Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine tools face issues with cross talk between axes, large footprint, and inefficient energy consumption during machining of complex parts with curved surfaces, particularly in aerospace and power generation applications, affecting machining quality and reliability.
Innovation Solution
A machine tool design with a spindle vertically oriented and fewer linear axes on the workpiece side, featuring parallel alignment of linear and swivel axes to eliminate cross talk, optimized for 5-axis simultaneous machining with a compact footprint and improved energy efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the swivel axis and linear axis are arranged non-parallel, then the machine can perform five-axis machining, but cross talk is generated during acceleration affecting machining quality
Solution Approach 1:
The patent applies asymmetry by deliberately arranging the swivel axis parallel to the linear axis rather than using conventional perpendicular arrangements. This asymmetric configuration eliminates cross talk between axes during acceleration while maintaining five-axis machining capability, directly resolving the contradiction between versatility and precision.
2Area of stationary object
If the vertical axis is arranged on the side of the workpiece, then the machine structure is compact, but cross talk occurs between the vertical linear axis and swiveling table under heavy workpiece load
Solution Approach 1:
The patent inverts the conventional arrangement by placing the vertical linear axis on the spindle side rather than the workpiece side. This inversion eliminates cross talk between the vertical axis and swiveling table under heavy loads, while the machine maintains a compact footprint through optimized spatial configuration.
3Adaptability or versatility
If multiple linear axes are arranged on the workpiece side, then the machine can handle complex workpieces, but energy consumption increases due to moving heavy workpiece mass
Solution Approach 1:
The patent segments the linear axes between the workpiece side and spindle side, with only one linear axis (X-axis) arranged on the workpiece side. This segmentation reduces the mass that needs to be accelerated during machining operations, significantly lowering energy consumption while maintaining the capability to handle complex workpieces through five-axis simultaneous machining.
