Gasno rezanje - automatizacija čini razliku
Oxy-Fuel cutting: Automation makes the difference
Sažetak
Kao i lasersko i vodeno rezanje, rezanje plazmom je danas visoko automatizovan process. Međutim, situacija je drugačija kada se radi o gasnom rezanju. Tokom proteklih nekoliko godina ono je postalo naizgled manje atraktivno od ostalih procesa rezanja i postoji opšta nevoljnost da se ono koristi. Da li je možda razlog za to možda da je proces uopšteno daleko manje automatizovan? Svaka metoda rezanja ima primenu za koju je najprikladnija. Dok je laser najbolji za tanke limove, vodeni mlaz je najbolji za specijalne materijale, gde treba izbegavati dodavanje toplote a rezanje plazmom je veoma dobro za nerđajuće čelike i za male konture. Gasno je najpogodnije za rezanje ploča od ugljeničnog čelika deblje od oko 20mm i za sečenje mnogih identičnih delova Automatizacija sistema za rezanje plazmom je ogromno porasla u poslednjih 10 godina, uglavnom zahvaljujući inovativnom pristupu proizvođača sistema za rezanje plazmom Rezanje kiseonikom je daleko najstariji metod rezanja; svi to znaju. Međutim, potrebno je mnogo treninga pre nego što postanete stručnjak za gasno rezanje i potrebno je mnogo iskustva stečenog tokom vremena da bi svaki put napravili savršen rez. Rezanje kiseonikom je možda najsofisticiraniji proces rezanja. Pitanje je kako se to znanje može integrisati u automatski sistem? Zato što je automatizacija procesa rezanja svakako ključ za vraćanje atraktivnosti gasnog rezanja. Troškovi osoblja biće značajno smanjeni dodavanjem automatizacije i istovremeno će povećati kvalitet i sigurnost proizvodnje. Sve ove stvari imaju veliki uticaj na ukupnu produktivnost procesa gasnog rezanja.
Abstract
Like laser and water jet cutting, plasma cutting is today a highly automated process. However, the situation is different when it comes to Oxy-Fuel 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. Oxy-Fuel is best suited for cutting carbon steel plate thicker than about 20mm 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. Oxy-Fuel cutting is by far the oldest cutting method; everyone knows this. However, a lot of training is needed before you can become an Oxy-Fuel cutting expert and much experience gained over time is necessary to make the perfect cut every time. Oxy-Fuel 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 restore the attractiveness of Oxy-Fuel 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 overall productivity of the Oxy-Fuel cutting process.
