Welcome to my site! This website is my working infomation about cnc  (Computer Numerical Control). There are many subjects on cnc,  motion control is the basic of this kind of this machine. The  motion control is consists of path generation and position control.  In order to build some motion control  system,you need a real-time system including another non-realtime work  together , graphic user interface, file handling, Input/ Output  control. A system that meet these requirement may be a group of many processor  module running it job, and work together, or you can build
this system using single cpu and real-time operating system                    

The author want to share knowledge on cnc technology. In the beginning of  learning, it very hard to find any reference for cnc development. The real-time os play an important role in electronic and computing industrial. You can reserse real-time behavious for time-critical and display the system status in the same time using only single cpu ;)  Today, professional embedded system is mainly implemented using rtos (or embedded operating system)

 In this document I have provided and guided about motion control  and related.  I did my best, but I know there may be errors. this  document do not intend to be the last word on this issue.

 Any machinery capable of harming persons must have provisions  for completely removing power from all motors,  etc,  before persons enter any danger area. All machinery must be designed to comply with local and national safety codes, and the authors of this tuturial can not, and do not, take any responsibility for such compliance.
