The machine builder turned to its longtime business partner, Siemens, for assistance. Both high-speed roughing and then very precise 5-axis machining were required in this small footprint machine, which had been selected by the customer due to specific plant capacity utilization concerns, plus their desire for a flexible, reasonably priced and highly cost-effective machine tool. The customer, a major upstream oil industry supplier, was trying to decide if the better path for this product was a single block of steel or a near net casting being machined. The customer further presented the builder with the need for fast changeover to produce the part from various metal materials, with all the attendant tool changes and workpiece setup variances present. On one recent application, DMG MORI was challenged with a 440-pound, 8” diameter x 8” high workpiece made from 1045 grade steel and being machined into a rock bit for oil field exploration. “It is a David handles Goliath type of story,” says Matthias Leinberger, the business development director for Siemens PLM (Product Lifecycle Management). The DMU 50, although an entry-level 5-axis machining center from DMG MORI, is a compact unit that features considerable strength, as the following example will detail. Typically, components produced for the oil-and-gas field are very large, very heavy and often have complex contours, making the machining time long and the tool life short. Inherent in this market are several factors that lobby for great care and planning in the machining process.

Please visit the NX Manufacturing community to learn more about What’s New in NX for Manufacturing. NX is part of the Xcelerator portfolio, Siemens’ integrated portfolio of software, services and application development platform. Fully integrated in NX CAM and with more than 1,000 postprocessors, Post Hub can help manufacturers generate programs for a wide range of CNC machine and control configurations. Post Hub is a new, cloud-based solution for post-processing that enables a streamlined process to generate production-ready CNC programs. It supports the HP MJF 5200 and HP MJF 540 color series. The new Siemens HP MJF Build Processor enables printing of color parts directly out of NX, without the need for third-party build processors. NX Additive Manufacturing facilitates the process from design model to printed part with integration that eliminates the need to convert and remodel parts between applications. NX CAM software’s new 5-Axis Adaptive Milling, an advanced roughing strategy, enables high material removal rates using fewer setups resulting in shorter machining times. 5-Axis Guiding Curves finishing has been enhanced to include parametric tool-axis interpolation, providing more control for surface finish. Robotic programming now enables users to program and simulate multiple robots to perform machining tasks such as drilling, deburring and polishing. The software can accelerate machining, program multiple robots, print color parts and generate production-ready CNC programs using a cloud-based technology. Siemens Digital Industries Software makes available the release of Siemens’ NX for manufacturing software, an end-to-end solution for part manufacturing.
