In addition, the CAD system includes some more utility modules, such as module of gear calculation of error of gear profile, module of gear measurement, module of looking up nation standard of gear.

另外，在齿轮CAD系统中还设计了齿廓误差计算、齿轮测绘及齿轮国家标准查询等一些具有较大实用价值的模块。

The measurement system and measurement method of gear parameters based on CCD were introduced, and then influence factors of measurement precision were analysed.

介绍了基于CCD齿轮参数测量系统的组成及其测量方法，并对影响测量精度的因素进行了分析。

The new method without movement paralleled with the axis of the gear makes the lead error measurement can share same generating system with profile measurement.

此方法不需要测头沿齿轮轴线方向的运动系统，利用齿形测量系统即可测量齿向误差。
