Computer Numerical Control (CNC) controllers are high value-added products counting for over 30% of the price of machine tools. The development of CNC technology depends on the integration of technologies from many different industries, and requires strategic long-term support. “Theory and Design of CNC Systems” covers the elements of control, the design of control systems, and modern open-architecture control systems. Topics covered include Numerical Control Kernel (NCK) design of CNC, Programmable Logic Control (PLC), and the Man-Machine Interface (MMI), as well as the major modules for the development of conversational programming methods. The concepts and primary elements of STEP-NC are also introduced. A collaboration of several authors with considerable experience in CNC development, education, and research, this highly focused textbook on the principles and development technologies of CNC controllers can also be used as a guide for those working on CNC development in industry.
The Technical Committee on Mechatronics formed by the International Federation for the Theory of Machines and Mechanisms, in Prague, Czech Republic, adopted the following definition for the term: Mechatronics is the synergistic combination of precision mechanical, electronic control and systems thinking in the design products and manufacturing process Due to developments in powerful computers, including microprocessors and Application Specific Integrated Circuits (ASICS), computational techniques, diverse technologies, advances in the design process of products and other factors, the field of mechatronics has evolved as a highly powerful and most cost effective means for product realization.
The purpose of this book is to evaluate strategies for future system design in multiprocessor system-on-chip (MPSoC) architectures. Both hardware design and integration of new development tools will be discussed. Novel trends in MPSoC design, combined with reconfigurable architectures are a main topic of concern. The main emphasis is on architectures, design-flow, tool-development, applications and system design.
"Most of the current college design and manufacturing curricula are primarily focused on computer aided design (CAD), while less emphasis is given to computer aided manufacturing (CAM). A great opportunity has been missed as the benefits of CAD/CAM cannot then be fully learned. Postprocessor plays a vital role in integration of CAD//CAM with computer numerically controlled (CNC) machines. Hence, postprocessor must be developed accurately. This thesis is composed of one paper. Paper I proposes a novel methodology to determine compensation vectors for the post processor of multi-axis milling center. The new approach that has been implemented in Paper I involves derivation of the analytical equations of NC code with compensation vectors for five-axis spindle-tilting type CNC milling machine and experimental procedure to acquire the compensation vectors. This ensures that part would be machined as per the CAD drawing and accuracy within the limits of CNC machine. Furthermore, implementation of this procedure for the development of a post processor would streamline the process of integrating CAM systems for multi-axis CNC milling centers. The integrated system is being used to support research and education projects to accurately and quickly produce parts"--Page iv.
This book gives a comprehensive introduction to the design challenges of MPSoC platforms, focusing on early design space exploration. It defines an iterative methodology to increase the abstraction level so that evaluation of design decisions can be performed earlier in the design process. These techniques enable exploration on the system level before undertaking time- and cost-intensive development.
A multiprocessor development system has been designed and a prototype system is being constructed. The system, known as Concert, is intended to support multiprocessor research efforts at M.I.T. The motivation for Concert and the project history are summarized briefly. Some intended applications are also identified. The system incorporates the RingBus architecture, a novel scheme for interconnecting processors and memory in a tightly-coupled multiprocessor system. The architecture is described both in its general form and in the particular implementation used in the system. The results of some analysis and synthesis of the architecture are summarized. The design of the Concert multiprocessor development system is described, with particular emphasis on the tradeoffs considered in the design process. The design of two particular hardware modules is discussed in considerable detail. Finally, some suggestions are offered for future use of the system and further investigation into the RingBus architecture. (Author).
The continous development of computer technology supported by the VLSI revolution stimulated the research in the field ·of multiprocessors systems. The main motivation for the migration of design efforts from conventional architectures towards multiprocessor ones is the possibi I ity to obtain a significant processing power together with the improvement of price/performance, reliability and flexibility figures. Currently, such systems are moving from research laboratories to real field appl ications. Future technological advances and new generations of components are I ikely to further enhance this trend. This book is intended to provide basic concepts and design methodologies for engineers and researchers involved in the development of mul tiprocessor systems and/or of appl ications based on multiprocessor architectures. In addition the book can be a source of material for computer architecture courses at graduate level. A preliminary knowledge of computer architecture and logical design has been assumed in wri ting this book. Not all the problems related with the development of multiprocessor systems are addressed in th i s book. The covered range spans from the electrical and logical design problems, to architectural issues, to design methodologis for system software. Subj ects such as software development in a multiprocessor environment or loosely coupled multiprocessor systems are out of the scope of the book. Since the basic elements, processors and memories, are now available as standard integrated circuits, the key design problem is how to put them together in an efficient and reliable way.
Current multimedia and telecom applications require complex, heterogeneous multiprocessor system on chip (MPSoC) architectures with specific communication infrastructure in order to achieve the required performance. Heterogeneous MPSoC includes different types of processing units (DSP, microcontroller, ASIP) and different communication schemes (fast links, non standard memory organization and access). Programming an MPSoC requires the generation of efficient software running on MPSoC from a high level environment, by using the characteristics of the architecture. This task is known to be tedious and error prone, because it requires a combination of high level programming environments with low level software design. This book gives an overview of concepts related to embedded software design for MPSoC. It details a full software design approach, allowing systematic, high-level mapping of software applications on heterogeneous MPSoC. This approach is based on gradual refinement of hardware/software interfaces and simulation models allowing to validate the software at different abstraction levels. This book combines Simulink for high level programming and SystemC for the low level software development. This approach is illustrated with multiple examples of application software and MPSoC architectures that can be used for deep understanding of software design for MPSoC.
Computer Numerical Control (CNC) machines are used in a variety of ways in supporting the development of new products and processes and can provide an excellent means to expose students to standardized control procedures as well as offer opportunities to effectively supplement the teaching of control systems and instrumentation. Using Mach3 for software control and stepper motors for power transmission, a relative low cost but effective CNC Laser machine was developed by Western Carolina University (WCU) and Asheville-Buncombe Technical Community College through a joint partnership. This paper will present a logical approach to developing such a system and describe how applications have been integrated into curricula at both the two-year and university level programs through Project Based Learning (PBL). Educational merit and approaches will be described relative to respective educational levels.
