ABSTRACT
Roundness error is refers to the profile on cross section perpendicular to the rotating axis of ideal circular movements. Roundness error can be measured with a variety of methods, such as V block method, aerodynamic method, light interference method, etc. With high precision spindle rotary precision roundness instrument, measurement convenience, fast measurement speed, and therefore the most widely used. Roundness instrument according to the structure of different spindle rotary and rotary table can be pided into two kinds. This paper discusses the roundness instrument is using rotary table measuring instrument. Mainly discusses the general design of the rotary table roundness instrument, roundness instrument, the working principle, design of mechanical structure and requirements of certain elaboration and roundness instrument precision column material choice, structure design, selection of motor and sensor selection for further analysis. This paper also introduces the software programming based on LabviewKeyword: Circular Degree; Roundness Instrument; The Mechanical Structure; Precise Vertical Prism; The Sensor；Labview

1.1 研究的目的和意义
在机械零部件的加工制造过程中，需要对具有配合要求或高精度形貌要求的回转类零件的圆度进行检测，例如电机轴。只有检测符合要求的产品才能被拿来使用。因此本课题的目的和意义是设计一个能够检测圆度的系统，保证该道工序的质量，避免不合格的零件进入下道工序加工，降低废品率，降低工件成本，为以后的机械行业的发展做出一点贡献。
