Laser ablation technology, with its high energy density, excellent focusing capability, and non-contact nature, has become an ideal choice for processing superhard materials. To develop a CNC laser machine tool for processing superhard cutting tool materials, a kinematic model of the machine tool was established using the D –H method, determining the range of motion for each axis and defining the workspace based on the machining coordinate system. Subsequently, post processors were developed using various methods such as MATLAB, Python and UG to convert the machining instructions into executable instructions for the machine tool control system. Finally, a virtual machine tool was created in VERICUT for motion simulation to validate the accuracy and effectiveness of the kinematic model. The simulation results confirmed that there were no collisions or programming errors during the machine tool motion, indicating the accuracy and reliability of the constructed kinematic model. The study also revealed that incorporating a dual rotary table increased the workspace of the machine tool by 1.9 times when the laser focal length was set at 130 mm, thus meeting the requirements for more complex machining tasks.
