“…Recent research associated with the micromilling process has focused on issues such as machine tool design [8][9][10][11][12][13], miniature cutting tools [14][15][16], process mechanics [17,18], surface finish [19] and CAM systems [20][21][22]. However, in the research literature there is relatively little attention to the micromilling process planning issue, i.e.…”

“…With reference to machine tools, various methods for the reduction of vibration excitation resulting from highly dynamic feed motions have been developed and investigated. A comparison of the jerk decoupling [2] (also known as pulse decoupling, see Figure 1a), force compensation [3] (see Figure 1b), floating principle [4] (see Figure 1c), and Kinematically Coupled Force Compensation [5] (KCFC, see Figure 1d) can be found in [6]. These principles facilitate the reduction of drive reaction forces, which may cause an excitation of the machine frame.…”

“…Both methods use a redundant axis configuration, whereby the relative motion required for the machining process is generated between the two slides moving in opposite directions. In KCFC, the motion is distributed within the control system according to the mass ratio Km in Equation (1), which has to be known as precisely as possible, since it determines the quality of force compensation according to Equation (2). Km = mB/mA (1) mA × aA = mB × aB (2) For the Floating Principle, the division of motion inevitably results from the mass ratio.…”

The Floating Principle is superior to the KCFC in terms of energy consumption due to the use of only one drive [6].…”

Typically, the feed dynamics of machine tools are limited to reduce excitations of machine structure oscillations. Consequently, the potential increase in productivity provided by electrical direct drives cannot be exploited. The novel approach of the Kinematically Coupled Force Compensation (KCFC) combines the principles of redundant axes and force compensation to achieve an increase in the machine’s feed dynamics. Because the drive reaction forces are directly applied to the machine frame, they cancel out each other perfectly if the relative motion at the Tool Centre Point (TCP) is split according to the mass ratio of the slides. In this paper, the principle of KCFC is introduced briefly and possible improvements in the design of machine structures and control are presented. The results of experimental investigations obtained by means of a 1D-KCFC Test Bed illustrate the effectiveness of the principle. Moreover, a further increase of the compensation quality can be achieved by decoupling the force flow from the machine frame, by means of elastic elements. Finally, an outlook on future research with reference to the 1D-implementation as well as possible applications of the KCFC in highly productive processes is given.

Sus características mecánicas permiten caracterizar las estrategias de mecanizado óptimas para cada operación (Brecher, Wenzel, and Klar 2008) y mejorar las condiciones de corte en la máquina herramienta analizando su influencia en el desgaste de la herramienta y calidad superficial del proceso (Krebs and Kersting 2014).…”
