The design method of the system and the characteristics of its components are studied in detail. By using this system, a known free-form surface can be measured and its profile error can be assessed.
详细研究了测量系统各组成部分的特性和系统的实现方法，完成了已知自由曲面的测量和轮廓度误差评定，实现了未知自由曲面的测量和数学模型的建立。
It is designed with heavy workload and machined with high difficulty as its profile is a kind of free-form surface in space.
由于叶片的型面是一种空间自由曲面，因此设计工作量大、加工难度高。
