Hybrid CNC + Additive: Two Heads are Better than One

Hybrid CNC + Additive: Two Heads are Better than One Jason B. Jones Hybrid Manufacturing Technologies Summary Hybrid manufacturing is the combining of additive manufacturing with CNC machining. This presentation defines hybrid manufacturing and talks about the early history of its commercialization, technical advantages and most promising applications. This presentation was delivered at SME's RAPID 2015 Event in Long Beach, CA. Abstract: The combined use of CNC and AM in a single machine has received significant attention since late 2013. Rising awareness of hybrid systems prompts consideration of their potential benefits both in conjunction with and compared to traditional manufacturing. Of particular interest is how much the productivity of AM can be improved without compromising the desired fidelity and surface finish. This presentation highlights the world’s first hybrid machines that can change from high rate to fine metal deposition by tool changing the deposition heads. This gives superior flexibility to achieve optimized cladding for applications ranging from surface coating large areas to detailed build-up of 3D geometry. The capability to change between multiple deposition heads enables a step change improvement to the scaleability of AM. This is analogous to changing milling cutters between roughing and finishing passes during conventional machining to achieve the fastest cycle times without compromising the resulting surface finish. It also sets a new bar for interoperability and paves the way for new products, applications and efficiencies not possible through the use of these technologies independently.
