In order to achieve the maximum machine performance, Siemens performed a detailed dynamic analysis of the complete machine, control and servodrive system with its Mechatronics service. Data gathered during the Mechatronics process is used to optimize the complete machine concept, allowing the machine builder to push their machine designs to the absolute performance limits with predictable accuracy and part finish results. In highly complex blade contour and finishing op-
erations, the Siemens Sinumerik 840D CNC provides an advanced aerospace-specific software feature, COMPCAD, by which the control’s compressor function smooths point- to-point programming. The real benefit of the control is real- ized when processing the part using NURBS (Non-Rational Uniform B-Splines), which takes the machine to the most advanced level of smooth contouring and chatter elimina- tion. This is achieved by using splines in an axis-specific tolerance window. Contour violations are thus avoided, plus the efficiency of acceleration/decelera- tion curves is increased, while slow- downs/speed-ups at block transitions are eliminated. These are absolutely critical factors in the machining of aerospace surfaces. In programming, according to
Moore engineers, the open architecture of the CNC, along with its high-speed, user-defined macros and flexible block search capabilities, made it an ideal choice for the FSP300X. The ability of the 840D to handle very large pro- grams typical for intricate mold-and-die applications without “drip feed” was also of utmost importance.
Options for heightened aerospace, mold and die, medical and other high- precision uses of this machine include high-frequency spindle options up to 80,000 rpm; a variety of robotic part loaders all designed and built by Moore Tool with all control parameters incor- porated onto the host CNC; a graphite machining package; laser toolsetter with measurement and compensation stan- dards, plus other custom configurations.
Moore Tool further enhances the machine dynamics on its FSP300X by use of Siemens Simodrive 611D drive packages. Other features of the FSP300X include XYZ travels of 420 × 320 × 310 mm, B-axis travel of 230°, infinite C-axis travel, a table load capacity of 25 kg and maximum swing (C-axis ro- tary) of 300 mm. Standard features includes a 10-kW spindle power and 20 m/min contouring federate. The machine deliv- ers geometric straightness on the XYZ axes of 0.005 mm and geometric squareness on the XY/XZ/YZ axes of 0.0076 mm. Moore Tool, which is a member of the PMT Group, de- signs, engineers and builds its machines, in conjunction with sister company, Producto, in a 200,000 ft2
with approximately 200 employees. Moore Tool is a member of The PMT Group. ME For more information from Moore Tool, go to www.moore-
