Cutting properties of drills and milling tools

Laser distance sensor OptoNCDT-ILD 1402 from Micro-Epsilon (max. measurable distance: 50 mm)
Various measuring amplifiers, including the HBM MX410B
Picomax 21-M tooling machine from Fehlmann (50 - 6300 rpm)

How is the test usually carried out?

The Chinese standard YY 91064 provides a rough guideline. However, the sample material to be cut, the applied load and the speed often vary greatly between customer projects.

How many measured variables can be recorded simultaneously in these tests?

The maximum number of sensors that can be used simultaneously is currently eight. However, the number can also be lower depending on the measurement frequency or other factors.

Are these test methods also offered validated?

In principle, such special solutions can also be validated. In most cases, however, the effort involved is high, so that no validation is carried out. Nevertheless, the sensors are calibrated either according to DaKKs or according to the manufacturer's factory standard.
