Essay

The process of through holes drilling is an object of the research work. A mathematical model to discover the nature of feed changes depending on the diameter of the drill is proposed. The dependencies are developed to determine the elastic-plastic zone under the top of the drill before exit from the work piece body. Experimental study of kinematic accuracy and rigidity of vertical drilling machines are performed. The design of feed mechanism and through holes drilling devices is developed. The engineering technique to estimate the efficiency of the through holes drilling with feed regulation is proposed. Field of study is engineering and machining of metals.
