Did Cobra Aero skip a step?
The Hillsdale, Michigan, maker of small engines for unmanned aerial systems (drones) routinely uses multiple setups on three-axis machining centers to make intricate parts, such as the one in the adjacent photo. To make these parts more efficiently, the company would be a candidate for five-axis machining. Cobra has considered this, but hasn’t made the move. Yet the company did make a move to a more expensive option for making intricate metal parts: a system for selective laser melting. That is, a metal additive manufacturing machine, in this case from Renishaw.
