Machine Tool Deviation Signal External Storage
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current machine tool monitoring systems require direct operator intervention to detect deviations between target and current signals, leading to potential misinterpretation or ignoring of warning messages, which can result in machine damage or quality reduction.
Innovation Solution
A process and system for monitoring machine tools that involves determining target and current signals, detecting deviations, and generating a deviation signal, which is then transferred to an externally accessible storage unit for external detection and display, allowing for timely correction or repair before machine failure.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If deviation detection is performed only on the machine tool display, then the operator can directly see warnings, but the risk of misinterpretation or ignoring warnings increases
Solution Approach 1:
The patent introduces an intermediary system consisting of a communication interface and external display device that mediates between the machine tool's deviation detection system and the operator. The deviation information is transmitted via communication interface (e.g., USB, Ethernet) to external display devices (smartphones, tablets, computers), creating an intermediate layer that ensures warning information is reliably conveyed without being subject to operator interpretation errors or oversight at the machine display alone.
Solution Approach 2:
The patent extends the warning display from the traditional single dimension (machine tool display only) to multiple dimensions by enabling access through various external devices and locations. Operators can view deviation warnings on smartphones, tablets, or computers both at the machine location and remotely, adding spatial and device diversity to the warning delivery system, thereby reducing the chance of missed or misinterpreted alerts.
2Ease of operation
If remote maintenance is performed by concrete inquiry and clearance of access, then machine tools can be maintained remotely, but the response time and efficiency may be limited
Solution Approach 1:
The patent implements a feedback mechanism where deviation information is continuously monitored and automatically transmitted to external display devices and maintenance personnel. When a deviation occurs, the system provides immediate feedback through multiple channels (machine display, external devices, remote notifications), enabling maintenance personnel to respond promptly without waiting for operator inquiries or manual access requests, thereby reducing maintenance response time while maintaining ease of remote operation.
3Manufacturing precision
If deviation signals are not externally accessible, then the machine tool system remains simple, but systemic defect detection and quality control are limited
Solution Approach 1:
The patent makes the deviation signal universally accessible by implementing a communication interface that can connect to multiple types of external devices (smartphones, tablets, computers, central monitoring systems). The same deviation signal serves multiple functions: local warning display, remote notification, data logging, and integration with quality control systems. This multi-functional approach enhances quality control and systemic defect detection capabilities without proportionally increasing system complexity, as the communication interface handles multiple purposes simultaneously.
Data Source
AI summary
A device, system, method, business method, and process of monitoring at least one machine tool including: determining a target signal of a component of the machine tool when performing a work step on the basis of at least one pre-definable or predefined reference number; detecting a current signal of the component of the machine tool when performing the work step; detecting a deviation of the target signal from the current signal; and generating a deviation signal. The deviation signal includes a piece of information about the component, the machine tool, and/or the deviation. The device, system, method, business method, and process of monitoring at least one machine tool further includes transferring the deviation signal as a new data set to an externally accessible storage unit that is separate or separable from the machine tool.
