Focused Ion Beam Control for Multi-Condition Region Machining
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing focused ion beam apparatuses can only set one machining condition for each machining region, requiring users to repeatedly set machining regions when changing conditions, which is inefficient and time-consuming.
Innovation Solution
A focused ion beam apparatus that allows users to set multiple machining conditions for a single machining region, enabling the optical system to scan the region based on these conditions, eliminating the need for repeated region setting.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of operation
If only one machining condition is set for one machining region, then the system is simple to operate, but the user has to set the machining region many times to continue machining while changing machining conditions
Solution Approach 1:
The machining region setting is made universal by allowing multiple different machining conditions to be associated with the same machining region. The control unit stores and manages multiple sets of machining conditions (first machining condition, second machining condition, etc.) for a single machining region, enabling the system to switch between different conditions without requiring the user to re-set the region boundaries each time.
2Manufacturing precision
If the user sets the machining region many times to change machining conditions, then each condition can be applied correctly, but the operation becomes inefficient and time-consuming
Solution Approach 1:
The system performs preliminary action by pre-storing multiple sets of machining conditions in the control unit before actual machining begins. The control unit holds a first machining condition and a second machining condition ready for use, allowing the machining process to switch between conditions without interruption or re-setting of the region, thereby maintaining precision while improving efficiency.
3Productivity
If multiple machining conditions are stored for one region, then machining can continue with varied conditions without re-setting, but the control system becomes more complex
Solution Approach 1:
The control unit performs self-service by automatically managing the storage and selection of multiple machining conditions. The system itself handles the complexity of managing multiple conditions (first machining condition, second machining condition, etc.) without requiring additional user intervention or complex external control mechanisms, thereby enabling continuous machining with varied conditions while keeping the user interface simple.
