There are many factors in the MLS system that can achieve such high productivity. Of course, the mechanical properties and specifications are very important, for example, the rapid feed rate is 60m/min and the acceleration is 8m/s2. The purpose is to achieve higher production efficiency, not to make the machine have faster characteristics. . According to Mr. Bernd Zapf and his colleagues (the development team consisting of 40 people) who are responsible for the development of this machine tool system, they can increase productivity by another 1% to 2% if they further improve the performance of each axis. If they can reduce the idle time of the machine by speeding up tool change and chip-to-chip time, productivity can be increased by about 6%. To this end, they are working hard to solve the problem of how to further reduce tool change time. Essentially, the magazine installation location is generally above the spindle. The next tool to be used is pre-positioned on the tool changer, so the "knife-to-tool" time is close to "zero", while the chip-to-chip time is only 2.4s. In the case of frequent tool changes, this The accumulation of a number is also considerable, and it usually plays an important role in the processing of powertrain components such as cylinders, cabinets and gearboxes. The same is true for the parts changer. When one part is machined, another part to be machined is waiting outside the processing area, so the replacement time of the workpiece is only 10s or less.
Figure 3: The tool changer of the MLS system requires the tool to be adjusted before replacement, which minimizes chip-to-chip time.
Conclusion
So it can be said that the MLS system is built using multiple machine tools. Parts can be machined in series or in parallel, and in some cases mixed. Completely different types of parts can be machined at the same time. When the product or production changes, the user can also increase the number of machine tools or reduce the number of machine tools in a relatively straightforward form. In general, an MLS system can focus on how to minimize total asset costs, just like a flexible production system based on a machining center.
Cimatron Germany will sell GibbsCAM software and provide technical support
Israel's Cimatron has announced that its branch in Germany has started selling advanced GibbsCAM processing software solutions and providing technical support in Germany under the name Virtual Gibbs.
It is reported that after the merger of Cimatron and Gibbs in the United States at the beginning of this year, the German branch is the last company to provide GibbsCAM software solutions among Cimatron's many subsidiaries. With offices in Ettlingen, Hamm, Ismaning, Cologn and Nuremberg, Cimatron has a strong customer base and has served thousands of German toolmakers and process manufacturers for more than a decade.
GibbsCAM software solutions offer a wide range of CNC programming functions for machining, turning, turning and milling, rotary milling, tombstone machining systems, wire cutting and multi-turret/multi-spindle machines (multi-tasking machines). Model functional tuning to support the creation and operation of wireframes, surfaces, and solids.
GibbsCAM software features an intuitive user interface with built-in integration and simulation capabilities that enable manufacturers to increase productivity, increase responsiveness to customer requirements, and change designs in a timely manner. The software supports controllers and machine tools from advanced suppliers including GE Fanuc, Infimatic, Siemens, Doosan Infracore, Haas, Index, MAG Fadal, Matsuura, Mazak, Mitsubishi, Mori Seiki, Nakamura Tome and Tornos.
Robb Weinstein, senior vice president of sales and strategic planning at Gibbs, said that the integration of Cimatron's resources and information provides a fast and reliable channel for expanding GibbsCAM's global distribution network.
Cimatron will work with GibbsCAM's distributors in Germany to take advantage of potential synergies.
Dirk Dombert, General Manager of Cimatron GmbH, said: "GibbsCAM software enables us to better respond to the needs of manufacturing solutions in the German market. We look forward to providing this highly reputable solution to complement the rest of the Cimatron software package. â€
