   31. From NC to CNC to AI-NC: The Next Evolution of Manufacturing with Tanmay Aggarwal

   CNC Underground Afterhours pushes past the marketing buzz to take a hard look at AI’s real impact on the machine shop floor. Industry veteran Tanmay, founder and CEO of Lambda Function, joins to discuss AI, automation vs. autonomy, and the relationship between technology and the artistry of CNC machining. Learn why trust is harder to build with AI in manufacturing, what matters most to shop owners, and which tasks AI can and can’t handle today. Understand the future potential for AI-driven CNC, what’s holding back wider adoption, and how knowledge capture is changing the industry. Plus, the conversation takes a thoughtful look at psychology, learning from children, and finding inspiration outside manufacturing. ——— Connect with CNC Underground on LinkedIn: https://www.linkedin.com/company/cnc-underground (https://www.linkedin.com/company/cnc-underground) Connect with Jess on LinkedIn:  https://www.linkedin.com/in/jessicaurbans/ (https://www.linkedin.com/in/jessicaurbans/) Connect with Christina on LinkedIn:  https://www.linkedin.com/in/christinacasanova/ (https://www.linkedin.com/in/christinacasanova/) Connect with Tanmay on LinkedIn: https://www.linkedin.com/in/tanmayaggarwal/ (https://www.linkedin.com/in/tanmayaggarwal/) Connect with Lambda Function on LinkedIn: https://www.linkedin.com/company/lambda-function/ (https://www.linkedin.com/company/lambda-function/) ———Join CNC Underground Newsletter!  https://swiy.co/cncunderground (https://swiy.co/cncunderground) Join CNC Underground — the go-to weekly newsletter read by 6,000+ elite machinists and programmers.

   29. Around the World with Machinist Tony Gunn: Dirty Shops, $20 Wages, and Million-Dollar Anchors

   Tony Gunn shares a unique perspective shaped by decades on the shop floor and years spent visiting hundreds of manufacturing facilities worldwide. This episode covers the real difference between successful and struggling shops, what cleanliness and organization reveal about operations, and how global trends in automation and technology are impacting manufacturing everywhere. The conversation addresses the myths and realities of American manufacturing, including what the U.S. does well, where other countries lead, and how lessons from international shops can inform better practices closer to home. Topics include workforce challenges, how compensation compares to other industries, the critical role of trust in vendor relationships, and practical ways automation can help bridge skills gaps. With stories from visits to shops in Brazil, Germany, Japan, India, Switzerland, and beyond, the episode highlights what each manufacturing culture excels at—from education and automation to precision, respect for the trade, and the willingness to invest in new tech. Listeners also get advice for making the most of trade shows like IMTS and insight into what manufacturing professionals really complain about (and how some of those issues could actually be easier to address than expected). Whether you're a machinist, shop owner, or industry newcomer, this conversation brings honest perspective on where manufacturing stands today and where it's headed. ——— Connect with Jess on LinkedIn:  https://www.linkedin.com/in/jessicaurbans/ (https://www.linkedin.com/in/jessicaurbans/) Connect with Christina on LinkedIn:  https://www.linkedin.com/in/christinacasanova/ (https://www.linkedin.com/in/christinacasanova/) Connect with CNC Underground on LinkedIn: https://www.linkedin.com/company/cnc-underground (https://www.linkedin.com/company/cnc-underground) Connect with CNC Underground on YouTube: https://www.youtube.com/@midwestcamsolutions (https://www.youtube.com/@midwestcamsolutions) Connect with Tony on LinkedIn: https://www.linkedin.com/in/theworldwidemachinist/ (https://www.linkedin.com/in/theworldwidemachinist/) Connect with Tony on Instagram: https://www.instagram.com/therealworldwidemachinist (https://www.instagram.com/therealworldwidemachinist) Connect with Tony on YouTube: https://www.youtube.com/@TheWorldWideMachinist (https://www.youtube.com/@TheWorldWideMachinist) The Machinists Club: https://www.themachinistsclub.com/ (https://www.themachinistsclub.com/) ———Join CNC Underground Newsletter!  https://swiy.co/cncunderground (https://swiy.co/cncunderground) Join CNC Underground — the go-to weekly newsletter read by 6,000+ elite machinists and programmers.
