Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 5-axis machining centers face challenges in reducing production costs, miniaturization, and minimizing relative displacements between axes, leading to increased costs, larger volumes, and reduced machining accuracy due to separated column and bed structures, which hinder dynamic performance and chip collection.
Innovation Solution
A 5-axis machining center design where a single base functions as both the bed and column, integrating the Z-axis and X-axis rams with a pentagonal pillar structure, allowing rapid transmission of vibrations and displacements between axes, and incorporating a tool magazine for efficient chip collection.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the column and bed are separated in conventional 5-axis machining centers, then the spindle can move on three axes and the workpiece can rotate on two axes enabling 5-axis machining capability, but the apparatus volume increases and production costs increase
Solution Approach 1:
The patent merges the column and bed into a single integrated base structure. The base is designed with a pentagonal pillar configuration that simultaneously provides the functions of both the column (supporting spindle movement in Y and Z axes) and the bed (supporting table movement in X axis). This integration eliminates the need for separate column and bed components, reducing apparatus volume while maintaining full 5-axis machining capability.
2Adaptability or versatility
If the column and bed are separated in conventional 5-axis machining centers, then 5-axis machining is enabled, but the structure becomes complex and production costs increase
Solution Approach 1:
The patent combines the column and bed into one integrated base structure, reducing the number of components and simplifying the overall structure. The pentagonal pillar design provides multiple functional surfaces that support both spindle and table movements, eliminating the need for separate column and bed assemblies and their associated mounting interfaces.
Solution Approach 2:
The integrated base structure serves multiple functions simultaneously: it supports the spindle assembly for Y and Z axis movements, supports the table assembly for X axis movement, and provides rigid structural support for all five axes of machining. This multi-functionality reduces structural complexity while maintaining 5-axis capability.
3Adaptability or versatility
If the column and bed are separated, then 5-axis machining is enabled, but vibrations and thermal displacements are difficult to transmit between axes reducing machining accuracy
Solution Approach 1:
By integrating the column and bed into a single base structure, the patent creates continuous rigid structural paths that enable efficient transmission of vibrations and thermal displacements between all axes. The integrated design eliminates the interfaces between separate column and bed components, which were acting as barriers to vibration and thermal transmission, thereby improving machining accuracy.
4Reliability
If additional equipment is added to increase dynamic performance, then the machining center can operate, but the apparatus volume increases and production costs increase
Solution Approach 1:
The integrated base structure with its pentagonal pillar design provides multiple functional surfaces and mounting points that enable all five axes of movement without requiring additional supporting equipment. The structure itself is designed to provide the necessary dynamic performance through its rigid construction and optimized geometry, eliminating the need for extra volume-consuming components.
