Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine tool systems lack an effective method to supply cutting oil to cutting-oil tanks and areas in appropriate quantities, leading to inefficiencies and potential stoppages due to varying oil requirements based on different types of work pieces being cut.
Innovation Solution
A method involving a flow measuring meter and controller to monitor and adjust the supply of cutting oil, ensuring a supply quantity per unit time that exceeds the discharge rate, with periodic replenishment to maintain a minimum reference quantity in the tank, thereby preventing oil depletion and ensuring continuous supply.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If cutting oil is supplied to a cutting-oil tank as a matter of course without adjustment, then the tank will have cutting oil available, but the quantity may be insufficient for different work pieces causing stoppages
Solution Approach 1:
The system uses a flow measuring meter to continuously monitor the discharge quantity of cutting oil from the tank, and the controller adjusts the supply quantity based on this feedback to match the actual consumption rate, ensuring the tank maintains adequate oil levels for continuous operation
Solution Approach 2:
The system pre-supplies cutting oil to the tank in advance based on measured discharge rates before the tank runs out, preventing stoppages by ensuring oil is available before depletion occurs
2Reliability
If cutting oil supply quantity is increased to prevent depletion, then continuous supply is ensured, but oil may be wasted when not needed
Solution Approach 1:
The cutting oil supply quantity is dynamically adjusted based on the actual discharge rate measured by the flow measuring meter, allowing the system to match supply with demand rather than using fixed supply rates, thus preventing both depletion and waste
Solution Approach 2:
The supply quantity parameter is changed based on measured discharge quantities and work piece types, allowing optimization of oil usage by adjusting the parameter to match actual consumption needs
3Adaptability or versatility
If cutting oil supply is adjusted for each work piece type, then appropriate quantity is supplied, but system complexity increases
Solution Approach 1:
The system automatically measures discharge quantities and determines appropriate supply rates without manual intervention, using the flow measuring meter and controller to self-adjust supply parameters based on work piece type and measured consumption
Solution Approach 2:
The flow measuring meter and controller serve multiple functions: measuring discharge rate, determining supply quantity, and adapting to different work piece types, reducing overall system complexity through multi-functional components
