Order-Controlled Remanufacturing of Defective Workpieces
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing manufacturing methods for workpieces result in high costs and material waste due to manual remanufacturing of defective workpieces, which often require unused workpiece blanks and lead to longer manufacturing times and additional material waste.
Innovation Solution
A computer-supported manufacturing method that automatically identifies defective workpieces, reads manufacturing information, and ascertains a suitable workpiece blank for remanufacturing within a planned manufacturing sequence, allowing for automated remanufacturing without manual intervention and minimizing material waste.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If defective workpieces are remanufactured manually by operators using unused workpiece blanks, then defective workpieces can be replaced, but manufacturing costs increase and material waste occurs
Solution Approach 1:
The system recovers unused workpiece blanks that were previously set aside for reserve workpieces and reuses them for remanufacturing defective workpieces. The order control device identifies suitable unused blanks and automatically integrates them into the remanufacturing process, thereby reducing material waste while maintaining workpiece quality
Solution Approach 2:
The manufacturing system performs self-service by automatically detecting defective workpieces, identifying suitable unused blanks, and executing remanufacturing without manual operator intervention. The control device manages the entire remanufacturing workflow autonomously, reducing labor costs and maintaining consistent quality standards
2Productivity
If reserve workpieces are produced in advance to replace defective ones, then production delays are prevented, but manufacturing time increases and material waste occurs
Solution Approach 1:
The system performs preliminary identification and preparation of unused workpiece blanks during the normal manufacturing process. The order control device tracks available blanks in advance, so when a defective workpiece is detected, remanufacturing can immediately begin using pre-identified blanks without causing production delays
Solution Approach 2:
The manufacturing system dynamically adjusts the production plan by automatically integrating remanufacturing tasks into the existing manufacturing sequence. The control device optimizes the timing and allocation of unused blanks based on real-time production status, preventing delays without requiring fixed reserve workpieces
3Reliability
If defective workpieces are remanufactured manually, then workpiece quality can be maintained, but labor costs and manufacturing time increase
Solution Approach 1:
The system replaces manual operator actions with automated control device functions. The control device automatically detects defective workpieces, reads manufacturing information, identifies suitable unused blanks, and executes remanufacturing operations, thereby maintaining quality consistency while significantly improving manufacturing efficiency and reducing labor costs

AI summary
A computer-supported manufacturing method for manufacturing workpieces from a workpiece blank according to a manufacturing plan using a machine tool including a processing device. The method includes manufacturing at least one workpiece using the machine tool. A defective workpiece is identified. Manufacturing information related to the identified defective workpiece is read by an order control device. The method ascertains a workpiece blank which is suitable for remanufacturing the faulty workpiece in a planned manufacturing sequence on the basis of the read manufacturing information by the order control device. The defective workpiece to be remanufactured is arranged on the ascertained workpiece blank by the order control device.
