What is the "principle error" and how does it affect the machining accuracy of the part?
For example, the profiling of the gear, involute tooth profile on the existence of the principle of error, relatively speaking, compared with the Fan Chengfa gears with a large number of gears.
When the gear accuracy is not demanding, the processing capacity is very small, the processing cost is low, do not need expensive gear processing machine, just ordinary milling machine can complete the processing advantages, especially highlighted.
However, there is a principle of error processing, is conditional, there are advantages.
Does not meet the geometric shape of the principle of processing error, is the principle of error.
