Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Small and medium-sized enterprises face the challenge of performing five-axis machining without the high cost of a five-axis machine tool, as existing three-axis machine tools are not capable of this advanced machining without significant cost and efficiency penalties.
Innovation Solution
A detachable assembly for a three-axis machine tool that adds two additional machining directions, allowing it to perform five-axis machining by incorporating a first table rotator for C-axis motion and a second table rotator for A-axis motion, powered by a motor control system and hydraulic pressure control system, respectively.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If a five-axis machine tool is purchased to perform five-axis machining, then machining capability is improved, but cost and unit price increase significantly
Solution Approach 1:
The patent applies multi-functionality by enabling a three-axis machine tool to perform both three-axis and five-axis machining through a detachable assembly. The assembly includes a table member that can be mounted on the existing three-axis machine tool table, adding two rotational axes (A-axis and C-axis) to the original three linear axes, thus providing five-axis machining capability without requiring a dedicated five-axis machine tool.
Solution Approach 2:
The patent segments the five-axis machining system into a modular detachable assembly that can be independently mounted on the three-axis machine tool. The assembly consists of separate components including a table member, first table rotator for C-axis rotation, second table rotator for A-axis rotation, and power providers, allowing the three-axis machine tool to maintain its original functionality while adding five-axis capability through this separable module.
2Adaptability or versatility
If a five-axis machine tool is purchased to perform five-axis machining, then machining capability is improved, but work efficiency and cost-effectiveness deteriorate
Solution Approach 1:
The detachable assembly enables the three-axis machine tool to universally perform both three-axis and five-axis machining operations. The assembly includes a table member with first and second table rotators that provide A-axis and C-axis rotations, allowing the machine to handle complex five-axis machining tasks while maintaining its original three-axis functionality, thus improving work efficiency and cost-effectiveness.
3Adaptability or versatility
If a detachable assembly is added to a three-axis machine tool to enable five-axis machining, then adaptability is improved, but device complexity increases
Solution Approach 1:
The patent segments the five-axis addition into a modular detachable assembly that can be independently mounted on the three-axis machine tool. The assembly consists of separate components including a table member, first table rotator for C-axis rotation, second table rotator for A-axis rotation, and power providers, allowing the three-axis machine tool to maintain its original functionality while adding five-axis capability through this separable module.
Solution Approach 2:
The detachable assembly employs a nested structure where the first table rotator is disposed inside the second table rotator. The first rotator casing containing the C-axis rotation mechanism is positioned within the second rotator casing that provides A-axis rotation, creating a compact nested arrangement that reduces overall structural complexity while providing both rotational axes.
4Adaptability or versatility
If a detachable assembly is added to a three-axis machine tool to enable five-axis machining, then adaptability is improved, but ease of manufacture worsens
Solution Approach 1:
The patent segments the five-axis addition into a modular detachable assembly that can be independently mounted on the three-axis machine tool. The assembly consists of separate components including a table member, first table rotator for C-axis rotation, second table rotator for A-axis rotation, and power providers, allowing the three-axis machine tool to maintain its original functionality while adding five-axis capability through this separable module.
