CAM GPT: Part 1 BY STEPHEN LAMARCA TECHNOLOGY ANALYST

Unless you’ve been living under a rock lately, there’s been a ton of hubbub around artificial intelligence (AI), the AI chatbot ChatGPT, and the AI language model GPT4, as well as discussions regarding accessible AIs (read: web-based and open to public use) after recent “hello world” debuts.

machine tool manufacturer (Pocket NC, now Penta

Machine) used clunky software. I don’t want to put the actual company on blast, but they promised their product was the easiest all-in-one CAD/CAM solution ever. Long story short: After seven years in the industry, the polygraph test determined that was a lie. Over the years, I’ve spoken to a ton of software developers and startups dedicated to making the CAM process less aneurysm-inducing. Not much luck. Enter ChatGPT. Lo and behold, after

People use this tech for everything – doing their homework, programming PLCs, writing their wedding vows … My fiancee even used ChatGPT to negotiate a raise via email – and it worked! Some of the buzz is positive, and some is negative – like really negative. When it comes to AI, there will always be detractors who think “Terminator” machines will come for us. As far as I know (at least since starting this project in February), nobody’s attempted to use ChatGPT to program a machine tool, much less arm it with plasma weapons. So, since I hadn’t used ChatGPT yet, I figured: Why not try? (The machine tool part, not the arming it part.) What’s Going On? You see, Millennials like me Google everything. If my car throws a check engine light, I’ll Google the OBDII fault code. If Google says the mass air flow sensor is probably just dirty, I’m going to YouTube to see how to clean it. Sure, everybody does this now, but we were the first, and we’re exceptional at it. Why? Because our teachers told us, “You won’t always have a calculator!” How’d that work out? Not only do I always have a calculator, I can also access almost every piece of music ever created (and its misheard lyrics) in fractions of a second in high fidelity! My point is that no matter where you are, you’ll always have a calculator – and now it can access AI!

just two dialogs with OpenAI’s Chat (that’s what I call it), this image to the right is what I got back. What Kind of Feedback Have You Received? Well, I tell you what, I got a few doubters and a few supporters. But I will say this: Contrary to what some skeptics might think, I’m not going to blindly upload this to

a machine and run it. No machinist worth their salt would do that. Ever. No matter the source of the program. Seriously, have you ever heard a production machine tool operator speak highly of their CAM/manufacturing engineer? They trust them about as far as they can throw them. You sim first; then, if it doesn’t go back to engineering with immediate issues to resolve, you upload it for an “air cut” (no tools, workholding, or stock material). If by some miracle the program makes it that far on the first draft, then the machinist may cut wax to cover their bum and be sure. The planets would have to align for that to happen, though, and I don’t foresee a CAM engineer tearing space-time any time soon. What Can We Expect Next? As I stated above, I’d be dumb to just throw this program into the machine and press play. That’s begging for an “epic machine crash.” Anyway, next step: simulation. A keen eye might see that this program gets bounced faster than a new version of anything by Microsoft needing to be patched. See you next time!

Come Out of the Fever Dream, Please. Sorry. All I’m saying is I think AI is going to be bigger than the

internet. It’s more on the magnitude of discovering fire. Let me show you what I asked ChatGPT. The image to the right was my first interaction with ChatGPT. I nearly teared up. When I started at AMT, one of the first things I attempted was to program our 5-axis CNC (with zero manufacturing background, mind you). Unfortunately, the
