CNC milling is a subtractive manufacturing process that uses computer-controlled machines to remove material from a workpiece to create complex shapes and features. This method allows for precise control over dimensions and tolerances, resulting in high-quality prototypes that closely resemble the final products. CNC milling machines can operate on various materials, including metals, plastics, composites, and wood, making them versatile tools for numerous applications.
Prototyping is a crucial step in the product development lifecycle. It allows designers and engineers to visualize concepts, assess performance, and identify potential design flaws before mass production. Rapid prototyping, in particular, emphasizes speed and efficiency, enabling teams to iterate quickly based on feedback and testing outcomes. In this context, CNC milling offers a powerful tool to create functional prototypes that accurately represent a product’s design and functionality.
Integrating CNC milling into rapid prototyping processes yields numerous advantages:
