“…The measurement was done in the middle of the X, Y and Z travels of the machine, X = 4,000 mm, Y = 600 mm and Z = 1,000 mm respectively, figure 9 shows the measurement results for the three machine axes. The [28] , tool deflection like Salgado et al [29] and machine stiffness like Rivin [30] studied. Salgado et al [29] concluded that these factors may be considered if the head stiffness is greater than 62 N/mm in the Y-axis, 33 N/mm in the X-axis and 67 N/mm in the Z-axis.…”

“…The [28] , tool deflection like Salgado et al [29] and machine stiffness like Rivin [30] studied. Salgado et al [29] concluded that these factors may be considered if the head stiffness is greater than 62 N/mm in the Y-axis, 33 N/mm in the X-axis and 67 N/mm in the Z-axis. The stiffness of the new head clearly exceeds these values in the three axes given that the total stiffness of the milling machine as a whole is around these values for the Y-and X-axes, and that the stiffness in the Z-axis is determined mainly by the stiffness of the ram, which is the most flexible element on this axis of the machine.…”

“…In machining by material removal, some variability due to geometric, kinematic, thermal, and mechanical errors (deflection of the cutting tool) are a source of generating geometric irregularities [1][2][3] affecting randomly the quality of the finite piece. Taking into account these uncertainties in the control procedures and optimization of cutting conditions is therefore of great interest for a better mastery of productivity and of the desired quality of the pieces.…”

Abstract. In this contribution, a bi-objective robust optimization of cutting parameters, with the taking into account uncertainties inherent in the tool wear and the tool deflection for a turning operation is presented. In a first step, we proceed to the construction of substitution models that connect the cutting parameters to the variables of interest based on design of experiments. Our two objectives are the best machined surface quality and the maximum productivity under consideration of limitations related to the vibrations and the range of the three cutting parameters. Then, using the developed genetic algorithm that based on a robust evaluation mechanism of chromosomes by Monte-Carlo simulations, the influence and interest of the uncertainties integration in the machining optimization is demonstrated. After comparing the classical and robust Pareto fronts, A surface quality less efficient but robust can be obtained with the consideration of uncontrollable factors or uncertainties unlike that provides the deterministic and classical optimization for the same values of productivity.

“…For touching workpiece in high-speed machining of dies and molds characterized by large-scale and deep cavity, LSFH is more suitable than those traditional hold systems such as the collet chuck and the static pressure expansive chuck because of its simple structure, high balance accuracy, and high clamping strength (Zhou et al 2012;Tony and Schmitz 2007;Zhang 2006). Several works had been carried out to investigate the stiffness and defection of the cutting tool system which will affect the machining precision and surface quality (Salgado et al 2005). Some scholars focus on the estimation of the geometrical accuracy in multi-axis milling process (Lamikiz et al 2008) and the topography prediction of ball-end milled surfaces, considering the tool parallel axis offset (Arizmendi et al 2008).…”

Background: In high speed milling of the dies and molds characterized by large-scale and deep cavities with the lengthened shrink-fit holder (LSFH), the machining error caused by the tool deflection is not allowed to be ignored. Methods: The deformation of the LSFH and cutting tool are predicted, and at the same time the machining error caused by this deformation are predicted too based on the milling force prediction model and the finite element model. Taking into account the complex mutual coupling between milling force and the deformation, an error compensation method is proposed based on a balancing iterative algorithm. Results: The compensation tool path is obtained and the off-line machining error compensation is achieved. Milling example shows that the machining error after compensation less 77.4 % than that of no compensation.Conclusions: The results demonstrate that the proposed error compensation method is reasonable and can greatly reduce the machining error.
