Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Stability of the object's composition
If a single traverse acceleration parameter is set too large to control vibrations of the machine structure, then surface ripples on the workpiece would be inevitable
Solution Approach 1:
The system dynamically adjusts traverse acceleration parameters based on real-time detection of machine structure vibrations and servo motor current values. Instead of using a fixed conservative parameter, the system continuously optimizes acceleration settings during operation to maintain stability while preventing surface ripples.
Solution Approach 2:
The system implements a feedback mechanism where vibrations and motor current values are continuously measured and fed back to adjust acceleration parameters. This closed-loop control allows the system to respond to actual machine behavior rather than relying on predetermined conservative settings.
2Reliability
If conservative manner is held by maintenance personnel while adjusting parameters of foreign controllers, then optimal operation state of the machine tool would be hard to be achieved
Solution Approach 1:
The system enables automatic self-optimization of acceleration parameters without requiring manual intervention by maintenance personnel. The automated detection and adjustment system eliminates the need for conservative manual tuning while achieving optimal operation state, thereby improving productivity without sacrificing reliability.
Solution Approach 2:
The system automatically changes acceleration parameters based on detected vibrations and motor current values, transitioning from static conservative settings to dynamic optimized parameters. This automated parameter optimization resolves the contradiction between safety and efficiency.
3Adaptability or versatility
If traverse acceleration parameters are manually adjusted by maintenance personnel, then understanding requirements for different machine tools would be needed, but this leads to time-consuming adjustment process
Solution Approach 1:
The system automatically detects machine characteristics and adjusts parameters without requiring maintenance personnel to understand or manually configure settings for different machine tool types. This self-service capability maintains adaptability while eliminating time-consuming manual adjustment processes.
Solution Approach 2:
The system replaces manual mechanical adjustment processes with automated electronic detection and control. By substituting human operators with automated sensors and control algorithms, the system achieves both adaptability and time efficiency.

AI summary
A system for acceleration adjustment of machine tool at rapid traverse includes a signal measurement module, a signal judgment module and an acceleration optimization module. The machine tool has a servo motor and a working platform. The signal measurement module measures signals while the servo motor drives the working platform from a first specific position to a second specific position, or from the second specific position back to the first specific position. The signal judgment module judges whether the actual maximum current value of the motor is equal to the manufacturer's specification according to the signals; and if negative, the acceleration optimization module calculates and optimizes an axial acceleration till an optimal value is achieved. Then, a curve smoothing time of the optimal acceleration is calculated and optimized by the acceleration optimization module. In addition, a method for acceleration adjustment of machine tool at rapid traverse is provided.
