Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing methods for managing operating means of machine tools, such as those used in toothed wheel or gear wheel production, lack a centralized evaluation method, leading to restricted access, inefficient data collection over time, and limited exchange between manufacturers.
Innovation Solution
Implementing a data management system that uses transponders, such as RFID tags, integrated with operating means like tools and clamping devices, to enable automated acquisition and evaluation of data during the production process, without manual entries.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Extent of automation
If manual data entry on registration cards is used, then data can be recorded, but data collection is laborious and access is restricted
Solution Approach 1:
The patent replaces manual mechanical data entry systems with automated electronic data acquisition using transponders and read units. Operating means are equipped with transponders that automatically transmit identification and parameter data to read units integrated in the machine tool, eliminating the need for manual registration card entry and enabling automated data collection during machine operation.
Solution Approach 2:
The operating means themselves provide the data through integrated transponders that automatically respond to read units. The system enables self-service data acquisition where the machine tool and its operating means automatically exchange data without requiring external manual intervention, allowing continuous data collection throughout the operational life of the components.
2Loss of information
If centralized data evaluation is implemented, then data exchange between manufacturers improves, but system complexity increases
Solution Approach 1:
The patent implements a universal data management system where transponders and read units can be integrated into various operating means (tools, clamping devices, centring devices) across different machine tools. The standardized transponder system enables consistent data acquisition and exchange between machine manufacturers, tool manufacturers, and toothed wheel producers, creating a multi-functional platform that serves multiple stakeholders without requiring separate systems for each application.
3Manufacturing precision
If operating means are manufactured with maximum precision, then production quality improves, but production costs increase
Solution Approach 1:
The patent implements feedback mechanisms through automated data acquisition and evaluation systems that monitor the condition, usage, and performance of operating means. The evaluation unit analyzes data from transponders to provide feedback on tool wear, service life, and operational parameters, enabling optimized maintenance schedules and precise manufacturing processes that reduce waste and improve efficiency, thereby offsetting the high costs of precision manufacturing.

AI summary
With a method for data management, in particular of operating means of a machine tool, data from operating means (23, 28, 29) of the machine tool (20) is acquired and stored, at least in respect of its identification. According to the invention, this data management takes place with a machine tool (20) for producing toothed wheels or gearwheels and/or the processing of toothed systems, wherein use is made as operating means (23, 28, 29) in particular of dressing and truing tools, clamping means, grinding tools, and/or the like, wherein, for the acquisition in particular of their identification, and preferably of further parameters, such as use data and geometry data, they are in each case equipped with at least one transponder (23′, 28′, 29′). These transponders (23′, 28′, 29′) can communicate with at least one send/read unit (30) assigned to the machine tool (20), for the cableless transfer of data signals. With this data management, the production of precisely manufactured toothed wheels can be achieved, with significantly lower fault quotas and therefore an improved quality standard, and all this with maximum service life times of the processing tools.
