Tere are hundreds of aerospace manufacturing facilities capable of producing quality aerospace parts. However, in order to win new orders they all are looking for an advantage to be cheaper, faster and more accurate. Te drive to reduce aircraſt weight and assembly costs means an increase in part complexity. Te facilities that maximize their equipment’s capabilities will have the edge to win more complex part orders.
Going from dots to curves in aerospace CNC machining.
Side-by-side comparison of traditional (on left) and modern CNC machining.
Almost all modern aerospace parts require four or five-axis motion, and pro-
gramming these complex geometries requires a quality CAD/CAM system. It would be difficult to dissect a typical aerospace part into a sequence of G1, G2, and G3’s without a powerful CAD/CAM system to approximate the surface and generate a toolpath. To take full advantage of the power of today’s modern CNCs, it’s important to understand the basics of what CNCs can do and the changes necessary to push the manufacturing capability of machines to their limits.
