Reconfigurable modeling technology of similar-structure products configuration design

The product configuration modeling is a key technology to realize configuration design.Most of the researches were mainly conducted focusing on how to establish a product configuration model,but were short of the consideration about the application scope and dynamic change features.In this paper,the reconfigurable modeling technology of similar-structure products configuration design is studied to enhance the generality and diversity of product configuration models,and to facilitate the dynamic upgrade of configuration models.The configuration components of products with similar structures are divided into sharable configuration components,essential configuration components and optional configuration components,so the construction of reconfigurable model of configuration design can be converted into the set operation of configuration components.The horizontal adjusting reconstruction of configuration model is carried out through the adding,replacing and deleting of configuration components,the vertical adjusting reconstruction of configuration model is carried out through the parametric deformation of configuration components,and the variable topological configuration model reconstruction can be realized through the transformation of partial structure of configuration components.Finally,NC machine products are used as an example to analyze and verify the reconfigurable modeling technology of products with similar structures.The speed of NC machine configuration design is found to be improved,and the number of NC machine configuration design models is decreased.And the reconfigurable design system of NC machine products is developed.The proposed modeling technology provides references for the processes,methods and steps of model reconstruction.

FPGA based failure monitoring system for machining processes

To be adapted in an easy and economical manner to several machining processes is a desired characteristic in any proposed tool condition monitoring system so as to detect or avoid failures in machine tools. Many modern rotating machines have a servodriver which may, without sensors, acquire a current signal which is directly related to the cutting forces and then be correlated to the cutting tool conditions. Most of the reported systems are designed to work only in one machining process; yet the novelty of this paper is the fact of presenting a hardware signal processing unit implemented in a single field-programmable gate array (FPGA) for acquisition, conditioning, and basic signal monitoring in several machining processes. The system has been proven in industrial processes as well as in laboratories with satisfactory results in both cases. This model is reconfigurable and scalable so that it may be adapted to diverse conditions as an economical stand-alone unit since it does not require either computers nor microprocessors.

We present a reconfigurable system to detect and indicate online and in real time, the cutting tool conditions in high-speed face milling. It consists of a data acquisition system (DAS) and a hardware signal processing (HSP) unit.

The system operation is divided into learning and monitoring modes. The tool condition is indicated by an alarm signal, one LED indicator, and a message shown on four-digit seven-segment displays. In all experiments, the system correctly detected the tool condition. The proposed system is fast, compact, reliable, and economical, and no modification of the machine-tool structure is required.

Reconfigurable filtering system for sensorless signal acquisition in machining processes

Tool condition monitoring is a major problem that must be handled in order to detect and prevent failures in machine tools. Most modern rotating machines have a servo driver whence it is possible to acquire without sensors a current signal which is associated with cutting forces and cutting tool condition. This paper presents a hardware signal processing unit implemented in a field programmable gate array to acquire and condition signals from several machining processes. The system has been tested in both industrial and laboratory processes, producing satisfactory results. The design is reconfigurable in situ, since a few internal registers are programmed dynamically without recompilation which allows the same unit to be applied in different processes; the content of this memory is a set of filter coefficients. This implementation guarantees an inexpensive stand-alone unit since it does not require computers or microprocessors to process signals from different machinery as preparation for further processing.
