Incorporation of tool deflection in tool path computation: Simulation and analysis

An improved static model for tool deflection in machining of Ti–6Al–4V acetabular shell produced by selective laser melting

“…The errors are less than 2% between FEM3D and the experimental measurements can be explained by the fact that the FEM3D takes into consideration the exact tool geometry and second moment of inertia in agreement with literature [5][6][7][8]. Likewise, a gap between TWSM, THSM and experimental measurements when we put the value of second moment of inertia by effective and equivalent methods can be justified by the fact that these methods are appropriate for face milling cutters (cutters with flat head).…”

“…Figs. 8, 9, 11 and 13 show the accuracy of FEM3D model compares to experimental measurements and prove that this numerical method has high accuracy for complex shape deflection [5][6][7][8]. Fig.…”

Error compensation in flexible end milling of tubular geometries

“…But it was reported in previous research attempts (Suh et al, 1996;Depince and Hascoet, 2006) that the modified tool center position changes radial depth of cut and cutting forces. Therefore, the procedure of compensation must be performed iteratively considering change of cutting conditions due to modification of tool center position towards nominal position.…”

“…It shows positive error in form of 'under-cut' and its variation along axial direction of the cut is quite complex due to combined effect of tool and workpiece deflections. For application of compensation strategy (Suh et al, 1996). discussed in earlier subsection, any point on surface error profile can be selected as compensation reference.…”

Active integration of tool deflection effects in end milling. Part 2. Compensation of tool deflection

“…This method is an improvement of the methodology proposed in Ref. [12]. The method described by Suh has several drawbacks: the convergence is not always assumed, the method is linked to a factor that cannot systematically be determined and it takes into account the tangential deflection that is negligible and can induce convergence problem.…”
