ANALYSIS OF DRILLING PARAMETERS IN AIRCRAFT STRUCTURES

This work aims to study the drilling dry process in the aircraft structures. In the first stage were used helical speed steel drills with different geometries. This was used various combinations of cutting parameters. The power cut was monitored by sensors connected to the machine tool. The burr were measured and evaluated in accordance with the terms of cut. The structure deformation and the roundness of the holes were evaluated. Based on preliminary results, there is a need to replace the process of drilling using drills by helical interpolation milling. The second stage was used the same method of evaluation.
