Delcam to Support DMG/Mori Seiki Innovation Day
Delcam is supporting the DMG/Mori Seiki Innovation Days to be held at the companies’ new joint North American headquarters in Hoffman Estates, Illinois, from 24th to 26th May. 29 live machining demonstrations will be featured at the event to showcase the broad range of equipment on offer from the two companies. Full details can be found on http://www.idays2010.com.
One of the novel techniques to be demonstrated will be pinch milling, a method for machining long, slender components, such as propellers or turbine blades. This uses milling cutters in both the upper and lower spindle heads to machine the opposite sides of the part at the same time. The toolpaths for the two cutting tools are programmed in Delcam’s PowerMILL CAM system so that the forces they put on the part are in balance. This gives greater accuracy by reducing the tendency of the component to bend away from the required alignment.
Pinch milling results in two significant opportunities to improve the overall manufacturing time. Of course, the ability to cut with two tools simultaneously means that machining times will be reduced. For example, it might be possible to run a semi-finishing toolpath with one tool and a finishing toolpath with a second tool at the same time. Furthermore, because the forces applied by the two cutters are in opposition, the depth of cut, or the feed rate, can be increased for both operations, without excessive deflection of the part.
Another part to be programmed with PowerMILL will be a titanium knee joint. This will be machined on the Mori Seiki NMV 3000 five-axis machine. It will provide a great example of the power and flexibility of the five-axis strategies in PowerMILL.
The choice of a medical part is also very timely as Delcam is currently seeing strong demand for its software from the healthcare industry. The companies are experiencing the same pressures from their customers for faster delivery and reduced costs that have persuaded large numbers of engineering firms to switch to Delcam software.
Other highlights of the Innovation Days will be the chance to win tickets for the Indianapolis 500 as guests of Andretti Autosport, and presentations by Douglas Woods, President on the Association of Manufacturing Technology, and William A. Strauss, Senior Economist at the Federal Reserve Bank of Chicago, on the state of North American manufacturing economy.
