Lights Out Isn't the Future—It's Already Here, 513

Automation and lights-out manufacturing are often framed as the future of machining, but for many shops that future is already here. In this episode of MakingChips, we sit down with longtime industry leader Keith Grano to talk about what lights-out machining actually looks like in practice. Drawing on years of experience working with manufacturers, Keith explains how automation, machine monitoring, and disciplined processes allow shops to run more efficiently and extend production beyond the traditional workday. Lights-out machining isn't about replacing people. It's about using technology to make better use of the time, talent, and equipment already inside a shop. When done well, it increases capacity, improves consistency, and helps manufacturers grow even when skilled labor is limited. Keith walks through the practical considerations behind unattended production, including machine reliability, process stability, tooling strategy, and the systems required to keep parts running when no one is standing at the control. Along the way, we explore why many shops struggle to implement automation and why incremental steps often work better than trying to jump straight into fully autonomous production. This conversation also connects to a theme we've been exploring across our Generation CNC series: the next generation of manufacturing leaders is entering an industry where automation and digital systems are becoming foundational capabilities. Understanding how lights-out machining works, and when it makes sense, will shape how the next generation builds and scales their shops.
