Machine Tool Parameter Correction Using Multi-Feature Feedback
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current methods for correcting tool parameters in machine tools require highly qualified personnel and are time-consuming, as they involve manual adjustments to compensate for production errors, often through a trial and error process, which can lead to overcorrection of individual measurement features or parameters.
Innovation Solution
A method that automatically records and compares measurement data from multiple features and parameters, calculates a weighted average tool correction value, and applies corrections within specified tolerance limits, allowing for fully automated tool parameter adjustments without the need for highly qualified personnel.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If manual parameter correction is performed by experienced operators, then production errors can be compensated, but highly qualified personnel are required and the process is time-consuming
Solution Approach 1:
The machine tool system automatically performs parameter correction using measured deviation data without requiring manual intervention by operators. The control unit calculates correction values and adjusts tool parameters autonomously based on measurement results, enabling the system to correct its own errors
Solution Approach 2:
The manual mechanical adjustment process by operators is replaced with an automated computational system. The control unit uses measurement data to calculate optimal correction values and automatically adjusts tool parameters, substituting human expertise with algorithmic processing
2Manufacturing precision
If trial and error approach is used to correct production errors, then parameter adjustments can be made, but the process is time-consuming and costly
Solution Approach 1:
The system measures actual workpiece dimensions, compares them with nominal values, and uses the deviation data to calculate correction values. This closed-loop feedback mechanism eliminates trial and error by directly determining the necessary parameter adjustments based on measured errors
Solution Approach 2:
The system performs parameter correction before producing defective parts by continuously monitoring measurement data and proactively adjusting tool parameters. This prevents future deviations rather than correcting them after they occur
3Manufacturing precision
If parameter values are changed to compensate for production errors, then quality can be improved, but overcorrection of individual features can occur
Solution Approach 1:
The system combines multiple measurement features and parameters into a single integrated correction calculation. By considering all measured deviations together rather than individually, the control unit calculates a balanced correction value that prevents overcorrection of any single feature while improving overall workpiece quality

AI summary
The invention relates to a method for correcting tool parameters of a machine tool for machining workpieces, in which measurement data of measurement features are recorded as actual values of at least one workpiece machined with the machine tool, in which the measurement data are compared with predetermined target values of the workpiece, in which measurement data of at least two measurement features of at least two parameters of at least one measurement feature and/or of at least one measurement feature and of at least one parameter are recorded, in which an average value for a tool correction value is calculated from these measurement data and the associated target values, with which a correction of the machine tool is carried out.
