Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If a predetermined amount of cutting fluid is discharged from nozzles during machining, then the cooling and lubrication functions are maintained, but cutting fluid is wasted at positions where it is not sprayed on the workpiece
Solution Approach 1:
The patent implements dynamic adjustment of cutting fluid discharge amounts based on real-time machining conditions. The control device receives information about machining state, tool type, and cutting fluid temperature, then dynamically calculates and adjusts the discharge amount for each nozzle to match actual cooling and lubrication needs, eliminating waste while maintaining effectiveness
Solution Approach 2:
The system changes the discharge amount parameter of cutting fluid based on multiple factors including machining state (rough or finish machining), tool type, and cutting fluid temperature. By adjusting this parameter dynamically rather than using a fixed predetermined amount, the system optimizes both efficiency and effectiveness
2Temperature
If the discharge amount of cutting fluid is increased to ensure adequate cooling, then cooling effectiveness is improved, but cutting fluid consumption increases
Solution Approach 1:
The control device adjusts the discharge amount parameter based on cutting fluid temperature and machining conditions. When cutting fluid temperature is high or machining generates excessive heat, the system increases discharge amount to maintain cooling effectiveness. When conditions allow, it reduces discharge to minimize consumption
Solution Approach 2:
The system uses feedback from machining state information and cutting fluid temperature to continuously optimize discharge amounts. The control device receives real-time data about machining conditions and adjusts cutting fluid discharge accordingly, ensuring adequate cooling only when and where needed
3Loss of energy
If the discharge amount is adjusted based on machining conditions, then cutting fluid usage efficiency is improved, but the device complexity increases
Solution Approach 1:
The control device performs multiple functions: it receives machining state information, determines tool types, monitors cutting fluid temperature, calculates appropriate discharge amounts, and controls nozzle operations. By consolidating these diverse functions into a single multi-functional control device, the system achieves complex optimization without proportionally increasing overall system complexity
Solution Approach 2:
The control device automatically determines discharge amounts based on received machining information without requiring manual intervention. It self-adjusts the cutting fluid discharge by controlling valve openings based on calculated requirements, eliminating the need for operator adjustment and reducing operational complexity
