In highly complex blade contour and finishing operations, the Siemens SINUMERIK 840D CNC provides an advanced aerospace-specific software feature, COMPCAD, by which the control's compressor function smoothes point-to-point programming
. The real benefit of the control is realized 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 elimination.
The EAI middleware market is being driven primarily by the following items: 1) The re-centralization of computing resources, 2) The need to access data from applications running on OS/390, Unix, NT, and Linux platforms, 3) The tremendous effort and expense to accomplish application integration through labor-intensive point-to-point programming
and data migration or conversion methods, and 4) E-business, Internet, and .com paranoia.
