G83 — Deep Hole Peck Drilling
Feeds to Q depth, fully retracts to R plane to clear chips, returns to just above previous depth, repeats. Use when hole depth exceeds 3× drill diameter. Q = 0.25″ per peck recommended for this diameter.

FAQ

Common Questions

Is my API key safe?
Yes. Your Anthropic API key lives on our server only — it is never sent to your browser, never stored in the HTML file, and never exposed to anyone. All AI calls go from your browser to our server, then from our server to Anthropic. You never see the key after setup.
Does it work on the shop floor on a tablet or phone?
Yes. CNC Expert is a web app — it works in any browser on any device. No installation required. Works on Windows, Mac, iPad, Android tablet, or any smartphone. The layout is responsive and readable on smaller screens.
How accurate is the alarm decoder?
The alarm decoder is powered by Max Meridian's AI engine. For major controls (Fanuc, Haas, Mazak, Siemens) it knows the specific alarm codes, probable causes, and fix procedures with high accuracy. For very rare or obscure machine-specific alarms it may not have complete information, and we always recommend verifying against your machine's official documentation for safety-critical repairs.
Can I use it for our specific machines and materials?
Yes. The control selector at the top lets you specify your exact control (Fanuc 0i, Haas NGC, Mazak, etc.) and the AI tailors every answer to that control — including specific parameter numbers, alarm codes, and button navigation. The feeds & speeds calculator covers 30+ materials including your specific grades like 6061-T6, 4140 pre-hard, Ti-6Al-4V, Inconel 718, and more.
What is the difference between Standard and Premium?
Standard gives you the full AI platform — everything you need day-to-day on the shop floor. Premium adds tools for building and managing institutional knowledge: the Snippet Library (save proven code blocks), Program Builder (assemble programs from snippets), and Training Mode (quiz apprentices and track progress). If you're a programmer or shop lead responsible for training, Premium pays for itself quickly.
Do you offer a free trial of Standard?
Yes — email us at hello@maxmeridianai.com and we'll set you up with a 14-day Standard trial at no cost. No credit card required to start. We want you to see the value before you commit.
