Aerospace Production: Overcoming Challenges in Composite Machining

Composite materials play an important role in aerospace manufacturing. The light weight, durability and ability to create complex shapes from molds make these materials ideal for frames and structural components that enable lighter, more fuel-efficient aircraft.

While composite structures can weigh up to 20 percent less than their metal counterparts, these materials can often be more difficult to machine. The extremely abrasive nature of carbon fiber reinforced polymers (CFRPs) will wear down standard cutting tools more quickly than almost any other material. A standard carbide cutting tool may only hold up to cutting a few feet of CFRPs before its dimensional stability fails, while in traditional metal machining that same tool might last 20 to 50 times that before wearing out.
