Workpiece ID Traceability Across Multi-Module Machine Tools
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing machine tool systems lack traceability for series of manufacturing operations performed across multiple work machine modules, which is essential for tracking workpiece history and quality control.
Innovation Solution
A machine tool apparatus comprising multiple work machine modules, a robot for conveying workpieces, an individual information-providing device for assigning unique IDs, and a control device that links and stores manufacturing histories for each workpiece, enabling traceability across all modules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If traceability is provided for a single manufacturing device using workpiece ID, then traceability for that specific device is achieved, but traceability for series of manufacturing operations across multiple work machine modules cannot be provided
Solution Approach 1:
The control device is designed to perform multiple functions: it not only provides workpiece IDs but also collects manufacturing history data from multiple work machine modules and links this data to the workpiece ID. This universal approach enables the same control device to handle both identification and comprehensive traceability across multiple modules, resolving the contradiction between single-device traceability and multi-module traceability capability
2Productivity
If multiple work machine modules perform series of manufacturing operations, then productivity is improved, but traceability of the series of manufacturing operations cannot be provided
Solution Approach 1:
The control device acts as an intermediary between multiple work machine modules and the manufacturing history database. It collects manufacturing history data from each module, links this data to the workpiece ID, and stores it in a unified manner. This intermediary function ensures that as productivity increases through multiple modules, traceability information is not lost but systematically accumulated and preserved
3Measurement precision
If workpiece ID is provided by individual information-providing device, then individual identification is achieved, but linking of manufacturing history data across multiple modules is not achieved
Solution Approach 1:
The control device merges the workpiece identification function with the manufacturing history collection and linkage function. Instead of having separate systems for ID provision and history tracking, the control device combines these functions, using the workpiece ID as a unified key to link manufacturing history data from multiple work machine modules, thereby preventing information loss and ensuring complete traceability

AI summary
The machine tool apparatus comprises: multiple work machine modules configured to sequentially perform a series of manufacturing-related operations on a workpiece; a robot configured to convey the workpiece between the multiple work machine modules; an individual information-providing device configured to provide an individual information to the workpiece conveyed into the multiple work machine modules and subjected to manufacturing-related operations; a storage device; and a control device configured to link the manufacturing history of manufacturing-related operations performed on the workpiece by the multiple work machine modules and store the information in the storage section, the workpiece being a workpiece to which the individual information was provided by the individual information-providing device.
