Development of a virtual sensor for the comparison of heat partitions in milling under cryogenic cooling lubrication and high-pressure cutting fluid supply

Manufacturing high precision and performance parts in aerospace, automotive medical industries often requires machining of difficult-to-cut materials such as titanium, nickel hardened alloyed steel alloys. Low productivity environmental damage are major problems cutting these materials, which vitally require optimized cooling strategies. High-pressure fluid supply (HP CF) cryogenic lubrication (CRYO CL) two the most effective approaches to increase tool life, avoid scrap production. The scientific knowledge-based application HP CF CRYO CL had a pivotal role improving specifically milling processes. In this context, quantification effect is essential order adapt fluctuating heat generation at zone. novel concept soft sensor for process presented paper. This integrates force measurements transient temperature data from with help mechanical model well an inverse model. These models elevate measured signals flows power thermodynamic domain enabling energy balancing real application. A telemetry system was used measure embedded thermocouples when 42CrMo4 Ti-6Al-4 V ?? ? conditions. way separated versus high-pressure single channel based on carbon dioxide (CO2) oil investigated compared dry various parameters proceeding wear.
