Effect of Sine Bar Manufacturing Accuracy on Angle Measurement
Sine bar is a practical accurate measuring implement which can measure indirectly or a machining tool for the accurate angle by sine principle. The effect of sine bar manufacturing accuracy on angle measurement is expounded by the angle measurement and calculation of the sine bar in this paper. Then the conclusion can be drawn that the angle can be get by measuring the length accurately through sine bar, and measuring a small-angle by sine bar which can reach the higher accuracy.
