CAD/CAM products can be used together as one com- plete solution or as stand-alone programs, either to remove bottlenecks in a current CNC processes or to replace older or obsolete software. It all starts with a high-quality PowerShape CAD for the design of com- plex 3D parts. PowerMill CAM helps create perfect toolpaths first time, every time. The main change in PowerMill’s extensive functionality for five-axis machining has been to increase the number of options for tool-axis definition. For busy production environ- ment, FeatureCAM automates
the creation of reliable NC code for a wide variety of machine tools. PowerInspect offers a comprehensive range of inspec- tion routines for taking simple measurements, for inspection of geometric features and for analyzing complex 3D surfaces. Delcam

Additive Manufacturing Service
Aerospace companies can quickly and accurately test the properties of parts manufactured with high-performance materials such as stainless steel, titanium, cobalt-chrome, and Inconel using Direct Metal Laser Sintering (DMLS) before making a major investment in full-scale production. The work- ing platform for parts is 10 × 10 × 11” (254 × 254 ×279 mm). DMLS parts are built out of lay- ers of metal as thin as 20 µm, making fine details possible.
The process can resolve features down to 0.005" (0.13 mm). Tolerances on features smaller than 1" (25.4 mm) can be as small as ±0.002" (0.05 mm). Surface roughness on parts is approximately 130 µin. RMS. Typical turnaround time is 2–4 business days. In-house material testing for hardness, tensile strength, and elongation are available. For convenience, cus- tomers can upload their files via FineLine’s online quoter. FineLine Prototyping Inc. Ph: 919-272-2479 Web site:

Gantry Mill/Trim Machine The new modular Precision Mill/Trim (PMT) system is a five-axis gantry machine tool for high-speed multiprocessing of large nonferrous components, such as composite struc- tures, aluminum skins and fabrications, molds, patterns, and post-cure cutouts in foam and sandwich structures. In addition to milling, drilling and trimming, the highly configurable PMT is designed to use various special heads, such as waterjet,
finishing tools, and a system for precision control of counter- sink depth. The PMT’s design and capabilities offer shops an affordable, multipurpose platform for fast, accurate large- part finishing processes. The machine’s unlimited X axis is complemented by its configurable Y axis of 2-6 m; Z axis of 1, 1.5 or 2 m; feed rates up to 60 m/min; five-sided part access; and optional precision scale feedback. The compact dual-axis rotary spindle head is powered by direct-drive torque mo- tors with encoder feedback, providing 220° of A-axis tilt and standard 550° of C-axis rotation. The system is available with a Siemens 840sl or Fanuc 31i CNC. Fives Group

High-Speed CNCs
For advanced smooth and accurate simultaneous five-axis high-speed machining, the 30i-B/31i-B5 CNCs feature the High-Speed Smooth TCP with new fairing technology. CNCs drastically reduce cycle times while improving part accuracy and quality. For complex machining, this is the ideal combination of reliability and modern high- speed five-axis features. In addition, Series 30i-Model B controls, which include the
30i-B, 31i-B, 31i-B5, 32i-B and 35i-B CNCs, offer enhanced high-speed and large capacity, multipath PMC with large- scale sequence control with a maximum of five concurrent independent ladders. Execution of common instructions is
