Modern production relies heavily on CNC (Computer Numerical Control) machine tools due to their precision and efficacy in a huge range of applications. A choice of materials in CNC machine tools significantly influences their performance, energy consumption, and machining capabilities. This paper reviews the impact of materials like steel alloys, aluminium alloys, polymer composites, glass ceramics, and tool steels on CNC machining processes. It also explores advancements in CNC technologies, including the adoption of the STEP-NC standard, which enhances flexibility, interoperability, and automation in CNC manufacturing. While these developments promise improvements in efficiency and adaptability, challenges such as standardisation and compatibility remain. The paper emphasises the need for further research and development to optimise material properties, improve energy consumption, and create more flexible CNC control systems. These advancements will contribute to the continued evolution of CNC machining, enabling manufacturers to produce high-quality, cost-effective products with greater precision and sustainability.
