Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Traditional machining methods lack precision and effective material removal, particularly in complex components with high tolerance requirements, as they often rely on vertical or horizontal tool orientations that can lead to vibration and inefficient chip management.
Innovation Solution
A machining device with a trunnion table that pivots around a horizontal axis and a spindle that moves in a plane parallel to the horizontal plane, allowing the cutting tool to work from below, thereby utilizing gravity for chip removal and providing a stable platform with multiple degrees of freedom for precise machining.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Manufacturing precision
If traditional vertical or horizontal milling machines are used, then the machining process can be performed, but vibration occurs and precision deteriorates
Solution Approach 1:
The patent inverts the traditional machining configuration by having the cutting tool work from below the workpiece instead of from above or the side. This inversion changes the gravitational interaction, allowing chips to fall away naturally and reducing vibration, thereby improving both stability and precision
2Productivity
If traditional machining orientations are used, then the tool can access the workpiece, but chip removal becomes inefficient
Solution Approach 1:
The patent positions the cutting tool below the workpiece at a level where gravity can act directly on the chips, creating an equipotential condition where chips naturally fall away from the machining zone without requiring additional removal mechanisms, thus improving productivity and eliminating chip accumulation problems
3Manufacturing precision
If the cutting tool works from above or the side, then traditional machining can be performed, but precision and stability are reduced
Solution Approach 1:
The patent inverts the traditional machining configuration by having the cutting tool work from below the workpiece instead of from above or the side. This inversion changes the gravitational interaction, allowing chips to fall away naturally and reducing vibration, thereby improving both stability and precision

AI summary
A machining device is provided. The machining device includes a trunnion table adapted to hold a workpiece and arranged to pivot around a pivot axis using a pivoting motor. The pivot axis is parallel to a horizontal plane. A spindle is adapted to hold a cutting tool directed upwards and arranged to be moved in a plane parallel to the horizontal plane by a spindle transporting device. A trunnion table transporting device is adapted to vertically transport the trunnion table towards and away from the cutting tool, such that in a cutting state, chips cut from the workpiece are removed from the workpiece by gravity.
