When measuring the non radial nature of the front tool surface during precision part machining, the measurement error is caused by the size accuracy error of the center and center gauges themselves.
When comparing the drawn double line or single line tooth profile curve with the actual tooth profile projection curve on a projector, the error in the drawn standard curve may cause measurement errors.
For example, when measuring tooth profile error using the coordinate method on a universal tool microscope, the coordinate position error between the standard tooth profile and the actual tooth profile can cause tooth profile measurement error.
Reasons for errors caused by measurement operations
For example, there is an error in the focusing operation when measuring with a universal tool microscope, resulting in unclear images. Adjusting the position of the milling cutter tooth profile does not achieve optimal clarity of the tooth profile image, resulting in measurement errors.
1. For example, when measuring on a tool microscope, there is an error when using the line pressing method to aim, resulting in an error in the lateral reading, thereby causing tooth shape measurement error.
2. Another example is that due to unskilled measurement operations, there is a deviation when searching for the maximum point P of tooth profile deviation, which causes errors in tooth profile measurement calculation.
Pay attention to the above points in precision parts processing, which will greatly avoid measurement errors.
