Experimental Investigation of Cutting Conditions from the View of Force Load at High Speed Milling

Abstract

The article deals with the experimental investigation of cutting conditions from the view of force load during machining high alloyed tool steel EŠ 419556 (standard by Škoda a.s. Pilsen, based on DIN 1.2326) at high speed milling. The aim of presented research is investigation of the most favourable contact and cutting conditions to minimize the power load of the cutting edge. Processing of measurement results within presented investigation was focused only on the components of cutting force FC (tangent) and FCN (normal) that adequately characterize the cutting process. The experiments were also carried out at cutting depth (ap) changing during high speed milling. The obtained results are presented in the paper by means of graphs that clearly show the behaviour of cutting force components at given conditions.
