Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current machine tools experience reduced machining efficiency when transitioning between machining positions on a workpiece, as the feeding device needs to lift and move significant distances, consuming time and decreasing productivity.
Innovation Solution
A machine tool design incorporating a feeding device with linear motors and a cross beam mechanism that allows the cutter to move along X, Y, and Z axes, enabling continuous machining of curved surfaces without the need for extensive repositioning, utilizing alternating magnetic fields to drive the tool holder and cutter for high-speed reciprocation along the Z-axis.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the feeding device is driven to lift and move to a second position after machining the first position, then the workpiece can be machined at different positions, but the machining efficiency is decreased due to the time-consuming repositioning process
Solution Approach 1:
The patent implements continuous machining by enabling the cutter to machine multiple positions of the workpiece without the feeding device needing to lift and reposition. The cutter moves along X, Y, and Z axes to access different positions while maintaining continuous contact with the workpiece, eliminating idle repositioning time and ensuring the useful machining action continues uninterrupted.
Solution Approach 2:
The patent introduces multi-axis movement capability, allowing the cutter to move along three dimensions (X, Y, and Z axes) to reach different positions of the workpiece. This dimensional approach replaces the traditional two-dimensional repositioning (lifting and moving in one plane) with three-dimensional motion, enabling continuous machining across the workpiece surface.
2Productivity
If the cutter moves along X, Y, and Z axes to machine curved surfaces continuously, then machining efficiency is enhanced, but the device complexity increases due to the multi-axis feeding mechanism
Solution Approach 1:
The patent combines multiple movement functions into a single integrated feeding device that can simultaneously or sequentially move the cutter along X, Y, and Z axes. This merging of translation functions into one coordinated mechanism achieves continuous multi-position machining while managing structural complexity through integration rather than separate independent mechanisms.
Solution Approach 2:
The patent employs a linear motor to drive the feeding device, replacing traditional mechanical transmission systems with direct electromagnetic drive. This substitution simplifies the mechanical structure by eliminating complex gear trains, belts, and linkages, while enabling precise control of multi-axis movement for continuous curved surface machining.
