This study provides an innovative web application developed for supporting job shops in performing design, automated process planning and numerical control (NC) code generation for mill-turn parts. With the ever-increasing importance of e-commerce/e-business in the manufacturing industry, the traditional standalone computer applications will be replaced by web-based applications deployed via Internet. This will further internationalize competition in manufacturing, and for Kansas small manufacturers to be globally competitive, appropriate web technologies must be developed. This application has a built-in user interface for the user to design mill-turn parts from a predefined feature library. The process-planning kernel on the server automatically executes all process planning tasks like machinable volume identification, operations sequencing, tool selection, parameter selection, etc. and gives NC code. The interface is also capable of showing the tool path animation for the part, for user verification. This application uses client-server architecture and is developed using Java technologies. This web-based application can be accessed via Internet using any standard web browser. This web application will allow Kansas manufacturers to cut costs, increase machine utilization, and minimize turnaround time, all of which are essential in the competitive global market.
