Oil Mist Concentration Management in Multi-Machine Factories
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In metal machining factories with multiple machine tools, oil mist generated by one tool can affect the operation of others, leading to operational failures and inefficiencies, as existing systems lack a comprehensive method to manage oil mist concentration across the entire factory environment.
Innovation Solution
An oil mist concentration management apparatus that includes a concentration acquisition unit, a determination unit, and a command unit to recognize high oil mist concentrations and adjust machine operation content, such as reducing machining speed or stopping machines with lower priority, to maintain a desired working environment by uniformly distributing oil mist.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple machine tools operate simultaneously in a factory, then productivity is improved, but oil mist concentration increases and affects operation reliability
Solution Approach 1:
The system continuously monitors oil mist concentration in the factory environment and uses this feedback to dynamically adjust machine tool operations. When concentration exceeds thresholds, the system automatically commands machines to stop or reduce speed, creating a closed-loop control that balances productivity with operational reliability
Solution Approach 2:
The system dynamically adjusts machine operation states based on real-time oil mist concentration levels. Machines transition between different operational modes (normal operation, reduced speed, stopped) according to environmental conditions, allowing flexible adaptation to maintain both productivity and reliability
2Productivity
If machine operation speed is increased, then productivity is improved, but oil mist generation increases
Solution Approach 1:
The system changes operational parameters (machining speed, operation state) based on oil mist concentration measurements. When concentration is high, the system reduces speed or stops machines; when concentration is low, machines can operate at full speed, dynamically optimizing the parameter to balance productivity and harmful emissions
3Reliability
If oil mist concentration is strictly controlled, then operation reliability is improved, but productivity decreases due to frequent machine stoppages
Solution Approach 1:
The system applies different control strategies to different machines based on their priority rankings. High-priority machines maintain operation longer while low-priority machines stop first, creating a differentiated local quality in control application that preserves overall productivity while ensuring reliability through selective management
Data Source
AI summary
An oil mist management system includes a plurality of machine tools provided in a factory, and an oil mist concentration measuring apparatus for measuring concentration of oil mist in the factory. Further, a data processing apparatus determines whether the concentration of the oil mist is larger than a threshold value, and if the concentration of the oil mist is larger than the threshold value, the data processing apparatus issues a command to decrease machining speed or stop operation of a machine tool that has the lower priority rank among the machine tools.
