Detection Tool Slant Correction for Precise Machining Positioning
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional machining devices face inaccuracies in positioning components due to slanted clamping of detection tools, leading to deviations in coordinate values, which can result in improper positioning during the machining process.
Innovation Solution
A machining device and method that determine correction values for X, Y, and Z axes by using pre-set reference points and actual length measurements of the detection tool, allowing for precise positioning by calculating X, Y, and Z correction values based on the tool's design length and actual length, thereby correcting for slant errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the detection tool is clamped by the clamp, then the positioning process can be performed, but the detection tool may be clamped in a slanted position causing coordinate value deviations
Solution Approach 1:
The patent applies preliminary action by performing a slant correction value calculation process before the main positioning process. The system calculates correction values for X, Y, and Z axes based on reference points and actual tool length measurements, then applies these corrections to compensate for slanted clamping. This preliminary correction ensures that even when the detection tool is clamped at an angle, the coordinate values used for positioning remain accurate.
2Productivity
If the detection tool is clamped in a slanted position, then the positioning process can still proceed, but the coordinate values of the measurement point will deviate
Solution Approach 1:
The patent applies parameter changes by introducing correction values that modify the coordinate parameters (X, Y, Z) obtained from slanted clamping measurements. The system calculates slant correction values based on reference point measurements and actual tool length, then applies these corrections to transform the deviated coordinate values into accurate positioning data. This allows the system to maintain productivity by processing slanted clamping data while restoring manufacturing precision through parameter correction.
3Measurement precision
If correction values are calculated using slant correction, then positioning accuracy can be maintained, but the calculation process becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the correction value calculation into distinct, manageable segments: X-axis correction calculation, Y-axis correction calculation, and Z-axis correction calculation. Each axis correction is computed independently using specific reference point measurements and tool length data. This segmented approach reduces calculation complexity by breaking down the overall correction process into separate, systematic steps that can be executed sequentially.

AI summary
A controller of a machining device includes an X correction value determiner to determine an X correction value based on an X coordinate value obtained when a detection tool clamped by a clamp is brought into contact with a predetermined X reference point, a Y correction value determiner to determine a Y correction value based on a Y coordinate value obtained when the detection tool clamped by the clamp is brought into contact with a predetermined Y reference point, an actual length determiner to determine an actual length of the detection tool clamped by the clamp, and a Z correction value determiner to determine a Z correction value based on the X correction value, the Y correction value, the actual length of the detection tool, and the design length of the detection tool.
