The focus of pure basic level is how to reduce the error and improve the accuracy. Therefore, the basic principles of selecting essential surface are as follows:
First, the principle of datum coincidence. As far as possible, the design datum should be selected as the positioning datum. Especially in the final completion, to ensure accuracy, we should pay more attention to this principle. In this way, position error and datum deviation can be avoided;
Second, the principle of the unification of benchmarks. Various surface treatments should be selected to ensure the position accuracy of each surface as far as possible; sometimes, the principle of common datum should be followed for repeated processing;
Third, the principle of self reference. Some small machining allowance and unified finishing process ensure machining quality and productivity, with precision machining surface itself as a basic level.
