dcterms:description
In the paper the long term tests results of twist drill cutting life are summed up. The were tested drills were made from improved high speed steel in two versions – HSS uncoated and HSS Co coated by PVD process with TiN. On basis of these tests the cutting conditions optimizations were calculated for the minimum machining costs criterion using the basic economic indexes of the workshop. It was determined, that the use of more expensive HSS Co drills coated with TiN with longer cutting life yielded lower total production costs than the use of uncoated HSS drills. These lower costs were reached at higher cutting speed. In the paper the long term tests results of twist drill cutting life are summed up.
