The article discusses the calculation of the cost of laser cutting in the context of optimizing the tool path for CNC laser cutting machines, specifically the ByStar3015 model. The cost of laser cutting is influenced by energy costs, consumption of auxiliary and laser gases, and consumable costs, but not by equipment depreciation or operator and technologist salaries. The study calculates the cost of laser cutting for stainless steel (12Х18Н10Т), aluminum and its alloys (AMz3M), and carbon steel (Ст10кн). It also examines the cost of laser cutting for specific part nesting using standard and special cutting techniques, such as "chained" and "shaking" cutting. The article provides formulas for calculating the cost of laser cutting and the additional cut length when transitioning from one contour to another using special techniques. The results show that applying special cutting methods can reduce the cost of laser cutting by 12-13%. The study also highlights the importance of considering the complexity of the contours when calculating the cost, which can increase the cost by 1.3-2.5 times. The findings are based on practical examples and are supported by detailed calculations and formulas.The article discusses the calculation of the cost of laser cutting in the context of optimizing the tool path for CNC laser cutting machines, specifically the ByStar3015 model.
