Study On Automatic Generating NC Code Based Machining Features And UG

In the recent years, the automatic generation of NC code has been paid more and more attentions. According to the demand of enterprises, an approach to automatic generation of NC code based on machining features and UG is proposed in this thesis. In order to validate the proposed approach, a prototype system is developed and some test results are given.The thesis is organized as follows:Chapter 1 introduces the related work first, then points out the main problems of the current NC code generation methods, and finally ends with the objectives and primary research contents of this thesis.Chapter 2 introduces the requirement analysis of machining features and UG based automatic generation of NC code first, and then presents the framework of proposed approach.Chapter 3 presents an approach to mapping between the machining features recognized and the machining methods provided by UGChapter 4 presents a new method of selecting optimal tools for machining multiple pockets and gives some test results.Chapter 5 describes the implementation of the prototype system of machining features and UG based automatic generation of NC code.The final chapter summarizes the main results and makes conclusions of the thesis. Some future research work is also described.
