The use of CAD/CAM technology is mandated and expanding in the orthotic and prosthetic business as a result of the demand for faster, easier, and better fabrication of molds for orthoses. In comparison to the traditional, hand-made orthoses, this method of manufacture marks a significant advancement. This strategy has a number of drawbacks, though, which prevent its wider implementation from happening in real life. The purpose of the doctoral thesis is to develop and apply new methodologies as well as a new technical solution for orthoses using CAD/CAM technology that will significantly improve current processing technology by defining a unique numerical machine with a parallel kinematic structure and accompanying software for inverse and direct kinematics and more technical features. Results are analyzed, and the systems functionality is assessed, using the developed simulation program module and data collected from measurements made while the machine was in operation. These measurements are related to speed, repeatability, accuracy of the obtained surface, and program implementation stability. It was determined that the new technical solution methodologically and performance-wise permits technological advancement in the production of orthotics with the development of orthotic hardware and software for the same
