About

Polygon Generator

Features
Read full description

Polygon Generator is a professional engineering tool for generating polygon turning profiles based on the kinematics of the Gellért polygon turning process. The application calculates and visualizes hypocycloid and epicycloid profiles derived from the actual motion relationship between the spindle and the eccentric carrier shaft. The generated geometry represents the real profile produced by the polygon turning mechanism rather than a purely theoretical mathematical curve. Features: • Generation of hypocycloid and epicycloid polygon profiles • Adjustable profile parameters (h, e and N) • Real-time profile visualization • Metric (mm) and imperial (inch) unit support • Export to DXF, SVG, PDF, PNG and TXT formats • User Guide with background information and operating instructions Polygon Generator is intended for engineers, machinists, toolmakers and CNC programmers working with polygon turning applications. The generated profiles can be used for design studies, manufacturing preparation, CAD integration and CNC programming workflows. The application may also be useful for industrial designers, graphic artists and creative makers seeking unique geometric forms for decorative, artistic or product design applications.
