“…The material removal rate used for this is based on the required surface quality. Since the highest metal removal rate and the highest surface quality are mutually exclusive, the cutting values that meet the requirements of both process parameters (performance and quality) are used [7,8].…”

“…Consequently, the operating speed of the tool can exceed the lowest eigenfrequencies, particularly in high‐speed‐cutting (HSC) applications, leading to the occurrence of resonance during run‐up or run‐out. Figure 1 shows an example of a long slender tool for milling of a plaster mold [1]. The lowest bending eigenfrequency is given by

f_{01}=205\,\text{Hz}

and an operating speed up to

250\,\text{Hz}

is used.…”

“…Due to geometrical errors or inhomogeneous mass properties, plastic deformations or even a fracture separation can occur in the critical speed range. To prevent such occurrences, different investigations have been done, which mostly use passive methods to reduce oscillation [1, 3–5, 11, 12]. The main idea of this paper is the usage of a hollow shaft, which is partially filled with a balancing mass.…”

High‐speed‐cutting) milling is an extensively used production process in tool‐making and mold‐making industries. For the purpose of a self‐balancing tool, a hollow shaft is used and filled partially with a fluid. This talk presents different beam and shell models for the investigation of nonlinear vibrations. Therefore, different theories are compared with respect to the influence of geometrical nonlinearities, spin‐softening as well as stress‐stiffening, and also shear deformation. Additionally, a stochastic Wedig–Dimentberg approach is presented for the simulation of a spatial distributed unbalance. Starting with the nonlinear kinematics for the tool‐deformation Hamilton's principle is evaluated for the variational formulation of each model. Regarding to the shear deformation, the theories of Euler‐‐Bernoulli and Ehrenfest–Timoshenko (beam models) as well as Kirchhoff‐‐Love and Mindlin–Reissner (shell models) are used. In the following up, the variational formulation is discretized under usage of a global Ritz approach on the one hand, and on the other hand with a local finite element (FE) discretization. Afterward, the governing system of differential equations is solved and discussed. Different results of rotating and nonrotating tools are presented, which show the available options of each theory and also their limits. In particular, results of the eigenfrequencies including their stochastic distribution, stationary deformation, stability behavior, and various time solutions are shown.

In this article, technological parameters such as cutting speed, feed rate and depth of cut and their relationships with average power are investigated and modelled using statistical design of experiments. This allows a quantitative and qualitative description of the relationship between average power and process parameters. The analytical knowledge gained from the tests provides the conditions for optimising the energy consumption of the turning process.
