The low price of CNC cutting machine is increasingly subject to relatives in machine tools, engineering machinery, automobiles, ships, locomotives, petroleum machinery, aerospace, textile machinery, grain machines, electrical appliances, elevators, etc. , but in traditional CNC cutting In terms of machine cutting, there are also many problems that need to be improved. It also requires software upgrades for CNC cutting machines, and cutting precision needs to be upgraded and improved to meet the constant demand of the market . CNC cutting machine has gradually replaced the traditional cutting methods in the market, such as wire cutting, copy cutting machine, etc., CNC cutting machine is also because of its simple operation, the following will explain the traditional cutting method and high nesting rate. The difference between cutting methods:
1. High nesting rate cutting method: FastCAM Company advocates and promotes high nesting rate cutting production mode. Using FastCAM optimized nesting software, the whole board nesting and residual material board nesting, and then the whole board cutting and residual material board cutting, effectively avoiding the generation and waste of the residual material of the steel plate, so that the remaining steel plate can be fully reused.
2. Traditional cutting method: reading the DXF or NC file of the part on the CNC system or calling the parts in the CNC system parts library, using the manual or matrix method to carry out nesting and programming on the CNC system, and then on the CNC cutting machine Perform a partial cut. The result of manual nesting and partial cutting is that a large area of ​​irregular steel remains in the middle of the steel sheet, and accurate nesting and cutting can no longer be performed, resulting in a large amount of surplus steel and steel waste.
In the case that the machine tool structure, hardware configuration and manufacturing level of the CNC cutting machine are roughly the same or similar, it is completely possible to achieve " full-time cutting, automatic cutting, software technology, especially the use of FastCAM optimized nesting software and FastCNC numerical control system . efficient cutting, and high-quality cutting nesting cutting rate ", CNC cutting machine further improve cutting efficiency and cutting quality, and saving steel consumables.
In short, when choosing the nesting software, we must look for the brand quality, combined with numerical control equipment, and comprehensively improve the production quality. The operator should learn the specific operation content of the nesting software and use the equipment effectively.
