Metal Sawing Tool Making TRIZ Cases

Optical diameter measurement with a predictive model tracks abrasive wire wear in real time at high running speeds without image processing.

A modified plunge tooth and enlarged gullet improve plunge-cut accuracy, chip removal, and cutting control in reciprocating saw blades.

Single-pass dry end milling removes the heat-affected zone while defining uniform saw tooth profiles with less heat, time, and tool wear.

Pre-setting coil stock before tooth grinding avoids tooth-tip deformation and keeps saw blade tooth geometry consistent for smoother cuts.

Linear gullet bottoms and angled back portions redirect chips downward, cutting scatter and noise in resin and aluminum sawing.

Selective hardening of the trailing edge improves clearing saw blade wear resistance while keeping the leading edge fileable for sharpening.

A tapered cutting bead combines defined and undefined edges to cut larger chips, reduce wear, and lower sawing energy and dust.
