The article is a comprehensive project, which involves several fields such as Mechanics, Electronics, and computer.The article states the principle of the rotary table, it state the mechanical structural design and the temperature control system in detail. Because the rotary table must achieve the high tracing precision, the rotary table structure is the complex axis system. The outer axis system finish the larger rang horizontal and vertical movement, it is used to achieve the wide tracing task. The inner axis system is used to achieve the accurate tracing task. The outer axis system follow with the inner axis system . in order to achieve the watch axis, we design the gyro servo system .Though the theoretical analysis and experimental verification, the design of this measurement apparatus is reasonable, and the precision is also adequate.
