Abstract: With ever-increasing demands for the development of modern industries, it also takes higher requirement for processing accuracy detection in large and medium sized industrial components. When a certain type of engine is measured, which has been relatively sophisticated in structures and larger in size, due to the special working environment, it is necessary to avoid laying cooperation marks on to-be-measured objects as much as possible. Thus practical researches need to be undertook upon this requirement, like return light test is carried out for cooperation marks and various types of setting complex distribution measuring points are designed. It is suggested in the test that measurement accuracy could be enormously improved by the way of adding measuring auxiliary surfaces, as the accuracy is not affected by decreasing half of the measuring points on measured objects. Lastly, the researches of the setting angles of measuring auxiliary surfaces and columnar-like measured objects are taken.
