Abstract

[Given the general optimization context given in the preceding chapters, we will now analyze a particular but important problem of sequencing the machine rotations. There exists a variety of research focused on the orientation of the cutting tool. The survey of which is given in Chap. 1. However, the accuracy is also affected by the way the orientations are being achieved. In other words, the kinematics error depends not only on the characteristics of the surface versus the tool orientation but on the previous rotations as well. The “history” of rotations becomes in particular important in the vicinity of the stationary points of the desired surface where the tool could make abrupt changes in the orientation. However, such analysis is not provided by commercial CAD/CAM systems such as Unigraphics, EdgeCam, Vericut, etc. Besides, only a few recent research papers deal with the subject.]
