Résumé	CNC tool path generation is the computational process of determining the precise sequence and trajectory of tool movements required to machine a workpiece on computer numerical control (CNC) machines. Developed from the intersection of numerical control automation and computational geometry in the 1990s, this method translates CAD designs into executable machine instructions, enabling efficient and accurate manufacturing of complex parts.	The Denavit-Hartenberg (DH) convention is a systematic mathematical method for assigning coordinate frames to the links of an articulated robot or mechanism, enabling compact representation and computation of forward and inverse kinematics. Introduced by Denavit and Hartenberg in 1955, this method uses only four parameters per joint to describe the spatial relationship between adjacent links, dramatically simplifying kinematic analysis and control of complex multi-jointed systems.
