution Approach 1:
The patent combines multiple repetitive traversing movements into a single common traversing movement that serves all measuring sensors simultaneously. Each sensor captures measurement data during this unified movement, eliminating the need for separate repetitive cycles for each sensor. This merging approach ensures complete measurement data is obtained while minimizing the total processing time and reducing the cumulative risk of sensor damage from repeated movements.
3Manufacturing precision
If multiple traversing movements are executed sequentially, then all workpieces are measured thoroughly, but measurement efficiency decreases
Solution Approach 1:
The patent merges multiple sequential measurement tasks into a single parallel measurement operation. All measuring sensors are activated simultaneously and execute their measurements during one common traversing movement, rather than performing measurements in sequential batches. This merging maintains measurement thoroughness for all workpieces while dramatically improving measurement efficiency by eliminating the time loss associated with sequential execution.

AI summary
A machine tool holding workpieces has measuring probes disposed on spindles. The spindles move in common relative to the workpieces until a termination criterion is reached for the common displacement movement. During the common displacement movement, a position of a measuring probe relative to a respective workpiece is detected where the measuring probe makes contact with the respective workpiece or loses contact with the respective workpiece, allowing geometric statements about the respective workpiece to be derived. The measuring probes are kept at a rest position relative to their respective spindle during the common displacement movement, as long as the respective measuring probe does not yet make contact with the respective workpiece. Following contact with the respective workpiece, a deflection from a rest position is detected. The termination criterion is satisfied as soon as the deflection of at least one of the measuring probes reaches a maximum deflection.
