Cutting Oil Supply Control for Variable Workpiece Demand
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine tool systems fail to supply cutting oil appropriately to the cutting area based on the varying needs of different workpieces, leading to inefficiencies and potential machine stoppages due to insufficient oil levels.
Innovation Solution
A method is implemented to set specific cutting times and oil quantities for each workpiece, ensuring continuous supply by maintaining excess oil in the tank, adjusting per unit time quantities, and intermittently replenishing to prevent depletion, using inequalities to manage oil flow and storage effectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If cutting oil is supplied in a fixed quantity to the cutting-oil tank, then the supply system is simple, but the cutting oil may be insufficient for certain workpieces causing machine stoppages
Solution Approach 1:
The cutting oil supply quantity is changed from a fixed value to a dynamic value that varies according to the workpiece type. The control unit adjusts the supply quantity based on the relationship between the remaining油量 and the required油量 for different workpieces, enabling the system to adapt to varying cutting needs while maintaining operational reliability.
2Reliability
If cutting oil supply quantity is increased to ensure sufficient oil for all workpiece types, then operational reliability improves, but cutting oil waste increases for workpieces requiring less oil
Solution Approach 1:
The supply quantity parameter is dynamically adjusted based on the specific workpiece type and the current油量 level. The control unit calculates the required油量 for the current workpiece and adjusts the supply amount accordingly, preventing both insufficient oil conditions and excessive oil waste.
3Ease of operation
If cutting oil is supplied based on minimum reference quantity only, then the control method is simple, but it cannot account for different cutting oil requirements of different workpiece types
Solution Approach 1:
The control unit continuously monitors the remaining油量 in the cutting-oil tank and compares it with the required油量 for the current workpiece type. Based on this feedback, the system automatically adjusts the supply quantity to match the specific cutting needs of different workpieces, achieving both adaptability and operational simplicity.
