Oxy-Fuel cutting: Automation makes the difference

Abstract

Like laser and water jet cutting, plasma cutting is today a highly automated process. However, the situation is different when it comes to oxyfuel cutting. Over the past few years it has become seemingly less attractive than the other cutting processes, and there is a general reluctance to use it. Could the reason for this be, perhaps, that the process is generally far less likely to be automated? Each cutting method has the application for which it is best suited. Whereas laser is best for thin sheets, water jet is best for special materials where you need to avoid adding heat, and plasma cutting is very good with stainless steel and for small contours. OxyFuel is best suited for cutting carbon steel plate thicker than about 20 mm and for cutting many identical parts. The automation of plasma cutting systems has grown enormously over the last 10 years, mainly due to the innovative approach of the manufacturers of the plasma cutting systems. OxyFuel cutting is by far the oldest cutting method; everyone knows this. However, a lot of training is needed before you can become an oxyfuel cutting expert, and much experience gained over time is necessary to make the perfect cut every time. OxyFuel cutting is in fact perhaps the most sophisticated cutting process. The question is, how can this knowledge be integrated into an automated system? Because automating the cutting process is surely the key to restoring the attractiveness of oxyfuel cutting. Personnel costs will be significantly reduced by adding automation, and it will, at the same time, increase production quality and safety. All these things have a major impact on the overall productivity of the oxyfuel cutting process.
