Sometimes the question arises to what extent cryogenic cooling is environmentally-friendly, as the gases used are a consumable, unlike other refrigerants that can be reused. Cryogenic processing does have interesting environmental advantages. The environmental impact of the entire cryogenic cooling process is many times lower than that of conventional cooling.

Cryogenic cooling during machining stands for machining at very low temperatures. This has advantages both for tools made of heat-resistant materials, where the heat can be high during machining, and for the machining of softer materials, which will flow more easily during machining.

Almost 10 years after the introduction of cryogenic machining, a lot of research has been conducted on this technology, its application and pros and cons. However, despite the positive results, the step to the industry does not seem to be so obvious. High time to present this interesting machining method in detail in a short blog series, of which this is the first one.

The future of the machining industry will be digital. A Factory 4.0 has a transparent shop floor and connected machines, as well as other advantages. What exactly does digitisation mean for you as a machining company? And how does it provide solutions for the challenges you are facing today?

Due to developments in data-driven algorithms, more and more AI tools are being developed to process images. Supplying images of tools to AI models can automate this inspection process. The first steps in this direction have been taken in a recent research project.

Various parameters affect the quality of a machining operation. These include the cutting conditions, which in turn depend on other factors. Sometimes cutting conditions are not available from suppliers or adjustments are needed. Standardised techniques exist to take the guesswork out of optimal cutting conditions.

The EMO fair in Hanover took place recently. The theme this year at the machining trade fair was Industry 4.0. Siemens presented their Active Vibration Absorber Unit at EMO Hanover that attenuates vibrations with counter-vibrations.

The EMO fair in Hanover took place recently. The theme this year at the machining trade fair was Industry 4.0. Alicona was showcasing an optical 3D measuring system integrated into a cobot. This allows greater flexibility when measuring products.

Recent research has shown that the use of several sensors is the best way to measure the amount of wear and tear during machining. The combination of different physical parameters seems to say more than a single signal.

Metal working traditionally generates high temperatures so that cooling agents have to be applied. High temperatures increase the wear on tools. Fluids with extremely low temperatures are used with cryogenic machining that results in better productivity and quality.
