CNC controllers, working as a brain for manufacturing automation, are high valueadded
products accounting for over 30% of the price of machine tools. CNC technology
is generally considered as a measure of the level of manufacturing technology of
a nation, and is currently led by major advanced countries such as USA, Japan, and
Germany. CNC technology, which cannot be developed with one single technology
but needs to integrate computer technology, hardware technology, machining technology,
and so on, is often referred to as “The Flower of Industrial Technology”, and
requires a strategic long-term support, mostly on a governmental level.
Despite its significant role, textbooks on CNC controllers are quite rare worldwide,
with a few published in the 1970s and some later. However, the earlier ones
mostly dealwith conventional technologies,while the later ones deal with fragmental
contents, mostly focusing on part programming and machine operation. This book
is written by several authors in collaboration who have long experience in CNC development,
education, and research, and is designed as a highly focused textbook
to provide knowledge on the principles and development technologies of CNC controllers.
Therefore, this book can be used as a main textbook for courses related to
CNC in such departments as mechanical engineering, precision engineering and control
engineering, and as a guide for those working on CNC development in industry.
If highly descriptive portions are taken out, it can also be used as lecture material in
technical colleges.
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. |
