Solution Overview
Problem
Dental cutting machines often experience operational errors due to aging or other reasons, leading to products deviating from specified dimensions in machining programs.
Innovation Solution
A correction method involving inputting a machining program for a correction piece, machining the piece, measuring its dimensions, calculating a correction value, and inputting this value back into the dental cutting machine to correct operational errors.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If the dental cutting machine operates without correction, then the machining process continues without interruption, but the manufacturing precision deteriorates due to operational errors and aging
Solution Approach 1:
The system performs preliminary measurement and correction by machining a correction piece with predetermined dimensions, measuring its actual dimensions, calculating correction values, and applying these corrections before normal production machining continues. This preliminary action restores the machine's precision without requiring full recalibration or停机 for extended periods.
Solution Approach 2:
The system establishes a feedback loop where the measured dimensions of the correction piece are compared against the predetermined dimensions, correction values are calculated from these differences, and the calculated corrections are applied back to the cutting machine's control system. This closed-loop feedback mechanism continuously maintains manufacturing precision despite operational drift and aging.
2Manufacturing precision
If a correction piece is machined and measured to calculate correction values, then the manufacturing precision is restored, but the productivity decreases due to additional correction steps
Solution Approach 1:
Instead of performing comprehensive recalibration of the entire cutting machine system, the method applies partial correction by focusing only on the essential correction values derived from measuring the correction piece's critical dimensions. This partial action approach restores sufficient precision for production while minimizing the time and resources required compared to full system recalibration.
3Manufacturing precision
If complex correction procedures are implemented, then the manufacturing precision improves, but the device complexity increases
Solution Approach 1:
The cutting machine system performs its own self-diagnosis and self-correction by automatically machining a correction piece, measuring its dimensions, calculating correction values, and applying these corrections to its own control parameters. This self-service capability eliminates the need for complex external calibration equipment and manual adjustment procedures, maintaining precision while minimizing system complexity.

AI summary
A correction method for a dental cutting machine includes inputting a machining program of a correction piece to the dental cutting machine, mounting a material for the correction piece to the dental cutting machine to which the machining program has been input, machining the correction piece from the material using the dental cutting machine executing the machining program, measuring a dimension of a predetermined portion of the correction piece machined in the machining, calculating a correction value based on the dimension measured in the measuring, and inputting to the dental cutting machine the correction value calculated in the calculating.
