One-trip cutter plate for rotary cutting tool, has incorporated abrasion sensor provided by sensor line in form of conductive film applied along cutting edge of cutter plate

摘要

The one-trip cutter plate (71) has a planar base (72) provided with a cutting edge (79) between one surface (75) of the cutter plate and its side flank (78), with a sensor line (82) provided by a conductive film applied along the cutting edge. The sensor line is coupled to an external electrical circuit via contact regions (83,84) at the boundary edges (88,89) of the cutter plate.
