Interactive Tools

Free tools for the shop floor — the kind of thing I build for real, playable in your browser. No sign-up, no upload: everything runs locally and nothing leaves the page.

Hear the Chatter

A stability lobe diagram you can drag around — and listen to. Real regenerative-chatter physics with audio, plus a variable-pitch toggle.

G-code Time Auditor

Paste a CNC program and see where the seconds go — cutting vs rapids, air cuts, tool changes, dwells — and what's recoverable.

Macro B Playground

A FANUC-style macro interpreter with a step debugger — run WHILE loops and IF GOTOs, watch #variables change, see the toolpath draw.

Vision Lab

Presence/absence part inspection in your browser — threshold, blobs, PASS/FAIL — plus a lighting-sabotage button that teaches the real lesson.

Surface Finish Calculator

Theoretical Ra & Rt for turning and ball-nose milling — with the scallop profile drawn live as you drag feed and radius.

Thread & Tap-Drill Calculator

Metric + UNC/UNF tap drills from % engagement, stock drill matches, and a live cross-section of the thread actually engaging.

Guard Band Visualizer

Watch measurement uncertainty eat your tolerance zone — TUR, guard bands, and the % chance a borderline part gets accepted.

OEE Calculator

Availability × Performance × Quality from one shift's numbers, with every formula shown. Free, no sign-up.

More on the way — a chatter simulator you can hear, a Macro B playground, and an in-browser vision lab. Want one of these sooner, or something custom for your shop? Get in touch.
