| Multi-axis precision servo control system theory is studied in this paper. The system, through software program to realize the functions, is consisted of PC and Maestro controller as hardware. The details of studies are listed as follows:(1) In this thesis, studied the synchronization control technology in multi-axis system. Then reviewed the development and present situation of the fields of multi-axis servo system and synchronization control technology.(2) The composition and working principle of are studied. Especial in function structure of Maestro motion controller and the main features of Elmo servo driver. The building process of the coordinate system in NC machine is described combining the actual structure of NC system.(3) Research on the solution of motion trajectory, including the acceleration and deceleration control of servo motor, the T-curve velocity planning, the S-curve velocity planning, the trigonometric function-curve velocity planning. The advantages and disadvantages of three curves are analyzed and compared. According to the result, the actual motion trajectory of servo motor is solved.(4) The analysis and introduction about the process in wire processing. On the basis of this analysis, NC system software is developed using the modular design method. The NC system software includes communication module, work origin study module, error handling module, data processing module etc.(5) Some wire machining experiments are carried out, including the communication between pc and controller, function of study, database access and error handling. The results form experiments indicate that the NC system is credible and veracious, also the trajectory planning measures studied above are impactful in reducing mechanism impact.
