4dot: Online monitoring of machines
July 15, 2024 / 9:58 AM
4dot is a Czech startup with global ambitions, whose technology for technical diagnostics and process monitoring has already found application in a number of Czech and foreign companies. 4dot specializes in metal forming processes, including metallurgy, and is continuously working on the development and preparation of process monitoring of inserts.
4dot as part of the Digital Factory
4dot will be part of the Digital Factory at this year's MSV. It will showcase its own technologies and the results of current applications.
You will see, for example, the PM3 vibration sensors and the patented SM overmold sensor (strain gauge), developed specifically for forming machines. Furthermore, at the 4dot stand you will find demonstrations of applications on machine tools and forming machines as well as industrial equipment.
Technical diagnostics and process monitoring
Technical diagnostics creates savings in maintenance costs, while process monitoring creates tooling savings, improves quality and automates process control. 4dot soon developed and patented MUSA analyses that can distinguish between signal and noise thanks to simultaneous signal processing, making 4dot technology more sensitive than competing technologies. In engineering diagnostics, MUSA analyses enable both the monitoring of press brake bearings, including clutch bearings where noise is extreme and a sensor cannot be placed directly, and the monitoring of slow movements in linear guides. The most common applications of engineering diagnostics also include monitoring ram clearances and movements during press operation.
The goal of process monitoring is to automate and refine inspection. Its principle is the same for both forming and machining. Process monitoring provides information that cannot be obtained from the machine or by measuring the finished product; it is the real-time behaviour of the tool/product contact itself. In forming, it is possible to obtain information about, for example, the addition of a tool or its release. In machining, it can be used to detect wear or breakage of the insert, which allows immediate reaction to such situations. MUSA analyses make it possible, among other things, to detect damage to multi-cutting tools.
