A lights-out cell is only as reliable as its weakest tool. Here’s a practical checklist for choosing, setting up and managing tooling so your machines keep making good parts after everyone has gone home.

IMTS 2026 showed AI that writes toolpaths, picks strategies and fills the gap left by retiring programmers. But every one of those systems depends on accurate tool data. If the data going in is poor, the toolpaths coming out will be too, only faster.

AMB 2026 launched its first defense program. At IMTS, new additive systems were pitched to defense buyers who want shorter supply chains. Defense has become a show category of its own, and that raises the bar for every shop that machines A&D parts.
