Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing systems for operation verification of machine tools may not accurately reflect three-dimensional data, leading to incomplete or inaccurate representation of machine tool operations, especially when sensors fail to provide reliable data.
Innovation Solution
A computer system that acquires operating data from machine tools, generates computer graphics to simulate the operation, and compares these graphics with real-time images to detect abnormalities, identifying the component causing the issue by analyzing positional relationships and timing of discrepancies.

Engineering Contradiction Analysis
1Extent of automation
If sensor data is used to generate three-dimensional data for operation verification, then the verification process can be automated, but the accuracy of the three-dimensional data deteriorates when the sensor fails
Solution Approach 1:
The patent creates a computer graphics model (virtual copy) of the machine tool that replicates its operational states. This virtual model is generated by processing sensor data through a computer program, allowing operation verification without direct reliance on real-time sensor accuracy. The copying principle resolves the contradiction by creating a reliable virtual representation that can be verified even when physical sensors fail.
Solution Approach 2:
The patent introduces a computer program as an intermediary between the sensor data and the three-dimensional representation. This intermediary processes and transforms raw sensor data into a verified computer graphics model, adding a layer of validation and error correction that maintains accuracy even when sensor data quality deteriorates.
2Device complexity
If traditional sensor-based three-dimensional data acquisition is used, then data collection is simplified, but the ability to detect operational abnormalities deteriorates
Solution Approach 1:
The patent implements a feedback mechanism by comparing the computer graphics model with actual operation images. The comparison unit analyzes discrepancies between the virtual model and real-world observations, providing feedback that enables reliable abnormality detection. This feedback loop maintains high reliability while keeping the data acquisition process relatively simple.
Solution Approach 2:
The patent replaces direct mechanical/sensor-based observation with a computational approach. Instead of relying solely on physical sensors to detect abnormalities, the system uses computer graphics processing and image comparison algorithms to identify operational issues, substituting mechanical detection with computational analysis.

AI summary
Provided are a computer system, and a method and a program for operation verification that easily know the operation of a machine tool more exactly. The computer system acquires operating data while a machine tool operates for a predetermined time, generates computer graphics virtually showing that the machine tool operates for the predetermined time from the acquired data, acquires an image of the machine tool that has taken for the predetermined time, and compares the image with the computer graphics for the predetermined time. The computer system also notifies the abnormality if an abnormality has been detected as the result of the comparison.
