Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In high-volume production using CNC machine tools, existing machining commands are not easily updated to reflect new machining technique information, as this requires returning to the CAM system for recalculation, making the process complex and inefficient.
Innovation Solution
A machining command improving system that connects CNC machine tools with a shared database, allowing machining state recording and method improvement units to associate and register machining technique information, enabling the updating of machining commands without returning to the CAM system, thus simplifying the improvement process.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If machining commands are updated by returning to the CAM system for recalculation, then machining technique information can be reflected in the machining command, but the process becomes complex and time-consuming
Solution Approach 1:
The patent extracts the machining command improvement function from the upstream CAM system and relocates it to the downstream CNC machine tool. The CNC machine tool now independently performs command improvement by selecting appropriate machining technique information from a database, eliminating the need to return to CAM for updates.
Solution Approach 2:
The patent introduces a machining technique information database as an intermediary between the CAM system and CNC machine tool. This database stores and manages machining technique information, allowing the CNC machine tool to access and apply improved techniques without direct CAM intervention.
2Reliability
If machining commands are updated by returning to the CAM system, then new machining technique information can be incorporated, but the update process requires advanced CAM skills and is inaccessible to operators
Solution Approach 1:
The patent enables the CNC machine tool to perform self-improvement of machining commands by autonomously selecting and applying machining technique information from the database. Operators can initiate improvements without requiring advanced CAM skills, as the system handles the complex selection and application processes automatically.
Solution Approach 2:
The patent performs preliminary organization and storage of machining technique information in a structured database during the CAM phase. This pre-processing allows the CNC machine tool to easily access and apply appropriate techniques during operation, simplifying the update process for end-users.
3Productivity
If machining commands are not updated after high-volume production starts, then production stability is maintained, but accumulated machining technique information is not reflected in existing commands
Solution Approach 1:
The patent transforms the static machining command into a dynamic, updatable instruction set. The CNC machine tool can now adaptively improve commands during production by incorporating accumulated machining technique information, allowing both production stability and continuous improvement to coexist.
Solution Approach 2:
The patent establishes a feedback mechanism where machining technique information accumulated during production is systematically captured, stored in a database, and fed back into the command improvement process. This closed-loop system ensures that valuable operational experience continuously enhances machining commands without disrupting production stability.

AI summary
A machining command improving system is in an integrated system in which a CNC machine tool for machining of a machining target into a predetermined machining geometry a machining command and a shared database are connected to each other. The machining command improving system includes: a machining state recording unit that associates requested information indicating a request to be satisfied in the machining when the CNC machine tool performs the machining and state information indicating a state of implementation of the machining, and registers the associated requested information and state information as machining technique information; and a machining method improving unit. The machining method improving unit improves the machining command of the improvement target at the CNC machine tool based on machining technique information registered with the shared database and including requested information conforming at least partially to requested information corresponding to a machining command of an improvement target.
