Effectively save steel and consumables from the nesting production level <br> Currently, many companies use CNC cutting machines, including the use of FastCAM nesting software, to achieve simple cutting. However, steel utilization is not high. For example, in the flame cutting machine, each part is preheated and perforated, cutting it individually, leaving a large slicing distance between parts, cutting efficiency is low, and steel waste is large. In general, cutting carbon steel 10 ~ 20mm thick, flame cutting efficiency is only equivalent to a quarter of the plasma cutting efficiency, that is, the efficiency of a CNC plasma cutting machine can replace the cutting efficiency of the four flame cutting machine, of course, If you cut a thick plate more than 20mm, plasma cutting machine has no advantage of flame cutting machine. The use of CNC plasma cutting machine, high cutting efficiency, good quality, but the high cost of plasma procurement, the use of plasma torch electrode cost is higher, the average wear a hole to pay more than the flame cutting 10 to 20 yuan cost, a plasma cutting machine The loss of one month's torch electrode is 1 to 20,000 yuan.
The new FastCAM nesting software now offers a new automatic co-edge nesting and bridge continuous cutting technology. The full-automatic co-edge nesting can achieve the common edges of the straight edges of different parts. The four edges of the rectangular parts are all co-edge. The parts after the co-edge only need to cut three edges or two edges. Therefore, the common edge cutting path can reduce 25 More than %, the spacing between parts is reduced, which effectively improves the utilization of steel nesting materials.
The results of more than six months, dozens of users of the cutting test, cutting quality and save steel effect is very obvious. On average, with co-edge nesting, steel nesting utilization can be increased by 3 to 5%. Especially for flame cutting, due to the large spacing of plate thickness parts, the utilization rate of co-edge nesting materials is usually increased by more than 5%. Another major advantage of co-edge nesting cutting technology for flame and plasma cutting is to reduce and avoid preheating and perforation by more than 70%, effectively improving cutting efficiency. For plasma cutting, the biggest problem for companies is that the plasma cutting nozzle electrode is too much. The above mentioned plasma cutting machine has an average one-year cutting electrode electrode loss of up to 200,000 yuan. If there are several plasma cutting machines, then There are millions of cutting electrode costs in a year. Therefore, the plasma cutting machine uses the co-edge nesting technology and adopts borrowing to start arcs to avoid direct perforation and effectively save cutting electrode. For anisotropic parts that cannot use co-edge materials, use bridging or continuous cutting technology to achieve continuous cutting of the parts into pieces. It can also avoid perforation, effectively reduce and avoid perforation by 70%, thus effectively reducing the plasma cutting tip electrode, etc. Consumables consume 40%. For laser and waterjet cutting, the co-edge bridging and cutting material cutting technology can also reduce the number of perforations, reduce the loss of laser lenses or waterjet consumables, improve the laser and waterjet cutting efficiency, and improve steel utilization.
FastCAM proposes a comprehensive solution to save steel from three levels. First, from the production level of nesting, FastCAM uses a fully automated co-edge bridging and cutting kit to improve cutting efficiency and steel nesting efficiency to save steel. From the aspect of management and reuse of surplus steel, FastTRACK residual material database management software was used to make surplus steels effectively managed and reused, effectively improving the utilization rate of the remaining steel products; thirdly, from the steel budget procurement warehousing management and information management level, The use of steel cutting cutting material FastMES agile manufacturing execution system, to achieve the information management of steel cutting and cutting production process, and ERP system to build enterprise information platform.
