This paper describes a concept of a novel webbased CAD software for gear shaper cutters, including its core implementation aspects. Web-based system is proposed as a better alternative to traditional desktop CAD systems based on case study of Dathan Tool & Gauge Co. Ltd. One of the main issues in the development of a web-based CAD system is the need to process and, subsequently, visualise a lot of technical product drawings and sketches. Conventional web-oriented design systems are either integrated with specialised CAD software for processing technical drawings or use dedicated graphics visualisation tools. The proposed web-based CAD software tool for gear shaper cutters relies on technologies supported by regular web browser programs with no need for additional client software and is based on the freely available components and standards.
