| Summary: | A production facility model to be used und er the deep - hole drilling of large - diameter tube plates with a heterogen eous structure made of hard - to - machine materials is presented. Dynamic properties of the object as a composite membrane with several anchorage points are analyzed. Modes of the workpie ce vibrations with account for its i nternal heterogeneous structural features are defined. The object structure transformation in the cou rse of pr ocessing (the formation of a large number of holes) effects on its elastic and dynamic properties. Su ch effect fe atures are considered. To simplify the practical application of the model, some recommendations for t he global stif fness matrix transformation, and the production facility dissipation to the local points correspondin g to the applic ation places under the hole making are given. The research results are focused on the creation of an automatic co ntrol system for the deep - hole drilling of hard - to - machine and heterogeneous materials. |
