Numerical Control System Centralized Tool Catalog Database
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Operators face a heavy burden in manually inputting tool shape and cutting condition data for each machine tool, as existing systems lack a centralized database for sharing optimal machining conditions, leading to inefficiencies and the inability to share machining know-how among workers.
Innovation Solution
A numerical control system with a tool catalog database that aggregates and updates cutting condition data for each tool, allowing data to be shared among machines and updated based on actual machining conditions, eliminating the need for manual input and enabling the accumulation and sharing of optimal machining conditions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Ease of manufacture
If a tool catalog database is prepared for each tool manufacturer or type, then tool information can be stored systematically, but operators must manually input data and bring multiple catalogs to the job site, increasing operational burden
Solution Approach 1:
The patent merges multiple tool catalogs from different manufacturers and types into a single centralized tool catalog database that can be accessed by all numerical controllers on the network. This eliminates the need for operators to carry multiple separate catalogs and manually input data, as all tool information is now available in one unified database through automatic data transmission.
Solution Approach 2:
The patent introduces a centralized tool catalog database as an intermediary between tool manufacturers and numerical controllers. This database receives tool information from manufacturers and makes it accessible to all controllers automatically, eliminating the manual data input process and serving as a mediator that streamlines information flow across the machining system.
2Productivity
If cutting conditions are manually input based on catalog examples, then machining can be performed, but optimal conditions cannot be easily determined and machining know-how cannot be shared among workers
Solution Approach 1:
The patent implements a feedback mechanism where actual machining results and optimal cutting conditions are transmitted back to the tool catalog database. When a worker discovers optimal cutting conditions through experimentation, these conditions are automatically recorded in the database, creating a feedback loop that continuously improves the stored information and allows all workers to benefit from accumulated knowledge.
Solution Approach 2:
The patent enables dynamic updates to cutting condition parameters in the tool catalog database based on actual machining performance. Instead of using static catalog examples, the system allows cutting condition parameters to be changed and optimized through practical application, with updated values automatically stored and shared across the network.
3Loss of information
If operators refer to multiple tool catalogs for different tools, then complete tool information can be obtained, but the process becomes time-consuming and burdensome
Solution Approach 1:
The patent creates a universal tool catalog database that serves all numerical controllers and all tool types through a single networked system. This multi-functional database replaces the need for multiple separate catalogs, providing comprehensive tool information access to any controller on the network simultaneously, thereby eliminating time loss while maintaining information completeness.
Data Source
AI summary
In a numerical control system including a numerical controller having a tool database and a tool catalog database which can be referred to from the numerical controller, the tool catalog database has tool catalog data including first cutting condition data, and the tool database has tool data including second cutting condition data to be used for machining. After execution of the machining, the numerical controller updates the first cutting condition data to be stored in the tool catalog database based on the second cutting condition data stored in the tool database.
