Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional electrochemical machining (ECM) technologies face limitations in producing complex shapes with multiple orientations and high precision due to restrictions on electrode alignment, making it difficult to simultaneously machine multiple points and angles, especially in industries like aerospace and automotive where complex features are required.
Innovation Solution
An electrochemical machining apparatus and method utilizing multiple electrode members with free ends, guided by a guiding member and actuated by an actuation member to form angle variations, allowing for the simultaneous machining of multiple points and angles by controlling the movement and orientation of the conductive ends within a pressure box filled with electrolyte.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional electrochemical machining uses a single electrode with fixed alignment, then the machining process is simple to control, but it cannot simultaneously machine multiple points and angles or produce complex shapes with multiple orientations
Solution Approach 1:
The single electrode is divided into multiple separate electrode members (at least two), each capable of independent positioning and angle adjustment. This segmentation allows each electrode to target specific points and angles on the workpiece, enabling simultaneous multi-point and multi-angle machining while maintaining relatively simple individual electrode structures.
Solution Approach 2:
The electrode members are positioned in three-dimensional space with varying coordinates and orientations. By utilizing spatial dimensionality, the system can machine multiple points and angles simultaneously without requiring complex alignment mechanisms for each individual electrode, as the positioning is achieved through spatial arrangement rather than complex mechanical alignment.
2Shape
If conventional ECM uses rigid electrode alignment, then the electrode structure is simple, but it cannot form complex shapes requiring multiple orientations
Solution Approach 1:
Multiple separate electrode members are used instead of a single rigid electrode structure. Each electrode member can be independently oriented and positioned to create different facets and angles of complex shapes, providing the necessary orientation flexibility without requiring a single complex adaptable structure.
Solution Approach 2:
The electrode members are positioned and oriented dynamically during the machining process to match the varying angles and orientations required for different portions of the workpiece. This dynamic positioning capability allows the system to adapt to complex shape requirements while maintaining simple, rigid electrode structures.

Enables the creation of complex, high-precision shapes with increased machining efficiency and reduced costs by allowing for the simultaneous machining of multiple points and angles, overcoming the limitations of traditional ECM technologies.
Implementation Method 1
Electrolyte 103 fills between the work piece 101 and the electrode 102. When applying a voltage, the current passes through the Electrolyte 103 from the electrode 102 and into the work piece 101. Owing to the electrochemical action, material is removed from the work piece 101 as a metal hydroxide.

AI summary
An electrochemical machining apparatus being capable of performing multiple points and multiple angles machining is provided. The electrochemical machining apparatus includes at least one electrode member, a guiding member and an actuation member. The electrode member includes a conductive end and a free end, wherein the electrode member is rigid and unbendable. The guiding member is for limiting and guiding the electrode member to move. The actuation member is for exerting a force to the free end of the electrode member, thereby enabling the conductive end of the electrode member to form angle variations. A force-exerting direction from the actuation member to the free end is parallel to a central axis of the electrode member or deflects off the central axis so as to form the angle variations.
