Multi-Plane Machining Unit Layout to Prevent Tool Interference
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing processing systems for workpieces, such as wood or plastic, face inefficiencies due to tool changes causing non-productive times and tool interference during machining operations like drilling and milling.
Innovation Solution
A processing unit with a body featuring two perpendicular tool holders spaced along its longitudinal direction, allowing for simultaneous or sequential use of multiple tools without interference, and a drive system to power these tools, reducing idle times and enabling efficient machining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple tools are arranged around the circumference of the machining unit, then the machining unit can accommodate multiple tools for various machining operations, but the tools may interfere with each other during machining
Solution Approach 1:
The patent transitions from arranging tools in a single circumferential plane to distributing tools across multiple planes spaced apart in the longitudinal direction. This dimensional change eliminates tool interference while preserving multi-tool capability, as tools in different longitudinal planes cannot interfere with each other's machining paths
2Device complexity
If tools are arranged in a single plane around the machining unit, then the structure is simpler, but tool interference occurs and machining is prevented
Solution Approach 1:
By introducing the longitudinal dimension to space tool holders at different positions along the machining unit's length, the patent achieves both structural feasibility and interference-free operation, thereby maintaining productivity without excessive complexity
3Adaptability or versatility
If tool changes are performed frequently to perform various machining operations, then different machining tasks can be completed, but non-productive time increases
Solution Approach 1:
The patent combines multiple tool holders into a single integrated machining unit that can accommodate multiple tools simultaneously. This allows the machining unit to perform various machining operations without requiring tool changes, thereby eliminating non-productive time while maintaining versatility
Solution Approach 2:
The machining unit is designed with multiple tool holders that can accommodate different tool types (drilling, milling, etc.), making the single machining unit universal for performing multiple machining operations without requiring tool changes
