System of machining using computer-aided design of three-tooth drills

Abstract

Three-tooth drills have been used relatively recently. However, even now their application gives an important technical result. Increase processing performance up to 2-3 times. In this regard, the article proposes a new approach to the automated design of teeth of drills with a special shape of the front surface machining by laser ablation. The system is based on fast interpolation splines, allowing continuous control of the laser ablation machine and thus greatly improving the processing efficiency. The proposed tool designs are equipped with an ordered microtexture on the front surface with a uniform distribution applied normally to the cutting edge of the drill in the sharpening area. The results of setting the shape of the front surface are the basis for the technological preparation of applying a microtexture using laser ablation machine

Computer-aided design system for a drill with an improved shape of the flunk surface

“…To implement the search for the shapes of cutting edges when intersecting helical surfaces by specifying a geometric shape based on the main parameters of the flute (core, angle of wedge, etc. ), it is preferable to familiarize yourself with the results presented in [14][15][16][17][18][19][20] or with a set of points of the helical flute specified numerically by reading the approaches from studies [21,22].…”
