The objective of CNC machining is to produce mechanical parts with designed quality most efficiently. To generate CNC tool paths for machining a sculptured part using a three-axis CNC machine, surface geometry, cutter shape and size, as well as tool path interval and direction need to be...
The essence of competition among modern enterprises is time; hence the time for product development must be greatly reduced. This paper presents a new process model of product development with uncertainty based on activity overlapping, borrowing ideas from the uncertainty model and activity...
This paper is mainly concerned with studying the e-manufacturing scheduling issue based on the bills of materials (BOM) flows of products. On the basis of e-manufacturing philosophy, a genetic algorithm (GA)-based scheduling model for physical e-manufacturing cells is put forward. By means of...
In order to represent, analyze, optimize, and manufacture a component made of multi-heterogeneous materials for high-tech applications, a computer model of the heterogeneous component needs to be built first. Heterogeneous materials include composite, functionally graded materials, and...
One of the bottle-necks of computer numerical control (CNC) machining is the CNC programming. It relies on the experience and skills of the CNC programmer for the generation of the CNC program. The intelligent process-planning system described in this paper generates a process plan automatically...
A flexible manufacturing system (FMS) is a complex manufacturing system and it demands a robust control software for its scheduling, planning and control functions. This paper describes the development of an agent-based infrastructure for the control of a cellular FMS. The FMS in this project is...
An approach to extract machining features for casting parts is presented. It is capable of recognizing interacting machining features. There are five phases in the recognition process: Boolean difference of the final part model and the raw part; identification of machining faces (M-faces) from...
