Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional 5-axis machining centers face increased costs and size due to separate bed and column structures, which hinder the transmission of vibrations and displacements, resulting in reduced machining accuracy and inefficient chip collection.
Innovation Solution
A 5-axis machining center design where the base functions as both the bed and column, allowing rapid transmission of vibrations and displacements between rams, and enabling chips to freely fall for easy collection, while minimizing the moving path of force to enhance dynamic performance.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the bed and column are separated into distinct components, then the dynamic performance can be improved through additional equipment, but the apparatus volume increases and production costs rise
Solution Approach 1:
The patent merges the bed and column into a single integrated base structure. The base serves dual functions as both the bed (supporting the saddle and column) and the column (supporting the spindle), eliminating the need for separate components and reducing overall apparatus volume while maintaining structural integrity.
Solution Approach 2:
The base is designed as a multi-functional component that simultaneously performs the functions of both the bed and column. It provides support for the saddle, carries the column structure, and anchors the spindle assembly, thereby reducing the number of parts needed while preserving dynamic performance.
2Reliability
If the bed and column are separated, then dynamic performance can be enhanced, but vibrations and displacements cannot be transmitted between axes, reducing machining accuracy
Solution Approach 1:
By integrating the bed and column into one base structure, the patent creates continuous rigid connections between all axes. Vibrations and displacements generated during machining are rapidly transmitted across the integrated base, minimizing relative movements between axes and improving machining accuracy.
Solution Approach 2:
Instead of separating components to improve dynamic performance (conventional approach), the patent inverts the approach by integrating components. This integration creates a rigid framework where vibrations are quickly dissipated across the entire structure, achieving both dynamic performance and machining accuracy.
3Ease of manufacture
If the bed and column are integrated into one base, then production costs are reduced and structure is simplified, but additional equipment would be needed to maintain dynamic performance
Solution Approach 1:
The integration of bed and column into a single base reduces the number of parts to manufacture and assemble, lowering production costs. The integrated design maintains dynamic performance through inherent structural rigidity and direct force transmission paths, eliminating the need for additional dynamic performance enhancement equipment.
Solution Approach 2:
The multi-functional base performs multiple structural roles simultaneously, reducing overall component count and manufacturing complexity. By designing the base to handle both bed and column functions with optimized rigidity, the patent achieves cost reduction without compromising dynamic performance.
4Ease of manufacture
If chips are not allowed to freely fall, then chip collection becomes difficult, but the structure becomes more complex
Solution Approach 1:
The patent designs the machining area with a sloped or inclined surface that allows chips to freely fall under gravity toward collection points. This passive chip evacuation system uses gravitational force naturally, eliminating the need for complex active chip removal mechanisms while improving chip collection efficiency.

AI summary
The present invention relates to a machining center, and more particularly, to a machining center which allows a bed and a column to be integrated, thereby being capable of reducing the overall size of the apparatus and saving production costs and allows vibrations and displacements occurring in each of 5 axes to be rapidly transmitted to other axes to minimize relative vibrations and displacements between the axes, thereby being capable of performing high-precision machining.
