Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current monitoring controllers for CNC machines in large-scale production environments are limited in their ability to perform complex data analysis for single or multiple CNC machines, inhibiting effective monitoring and preventive maintenance.
Innovation Solution
A system comprising a CNC machining system and a machine edge controller that acquires data from sensors and control signals to compare with baseline parameters, enabling real-time monitoring and detection of abnormal operations, and performing corrective actions such as stopping the machining operation or issuing notifications.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a dedicated monitoring controller is used for each CNC machine, then simple diagnostics can be performed, but complex data analysis for single or multiple CNC machines is inhibited
Solution Approach 1:
The patent consolidates monitoring capabilities for multiple CNC machines into a single centralized monitoring controller. This controller aggregates data from multiple sources and performs both simple diagnostics and complex data analysis functions, eliminating the limitation where each dedicated controller could only perform simple diagnostics. The merged system provides comprehensive monitoring and advanced analytics across the entire machining system.
2Productivity
If multiple CNC machines are monitored individually, then each machine can be tracked, but effective monitoring and preventive maintenance across the system is inhibited
Solution Approach 1:
The centralized monitoring controller implements feedback mechanisms that continuously collect operational data from multiple CNC machines, analyze trends, and provide actionable insights for preventive maintenance. The system processes real-time data, compares it against baseline parameters, and generates feedback loops that enable proactive maintenance scheduling, thereby improving both monitoring coverage and preventive maintenance effectiveness across the entire system.

AI summary
A system includes a computer numerical control (CNC) machining system configured to perform a machining operation to define a feature on a workpiece and a machine edge controller disposed external of the machining system and in communication with the CNC machine system. The machine edge controller is configured to perform a machining evaluation during the machining operation. In executing the machining evaluation, the machine edge controller is configured to acquire data indicative of characteristics of the CNC machining system during the machining operation and compare the data with one or more machining baseline parameters associated with the machining operation to determine an abnormal operation of the CNC machining system. The one or more machining baseline parameters define a nominal response of the CNC machining system for performing the machining operation.
