Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing cutting parts for lathes have complex structures, making them time-intensive and costly to produce, and they often require lead-containing materials to prevent long flow cuttings, which poses health risks.
Innovation Solution
A cutting part with a flat structure, preferably a herringbone pattern, is designed for the lathe tool head, featuring a middle stem and burrs that are laser-engraved to break cuttings, allowing for easy production and use of lead-free materials, with the structure's simplicity reducing manufacturing complexity and cost.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If complex cutting part structures with concave surfaces and projections are used to break cuttings, then cutting breaking effectiveness is improved, but device complexity and manufacturing cost increase significantly
Solution Approach 1:
The patent replaces complex mechanical cutting part structures with a laser-based system. The laser beam (electromagnetic energy) is used to ablate material and create cutting-breaking features dynamically, eliminating the need for pre-manufactured complex mechanical structures with concave surfaces and projections. This substitution of mechanical manufacturing with laser processing resolves the contradiction by achieving effective cutting breaking without increasing device complexity.
Solution Approach 2:
The cutting part structure is made dynamically adjustable through laser processing. Instead of fixed complex structures, the system can dynamically create and modify cutting-breaking features on the cutting part surface during operation or between operations. This dynamic capability allows the system to achieve effective cutting breaking while maintaining simple base structures, resolving the contradiction between effectiveness and complexity.
2Reliability
If lead-containing materials are used in workpieces to improve machinability and prevent long flow cuttings, then cutting breaking is improved, but health risks increase
Solution Approach 1:
The patent uses laser processing to create cutting-breaking features directly on the cutting part, eliminating the need for lead-containing workpiece materials. The laser (electromagnetic energy) creates effective cutting breaking through controlled material removal and structure modification, providing a healthy alternative to lead-based solutions while maintaining cutting breaking performance.
Solution Approach 2:
The patent changes the approach from modifying workpiece material composition (adding lead) to modifying cutting part surface characteristics through laser processing. By changing the surface parameters of the cutting part (creating micro-structures, roughness, or geometric features) via laser, the system achieves effective cutting breaking without introducing harmful substances, resolving the contradiction between performance and health safety.
3Ease of manufacture
If traditional material removal methods are used to create cutting part structures, then manufacturing flexibility is maintained, but production time and cost increase
Solution Approach 1:
The patent replaces traditional mechanical material removal methods (milling, drilling, machining) with laser processing. The laser beam directly removes or modifies material through thermal vaporization and ablation, dramatically reducing production time while maintaining full manufacturing flexibility. This substitution resolves the contradiction by enabling rapid prototyping and customization without the time-consuming nature of traditional mechanical manufacturing.
Solution Approach 2:
The laser processing system can rapidly copy or replicate cutting part structures by digitally controlling the laser path and parameters. Instead of time-consuming mechanical tooling and setup, the system uses digital models to guide laser processing, enabling quick reproduction of complex cutting part geometries. This copying capability through digital control resolves the contradiction between manufacturing flexibility and production time.
