Circular Saw Cut

How it's made

Source

a circular saw accelerates from rest to 4500-5700 rpm; motor commutation has 6 and 12 orders. Blade teeth add a 24- or 40-tooth passing band, while broadband air follows rotational speed.

Body

wood and the tool housing colour friction at 280 and 730 Hz with broad, damped resonances. Cutting is irregular 180 Hz-7 kHz noise, with small filtered chip impulses rather than metal ringing.

Envelope

0.6 s spin-up, board entry at 0.72 s, 1.1-1.8 s cut, then unloaded recovery and 0.8 s coast. Rounded entry and exit ramps prevent clicks; blade pitch and air brightness fall together on shutdown.

Modulation

cutting load lowers speed by 5-14%; grain wander and 75-95 Hz blade rotation roughen rasp. Tooth-rate amplitude modulation adds fine serration without unbounded harmonics or distortion.

Variation

seeded grain, chip timing and 0.6% motor tuning vary instances. Presets change blade tooth count, speed, board resistance and cut duration: quick softwood, fine plywood, hardwood and rip cut.

Space

dry, close mono source; no room reflection is baked into the effect.
