Abstract
This thesis deals with not only the tool path planning and cutting deviation analysis for sculptured surface machining but also kinematic transformation algorithms for different types of 5-axis machine centers. A generalized expression is presented first to define the cutting contact location for any type of milling tools. The actual cutting contact point and the cutter location can be determined by tool orientation angles. Furthermore, the gouge avoidance criterion is utilized with the admissible tool orientation classification and a localization algorithm is derived to calculate error estimation along tool paths. The inverse kinematics between two independent chains about the tool and workpiece is solved and the tool compensation procedure is established for each 5-axis machine configuration. Computer implementation and illustrative examples are also executed for qualitative and quantitative analysis. The theoretical and practical issues associated with this thesis could help to generate 5-axis CNC tool paths automatically from CAD model and to promote general post-processor developement for futher applications.
