1Manufacturing precision
If traditional micro-nano manufacturing technologies (photolithography, electroplating) are used, then manufacturing capability is provided, but inability to efficiently produce high-precision 3D complex structural parts occurs
Solution Approach 1:
The patent combines laser processing technology with localized electrochemical deposition to form a composite processing system. The laser provides high-precision material removal and shaping capabilities, while electrochemical deposition adds material with controlled composition and crystal structure. This merging allows simultaneous achievement of high manufacturing precision for complex 3D structures and improved productivity through automated multi-axis control.
Solution Approach 2:
The invention implements dynamic multi-axis control systems that enable real-time adjustment of processing parameters including laser power, deposition current density, and electrode positions. The system dynamically coordinates five-axis motion control to maintain optimal processing conditions throughout the manufacturing of complex 3D structures, thereby achieving both high precision and efficient production.
2Manufacturing precision
If laser processing technology is used, then high-precision and high-efficiency material processing is achieved, but deficiency in manufacturing complex microstructures occurs
Solution Approach 1:
The patent merges laser processing with electrochemical deposition to create a composite manufacturing system that retains the high precision of laser technology while gaining the ability to manufacture complex microstructures through controlled material deposition. The electrochemical component enables formation of intricate geometries and composite materials that laser alone cannot achieve.
Solution Approach 2:
The composite processing system performs multiple functions: laser-based material removal and shaping, electrochemical deposition of complex microstructures, and controlled composition adjustment. This multi-functionality allows the system to handle diverse manufacturing requirements for complex microstructures while maintaining high precision.
3Power
If laser and electrochemical composite deposition is implemented, then instantaneous high power and non-contact processing are achieved, but difficulty in process integration limits application to plane coating only
Solution Approach 1:
The patent segments the composite deposition process into independently controllable modules: laser processing unit, electrochemical deposition unit, and multi-axis motion control unit. Each module can be optimized and controlled separately, reducing the overall system complexity while maintaining the benefits of high power laser processing and electrochemical deposition.
Solution Approach 2:
The invention introduces a sophisticated control system as an intermediary that coordinates between the laser and electrochemical deposition processes. This mediator manages the complex interactions, synchronizes processing parameters, and handles the five-axis motion control, thereby simplifying the operational complexity despite the advanced capabilities.
4Manufacturing precision
If localized electrochemical deposition is used, then control of material composition and crystal structure is achieved, but processing efficiency and quality need improvement
Solution Approach 1:
The patent implements dynamic control of electrochemical deposition parameters including current density, voltage, and electrolyte composition during the processing. The system dynamically adjusts these parameters based on real-time feedback and pre-programmed sequences, enabling both precise control of material properties and improved processing efficiency through optimized deposition rates.
Solution Approach 2:
The invention enables continuous processing by coordinating laser and electrochemical deposition operations in a seamless manner. The five-axis motion control system ensures continuous positioning of the processing head, while the electrochemical deposition operates continuously with controlled parameter variations, thereby improving overall productivity while maintaining material quality control.
