The air flow around a milling cutter investigated experimentally by particle image velocimetry

Popis výsledku v původním jazyce

The movement of air around a rotating milling cutter is investigated experimentally by using the optical non-intrusive method PIV (Particle Image Velocimetry). The milling cutter is located next to a flat surface simulating the processed material. The Flow is studied in three planes in axial × radial direction with phases 90°, 180° and 270° from the point closest to the flat desk. The PIV timing has been synchronized with the cutter rotation. We observed plumes governed by centrifugal force (as in Taylor-Couette flow) acting on the air teared with the rotating milling cutter. In average, the air flows along the milling cutter from its front end forming a large-scale vortex mostly apparent at higher velocity and at the plane opposite to the processed surface. At the 90°plane, the air is sucked towards the milling cutter, while at the 270°plane, the air is pushed away from it. Spatial correlation function shows a weak periodicity close to the cutter and widening of its shape with increasing distance from the milling cutter.
