What is Challenges and Considerations in CNC Machining’s Future

Aluminum or Steel Injection Mold

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 XTJ’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 XTJ, 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.”


Sustainability is becoming a cornerstone in CNC machining as the industry shifts toward more eco-friendly practices. Let’s look at some of the latest sustainable initiatives and technologies.

Energy Efficiency in CNC Machines: Advanced motor technologies are being implemented for greater efficiency, while regenerative braking systems capture and reuse energy. Intelligent power management systems optimize energy use, reducing overall consumption and operational costs.

Waste Reduction and Recycling Initiatives: The industry is focusing on refining machining processes to reduce material wastage. Scrap material recycling is being prioritized, supporting circular economy practices and contributing to more sustainable production cycles.

Sustainable Materials and Practices: The shift to eco-friendly cutting fluids reduces environmental impact. Selection of sustainable materials for manufacturing and compliance with environmental certification standards are becoming increasingly important, reflecting the industry’s commitment to sustainable practices.

XTJ’s Ashwin Kasirajan is a manufacturing engineer who notes that minimizing the usage and responsible disposal of coolant, as well as alternative and renewable energy implementations. “There are many advantages to implementing sustainable practices in CNC machining,” he explains. “Beyond the reduced environmental impact and regulatory requirements, these initiatives can help lower operating costs over time and enhance the company’s reputation with customers, investors, and other stakeholders.”



In this section, we address the key challenges and considerations that are shaping the future of CNC machining:

Cybersecurity Concerns: The integration of CNC machines into digital networks raises concerns about data security, necessitating robust protective measures against cyber threats. Network vulnerabilities must be addressed to prevent unauthorized access and safeguard sensitive information. Additionally, protecting intellectual property in a digital landscape is vital to maintaining competitive advantages and industry integrity.

Skilled Workforce Shortages: The increasing technological complexity of CNC systems requires a workforce with specialized skills. This challenge is compounded by an aging workforce, emphasizing the need for targeted training and education programs to prepare a new generation of skilled workers.

Regulatory Compliance and Standards: Navigating the evolving landscape of quality standards, environmental regulations, and international guidelines is crucial. Adherence to these standards ensures product quality, environmental responsibility, and the ability to compete in global markets, making compliance a key factor in the industry’s future.

Each aspect presents unique challenges but also opportunities for innovation and advancement in CNC machining.

Let’s take a look at the impact of broader industry and economic trends on the future of CNC machining:

Growth Projections for the CNC Machining Industry: Anticipated continuous growth is driven by the industry’s eagerness to adopt cutting-edge technologies, enhancing efficiency and capabilities.
