Laser technology has developed rapidly in recent years and has become a mainstream cutting technology. Because of its superior cutting quality and accuracy, and its unmatched processing speed, the sheet metal industry generally believes that laser cutting will most likely replace punching and become the mainstream sheet metal processing technology in the future.
In addition to two-dimensional cutting, sales of 3-5-axis laser cutting machines have also been very popular in recent years. This is mainly due to the unique advantages of multi-axis machining in terms of performance. For the automotive, aerospace and oil industries, multi-axis laser cutting machines The application is already very common. Unlike two-axis laser cutting, multi-axis machining requires higher processing software.
Plate laser cutting system
Laser cutting is an expensive processing method. In the currently known cutting processing, the laser consumption cost is the highest, and the advantages of laser processing reflect the efficiency and quality, so the improvement of cutting efficiency and product quality is to reduce laser processing. The most cost effective tool. In the actual production process, engineers must strictly control the cutting machine tool's machining process. The key to the process is the material and processing trajectory. In the case of fixed materials, the machining trajectory is the best way to save time and improve efficiency, because the A good program can save processing time and improve the utilization of materials, thereby rapidly reducing costs.
The most important issues in order to get the best program are the following questions:
First, how to use the least amount of material possible without increasing the processing time.
The best way is to identify the actual shape of individual parts using the automatic arbitrary shape nesting function, and arrange these parts as much as possible on the fixed size material. In this way, the high material cost can be saved immediately.
The JETCAM Expert CAD/CAM system, which is commonly used in the sheet metal cutting industry, uses the method of identifying the edge of a part to define parts, and then uses automatic random nesting to automatically fill small areas or irregular parts in some areas. To save material.
Second, how to deal with customers who provide less-than-ideal CAD files DWG, DXF, or IGES files are often transferred from a CAD system. They often find tiny gaps in the intersections and arcs that are too small to be seen with the naked eye. To, or a large number of heavy lines, it is harder for people to notice. This is a very troublesome problem for layouts. The layout requires closed continuous geometry to automatically identify its internal and external contours. At this point, encountering this kind of problem, JETCAM software will automatically "clean up" these files, remove any unpleasant lines, not only without any gaps, but also call "curve-chamfer". Function, a large number of short-term reduction, to produce a relatively short program, reduce the cutting workload of the machine, can get good processing results.
Third, how to reduce the unevenness of the experience of engineers in the programming process JETCAM put forward the concept of “fool†software. The system stores all engineering data in the SEKT system (abbreviation of the Stored Engineering Knowledge Technology). Even if the factory lacks experienced engineers, engineers who are not familiar with the process can call these processes directly to ensure that the output program is optimal.
Multi-axis laser cutting system
The principle of multi-axis cutting and plate cutting is completely different. The first part processed is not directly placed on the machine table, which involves the problem of a workpiece positioning fixture. At this point, PEPS software from Camtek UK is a very simple and practical solution to this problem.
PEPS uses a fixture auto report, first set the reference position for the workpiece to be fixed, determine the range and height to be processed, the system will generate an appropriate spatial grid according to these parameters, generate a solid contour graphic supporting the workpiece, in the determination of a good fixture After the corresponding pitch, the jigs of these entities will automatically generate two-dimensional plane graphics. According to the size of the pre-provided fixture plate, the automatic distribution of good graphics files and NC cutting files is generated.
The second common problem is that multi-axis cutting industry-oriented three-dimensional part design has completely replaced the two-dimensional drawings, customers are provided with a number of three-dimensional parts, and engineers often encounter the problem is that the data through the data conversion is generally distorted Or there are many facets, and the current status of data conversion technology standards determines that this situation is difficult to change.
Moreover, the modification of these three-dimensional graphics also involves non-technical management issues. Usually, it is difficult for customers to accept the need to modify their models, because they fear that these changes will not meet their needs.
PEPS solves this problem by first providing a large number of CAD conversion interfaces. As long as customers use mainstream CAD three-dimensional design software, PEPS can directly convert without converting to a third-party format. These mainstream CAD software includes Pro-E, Catia, Unigraphics, SolidWorks, SolidEdge, Cimatron, Delcam and more. Of course, it is generally accepted that the ParaSolid format has the advantages of stability, small surface area, and little broken surface in terms of three-dimensional conversion. PEPS also provides users with this core technology. Second, PEPS offers quite a lot of adjustments, especially for physical parts. These functions include complete and comprehensive repair functions, surface fitting functions during processing, and fuzzy selection of section curves. These functions also effectively reduce the intensity of the engineer's programming work.
In Asia's emerging industrial countries, although the application of laser cutting is not as widespread as in Europe and the United States, with the global manufacturing shift and laser cutting costs, laser cutting will soon get more applications in these countries.
However, there is a common misconception among customers in Asian countries: emphasis on hardware contempt for software. The purchase of expensive high-end machine tools from Europe, without using any software or purchasing some low-end European and American software, the result is that these machine tools have not been well used, resulting in inefficiency, not worth the candle, especially for high-end laser cutting machine tools, If you do not improve efficiency, the cost can be very expensive.
