This study proposes a method for developing a C# based application dedicated to the geometric generation of screw rotor (SR) profiles. The application supports the construction of rotor profiles utilizing a range of parametric and non-parametric curve types, enabling high flexibility in curve selection to suit specific design requirements. The rotor profile (RP) generation process is executed efficiently through user-defined input parameters, ensuring streamlined computational performance. The generated profiles exhibit continuous and smooth curve transitions, avoid geometric undercuts, and preserve the intended dimensional integrity. Additionally, the application incorporates algorithms to ensure conjugate rotor pairs are synthesized under accurate meshing conditions, maintaining kinematic compatibility. The validity and versatility of the proposed approach are substantiated through multiple numerical case studies.
