iPhone
Point your iPhone at the cut. ChipSense listens for chatter and watches the grain in real time — and tells you to ease off before the tool bends or breaks.
ChipSense turns your iPhone into a real-time cutting coach for your CNC router or mill.
It does something no other app does: it fuses AUDIO and VISION. ChipSense listens to the cut through the microphone to detect the acoustic signature of regenerative chatter and rising tool load, and at the same time reads the wood grain through the camera to spot knots and hard, figured areas before your bit reaches them. It combines both into a single, live Cut Risk — and tells you exactly when to ease the feed, and when to stop.
WHY IT MATTERS
• Chatter and overload are how bits dull, snap, and ruin a workpiece. They almost always announce themselves in the sound of the cut — a few seconds before the damage.
• Hard grain and knots are visible before you hit them. ChipSense sees them coming.
• Catch either early and you save bits, save stock, and get a cleaner finish.
WHAT YOU GET
• Live cut-state read-out: Idle, Nominal, Heavy load, Chatter, Critical.
• Chatter detection tuned to reject spindle-synchronous tones (it knows the difference between the normal cut and self-excited chatter).
• Camera grain map that highlights knots and hard grain as a live heatmap.
• A fused Cut Risk that combines what it hears and what it sees.
• A clear feed advisory — ease off, hold, or all clear — with a suggested feed-rate override.
• Built-in demo scenarios so you can see exactly how it responds to a knot, chatter, or a clean cut, with no machine and no setup.
HOW TO USE IT
Prop your iPhone near the cutting zone with a view of the workpiece, start monitoring, and cut. ChipSense advises in real time. It is a monitoring and advisory tool — it does not control your machine directly.
