| Along with the flying development of micro-electronics technology and microcomputer technology, NC carver will be widely used .But compared with overseas carvers ,the technique of homemade ones is in a very low level.In this paper, the control software of the high speed and high precision NC-carver is developed. Make an overview on current situation of NC technology and carver technology, and then put forward the aim of the control software of NC caver. Discuss the characteristics and the application of NC caver , and its structure and main functions. Methods of data transmission between CAM and CNC, choose USB as the transmission interface. The embedded system theory is discussed. Put forward the software structure based on ARM processor. Study the interpolation technology, kernel part of the software. And also study several key technologies of the control system: pretreatment and control of machining speed, make an auto-control technique of acceleration and deceleration into use , which is with "look forward" function ,so that ensure the precision and the stabilization of machining. And at last, prospect the trend of the caver control software based on embedded system.
