2) the most intensive initial wear is in the cutting length L up to 3270 m--the width of the cutting edge b is rapidly increasing.
The intensity of the cutting edge wear gets even lower in the cutting length L up to 26100 m where monotonic wear takes place.
Some local fractures on the cutting edge occurred due to fatigue and built-up edge formation .
Chipping and breakage of the cutting edge are the most common causes of cutting tool failure.
Joachim Koller, responsible for technical service at Seco says: "Because of the round insert, the cutting edge has a larger radius, which in turn allows higher feedrates.
Tool cost was also greatly reduced thanks to the longer cutting edge and the fact that on the round inserts we can use up to 20 edges, not just the 14 that Seco promised.
The Idahone ceramic stone is as effective as the Arkansas stone in achieving cutting edges
with few irregularities on Hu-Friedy 11/12 Gracey curets and in achieving equally smooth corresponding root surfaces on extracted human teeth.
When cutting edges overlap each other, the resultant cutting forces are lower, the tools are always under load, stability is improved, vibration is reduced and the required machine power during the milling operation is lowered.
Clamping the inserts on heavy-duty cutters with multiple inserts provides full-effective helical cutting edges and the possibility to machine at large depths.
Products like HELIMILL, HELIBALL, HELIFACE, and DO-GRIP all use curved cutting edges
to gently shear and separate the chip.
Insert cutting edges
may be positioned relative to both radial and axial planes in either positive, neutral, or negative rakes.
