JULY 2018 Additive Manufacturing IMTS 2018 ON DISPLAY 42 Organized by AMT—The Association For Manufacturing Technology, the International Manufacturing Technology Show (IMTS) 2018 takes place September 10-15 at McCormick Place in Chicago, Illinois. The following section previews some of the AM equipment that will be on display, both in the Additive Manufacturing Pavilion, located at the entrance to the West Building, and elsewhere on the show floor. Industrial-Scale 3D Printer Facilitates Cost-Effective Production EOS North America's EOS P 500 3D printer is intended for laser sintering applications on an industrial scale. The printer is designed to produce high-quality, cost-effective polymer parts. Its software tools are intended for ease of use. The machine offers materials flexibility with operating temperatures as high as 300°C. Its modular design enables integration with future machine adaptions. EOS North America | West, Level 3, Booth 432007 Simulation Software Verifies Additive Build Process Version 8.2 of CGTech's Vericut optimization and veri- fication software simulates an expansive range of CNC machine types and manufacturing operations, including additive and hybrid manufacturing, in addition to drilling and trimming, waterjet machining, riveting, and milling and turning. It can simulate robots and parallel kinematic/hexa- pods as well. The program operates independently but can also be integrated with CAM systems. According to the developer, Vericut software adds realism to additive manufacturing simulations to improve verification of additive build processes. These processes include the buildup of overlaps, acute corners, tight over- lapping bead paths and double deposits (overlapping start/ end points). An alert message will appear when the laser focal point is too far from the part's surface, when there are excessive overhang conditions or when there is too much build up at corners and overlaps. During simulations, the software detects collisions and near-misses between all machine tool components and user-defined objects. Users can also set up "near-miss zones" around the components to detect over-travel errors. In Review Mode, the software can simulate machine move- ments while stepping or playing backwards. A customizable heads-up display (HUD) shows the NC program or status item on top of Views. The HUD moni- tors the NC program and machine functions while keeping simulation Views as large as possible. Program Alerts highlights errors and warnings, and, when running multi- ple NC programs, it highlights programs with errors in red. The Force physics-based NC program module analyzes and optimizes cutting conditions throughout CNC program operations. Force is available for turning and milling machines. Force Turning facilitates changing and limiting chip thickness and feed rates while cutting in corners, di- ameters and tight spaces. Force Calibration creates Force Material Files from dynamometer test data. It includes a Design of Experiment (DOE) planner, validates data and shows statistics. CGTech | East, Level 3, Booth 133346
