Management and Monitoring of RFIDbased Cutting Tool Information for Integrated Manufacturing

Abstract

Abstract-The demand of integrating manufacturing design and process planning with actual production activities such as cutting tool information is essential to enhance planning efficiency as well as improve simulation accuracy. However, cutting tools information that involves static and dynamic data is difficult to track causing the planning and simulation activities to be isolated, using outdated information and lack of reliability. This paper presents the initial functions of an Integrated Cutting Tool Management and Monitoring system (ICTMMs) utilizing RFID technology. RFID is used as a device to identify individual cutting tool as well as to track cutters data at production floor. Integration is possible with the use of STEP-NC as the exchange data format. User interface is designed using Labwindows. General overview are discussed based on STEP-NC input file. The development of ICTMMs helps to simplify management of cutting tool at production floor and support the integration of tool information throughout the manufacturing chain.Keyword-Tool management, RFID, STEP-NC I. INTRODUCTION Integrated manufacturing environment involves continuous interaction of various computer-aided (CAx) systems functions to ensure full information can be utilized in assisting various manufacturing activities. For example, during production planning activities, cutting tools data is essential for effective machining operation which is normally obtained beforehand based on operator's experience, catalogues or any theoretical documents. Following that, a complete product data is supplied to Virtual Machining System (VMS) to be verified through computer simulation, before the actual machining commences. Accurate machining simulation requires not only planned cutting tools details, but demands tools' information portraying true production floor data. The reliability of the simulation results therefore, depends on the information supply from CAx system with verification from production floor.Unfortunately, information supply regarding cutting tools from production floor is still insufficient since cutters are hardly being tracked and traced. This is also due to the weakness of traditional information management method in managing static and dynamic data of the cutting tools. Static data refers to the specification details of the cutting tools located at the production floor. Currently, cutting tools are available in various types and multiple functions. High amount of individual cutting tools in production floor results in an increase of difficulty in handling these cutters' information. Thus, performing inventory control is a big challenge in order to ensure accurate selection of tools in terms of its type, geometry, and expected tool life. On the other hand, dynamic data refers to the information of cutting tool that changes over its usage within certain period of time. One example of dynamic data is tool life where it decreases after being used when performing any machining operation. Since tool life is important to determine the e...

A Case Study- Monitoring and Inspection Based on IoT for STEP-NC Data Model

“…In short, most of the machine process monitoring research presented earlier based on WSN was developed under the G-code environment. Instead, little research was carried out under the Standard for Product Model Data Exchange (STEP-NC) environment which includes Hassan and Kadir [18], Zhong et al [19]. Hassan and Kadir [18] and Zhong et al [19] proposed innovations utilizing RFID technology and wired based sensors.…”
