Simplified deformation models of the plain milling cutter subjected to cutting forces loads when milling the aluminum alloy Al 7075

The problem of geometric modeling of the plain milling cutter and its deflection under the influence of loads mapping forces occurring during the milling of the Al 7075 alloy surface is discussed. In modeling, 2 types of plain milling cutters are included: with rectilinear cutting edges and with helical cutting edges. The influence of concentrated forces and different distributions of loads mapping the cutting forces, is considered. Conclusions are drawn regarding the influence of the force inclination angles relative to the selected axis of the coordinate system on the generated effective stresses and cutter deformations. The finite element method was used to calculate the displacements, deformations and stresses.
