Complex geometries and workpieces from a wide variety of metals can be created with DMG Mori s Lasertec 65 AdditiveManufacturing machine using generative laser deposition welding and five-axis milling. Additive Joins Subtractive on Advanced All-in-One Machines New levels of hybrid multifunction machines are here, as five-axis milling mixes with laser deposition welding technologies Jim Lorincz Senior Editor The path of precision machining has taken a decidedly unexpected change in direction. Yes, machining centers, in their various configurations of horizontal, vertical, and universal, continue to hold their preeminent positions in shops for their ability to create value-added benefits to individual workpieces or parts in serial production. The future appears bright for continuing advances in spindles that offer high-speed and high-torque performance in production situations, especially in the automotive industry and continuing expansion of multifunction capability for example in gear making, and merging of milling and turning capabilities onto one machine.

But the distinctions between stand-alone machining centers continue to be driven by the addition of multifunction capabilities leading to multitasking magic five-axis versatility, and altogether new iterations like additive/subtractive machine combinations. The newest advanced machines can bridge the gap between highly complex designs with laser-sintered metal welding deposition and removal of metal through subtractive milling processes. We see a tremendous emphasis on five-axis machining whether mill-turn or turn-mill machines, said Randy Harland, executive vice president, DMG MORI USA (Hoffman Estates, IL). Customers have known for a while that when machining on a lathe it s generally best to be able to finish machining operations with milling on the same machine. Now the ability to put the workpiece on a machining center and articulate the workpiece or the head in virtually any direction and do practically any secondary operation on the machine is equally important, particularly turning. HAIMER Power Series: Rock solid and highest precision The best on this planet. Tooling Technology Shrinking Technology Balancing Technology Haimer USA, LLC 134 E. Hill Street IL 60181 Villa Park Phone: +1-630-833-1500 E-Mail: haimer@haimer-usa.com www.haimer-usa.com Measuring Instruments We re seeing a change in terms of recognition by US machine tool consumers to embrace what the Europeans have been doing for a long time. We have a lot of models that we re having success with, including the DMU and DMC monoblock and duoblock machines, and the evolution series. One of the most compelling models for us is the DMU 50 five-axis machining center that is excellent for first time five-axis users who are interested in the power and speed of a Siemens or Heidenhain control and shops that would ordinarily be buying vertical machining centers, said Harland. DMG MORI will begin manufacturing this German-designed product at its Davis, CA, manufacturing facility later this year. Automotive, Multifunction Loom Large in Plans DMG MORI USA is creating a Center of Excellence for Automotive in Novi, MI, which will be a showcase for machine technology that has been so successful in automotive manufacturing in Japan. We are bound and determined that the US producers of those same kinds of automotive workpieces understand how we have processed them so successfully in Japan for so long. We will be demonstrating those processes and will deploy some of the machines that we will exhibit at IMTS at the Center, said Harland. Multifunctionality continues to be the newest driver of machine design at DMG MORI. At our 2014 Innovation Days in Chicago, many of the 40 machines that will be shown will have gearmaking capability using our software called gearmill, which can be used on many of our products, said Harland. Taking multifunctionality to another level, DMG MORI has merged toolchangeable additive manufacturing onto standard-offering subtractive five-axis milling platforms. The first concept study multifunction machine is called LASERTEC 65 AdditiveManufacturing. This hybrid machine incorporates generative laser deposition sintering on a five-axis milling machine, enabling complex metal geometries and workpieces 68 ManufacturingEngineeringMedia.com April 2014

to be produced with combined laser deposition sintering and five-axis milling. With the LASERTEC 65 AdditiveManufacturing, we have added laser sintering capability to alternately build up and mill powder metal using a wide variety of metals. The method uses a deposition process by means of a powder nozzle which is up to 20 times faster than generation in a powder bed, said Harland. Equipped with a 2-kW diode laser, the LASERTEC 65 AdditiveManufacturing is expected to expand the market for additive processes from metal prototype and small part production to complete machining of complex components with undercuts as well as for repair work. The LASERTEC 65 AdditiveManufacturing is also well-suited for application of partial or complete coatings for mold making and general engineering or medical applications. Changeover between milling and laser sintering operations on the LASER- TEC 65 AdditiveManufacturing is automatic with the option to successively build up layers of different materials in wall thicknesses of 0.1 5 mm. Complex 3D contours can also be generated in layers without supports, or large workpieces can be rough and finish machined and coated with corrosion-resistant alloys for applications in the energy and oil industry. EDM Cell with Precision Machining, Automation Roku-Roku vertical machining centers are well known to be built to jig-bore standards. Precision machining of graphite and hard milling applications results from careful thermal control and compensation for all machining axes, said Len De Bruyne, application engineer-machining centers and cells, MC Machinery Systems (Wood Dale, IL). The ability of the machine to produce an accurate part, especially for such high-dollar parts as medical and aerospace applications is essential, said De Bruyne. These machines are put into service to run non-stop with integrated robots in automated cells. For example, we have created special automated systems to increase the throughput for EDM operations. The cell design today build tomorrow Unlock the potential of Additive Manufacturing Renishaw s laser melting system is a pioneering process capable of producing fully dense metal parts direct from 3D CAD. From tooling inserts featuring conformal cooling, to lightweight structures for aerospace and high technology applications, laser melting gives designers more freedom, resulting in structures and shapes that would otherwise be constrained by conventional processes or the tooling requirements of volume production. It is also complementary to conventional machining technologies, and directly contributes to reduced lead times, tooling costs and material waste. Shorten development time be first to market Reduce waste and cost build only what you need Increase design freedom create complex structures and hidden features See us at Renishaw Inc Hoffman Estates, IL www.renishaw.com/additive BOOTH #1215 April 2014 ManufacturingEngineeringMedia.com 69

For automating EDM operations, MC Machinery integrates a Roku-Roku H658 VMC for machining graphite electrodes and a 3R pallet system for storing and loading them on a Mitsubishi EA12E sinker EDM in a cell. (also available in sk/bt 50 taper), a 500 630-mm pallet, and 800-mm strokes in X, Y, Z axes. Introduced at EMO 2013, the H 4500 is designed for robust processes while providing an affordable, economical cutting solution for limited floor space and energy efficiency. Machines are capable of energy savings of up to 30% compared to conventional machine designs. Metal-cutting performance has been enhanced with the introduction of the new powerful spindle. With our new 500-Nm, 52-kW, 12,500-rpm spindle option, the H4500 can provide the low-speed torque it takes for cutting tough materials like iron and steel as well as higher speeds for machining lighter alloys, said Vincent Trampus, Heller vice president sales. This capability sets Heller apart from others in its size range. The more universal and varied the machining assignment, the more important becomes adaptive power consumption of peripheral equipment and main units in order to optimize power use at various operating points, said Trampus. Air, coolant, hydraulics, and other energy consumers are flexibly controlled based on demand rather than always beong on. Precision machining of graphite and hard-milling applications result from careful thermal control and compensation for all machining axes. The H 4500 offers a wide range of basic equipment, so each machine can be customized for each user s 74 ManufacturingEngineeringMedia.com April 2014
