Abhisek Das, a customer program manager at Fictiv, has witnessed the implementation and impact of AI in CNC manufacturing. “Specifically, AI co-pilots are being progressively used in computer-aided manufacturing (CAM) programs by machinists and for generative design in computer-aided design (CAD) packages by engineers.”

He points to Autodesk Fusion 360’s Generative Design, a powerful feature within the software that explores design alternatives based on specified constraints and objectives. Another example is CloudNC’s CAM Assist capabilities, which incorporate advanced algorithms and machine learning techniques to enhance the CAM process. It uses AI algorithms to automate and optimize the programming of CNC machine tools and analyzes 3D CAD models to generate efficient toolpaths, considering factors such as cutting forces, material properties, and machine capabilities.

“Innovations like these substantially reduce product development times and costs,” says Das. “They make design iterations shorter and the path to manufacturability smoother. They uncover solutions that may not cross an engineer’s mind, even with a first-principles approach, because the possibilities would literally be endless.”

Materials and Processes in CNC Machining

The future of CNC machining includes cutting-edge developments in materials and hybrid manufacturing processes that are setting new standards, heralding a new era of efficiency and innovation.

Advancement of Materials in CNC Machining: The inclusion of high-performance composites and advanced composite materials is a significant shift in CNC machining. Carbon fiber reinforced polymers (CFRP) and other fiber-reinforced composites are becoming increasingly popular due to their strength, lightness, and durability, making them ideal for demanding applications in aerospace, automotive, and robotics.

Tessa Axsom is the product marketing manager for Fictiv’s CNC machining services. She points out several advancements in CNC machining materials. “Society demands transportation that goes further, faster, and uses less energy,” she explains. “Materials scientists around the world have been tasked with designing or finding new materials that weigh less but are stronger. Superalloys are the sort of designer metal alloys that have improved creep and corrosion/oxidation resistance and have excellent mechanical properties when compared with traditional metal alloys. Superalloys like Hastelloy, Inconel, and A-286 have been increasingly popular in the aerospace, nuclear power, automotive, and chemical processing industries.”

Similar advancements are taking place in the aerospace and aeronautical industries, which have been pressured to remain competitive while reducing carbon emissions. “Superalloy metal matrix composites are basically metal alloys in a fiber matrix that have excellent thermal fatigue and corrosion resistance coupled with high strength. They can withstand high temperatures while staying lower on the density scale, making them perfect for applications like hot-end aerospace parts, naval ship components, and gas turbine engines,” Axsom explains. “However, here we have a situation where a material’s excellent performance properties make it difficult to machine. At high strength at high temperatures, these superalloy metal matrix composites are not good contenders for CNC machining, casting, or forging. So, many utilize them in 3D printing. My guess is that we will continue to see new innovations in materials as the pressure to be the lightest and fastest continues.” 

Additive Manufacturing and CNC Hybrid Systems: This segment has seen remarkable growth with the integration of Laser-Based Additive Manufacturing, Directed Energy Deposition (DED), and Wire Arc Additive Manufacturing (WAAM). These technologies combine the precision of CNC machining with the versatility of additive manufacturing, enabling the creation of complex geometries that were previously unachievable. They offer improved material properties and the potential for significant cost and time savings in the manufacturing process.

Anup Kumar, a manufacturing engineer at Fictiv, is especially enthusiastic about conformal cooling through hybrid systems. “It’s particularly advantageous in the context of injection molding and forging die production,” he points out. It can improve cooling efficiency through intricate channel designs, reduce cycle times, and optimize part quality. This integration offers manufacturers greater design flexibility, material versatility, and cost-effectiveness in producing dies for these critical manufacturing processes.”

He’s also excited about the versatility and efficiency of hybrid systems, which are especially useful for parts repair. This enables manufacturers to quickly and cost-effectively restore damaged or worn-out components to their original functionality. Kumar explains, “By leveraging the strengths of both technologies, hybrid systems provide precise, high-quality repairs that meet the demanding requirements of modern industrial applications.”
