Spindle Accuracy Test multi-turn data acquisition and processing

min as an example test results. Figure 8,9,1011 were collected l,[link widoczny dla zalogowanych], 2,4,8 circle drawn with the data spectrum and circular images. Patterns show that: the larger the amplitude of the low sub-band - can not be ignored. 2,48 images showed clouds circle round ring, and its reproducibility is not good. The roundness value with increase of indiscriminately Xi decreases when the number of turns enough, to a stable value. At this point the value of roundness measuring machine can be used to cut in ideal conditions, can be processed roundness and surface roughness of 53 fur shame RANGEYALUEPREQUENGY (a) Figure 8l0um '∞ = 7u | n \Draw a circle image, we should note that on the basis of radius.

Error of 6 large bass, but when R increases to a certain value l, 6 stabilized. Therefore, when assessing the error. To reasonably select the month. One by one device ...
