Cutting Edge Path Correction for Precision Under Tool Wear
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Machining accuracy is compromised due to wear of the cutting edge, requiring frequent tool changes and disrupting continuous operation of machining processes.
Innovation Solution
A method that corrects the track of a cutting edge by measuring and calculating errors in the machined rotation symmetry plane, allowing for real-time adjustment of the cutting edge's path to maintain precision without stopping the machine, using a computer-readable program to implement this correction.

Engineering Contradiction Analysis
1Productivity
If the cutting edge is used continuously for machining, then productivity is improved, but machining precision deteriorates due to cutting edge wear
Solution Approach 1:
The system dynamically adjusts the track parameters of the cutting edge based on measured machining errors. By changing the positional parameters of the cutting edge trajectory according to actual wear conditions, the system maintains machining precision while continuing to use the worn cutting edge, thereby resolving the contradiction between continuous operation and precision maintenance.
Solution Approach 2:
The system implements a closed-loop feedback mechanism where machining errors are measured during the process, and the cutting edge track is corrected based on these measurements. This feedback loop allows the system to compensate for cutting edge wear in real-time, maintaining precision throughout continuous operation without requiring tool changes.
2Manufacturing precision
If the cutting edge track is corrected based on measured errors, then machining precision is maintained, but system complexity increases
Solution Approach 1:
The system replaces complex mechanical adjustment mechanisms with computational methods. Instead of using intricate mechanical devices to physically adjust the cutting edge position, the system uses computer-based calculations to determine correction amounts and applies these through software control, thereby maintaining precision while reducing mechanical complexity.
Solution Approach 2:
The system creates a digital model or representation of the cutting edge track and its errors, allowing corrections to be calculated and applied virtually before actual machining. This copying approach enables precise error compensation through data processing rather than complex physical adjustment mechanisms.

AI summary
A method of correcting a track of a cutting edge is provided. With movement of the cutting edge, a point on the cutting edge in contact with the rotation symmetry plane is moved along the cutting edge from a first end portion of the cutting edge to a second end portion of the cutting edge opposite to the first end portion. The correction method includes measuring, by a measurement unit, a shape of the cut and machined rotation symmetry plane, calculating, by an operation unit, an error of the measured shape of the rotation symmetry plane from a target shape of the rotation symmetry plane in a direction of the axial line of rotation, and correcting, by the operation unit, a component in the direction of the axial line of rotation of a track of a point of cutting based on the error.
