INVESTİGATİON OF THE EFFECT OF DRİLL GEOMETRY ON TOOL WEAR AND CHİP FORMATİON

Mehtap YAVUZ,  Harun GÖKÇE,  Ulvi ŞEKER, 

In this study, the effects of different drill geometries and cutting parameters on tool wear and chip formation forms are evaluated. It has been observed what parameters affect tool wear and chip formation form by making 100 test revolutions for 16 different combinations with different geometry sets and different cutting condition combinations. Experimental studies have used four different geometries, 10 mm diameter, two-spindle, helical, solid cementite carbide drill with original two-channel geometry developed with the common two-tool geometry commercially available and GGG 50 spherical graphite cast iron material as workpiece material. For experiment design, a Taguchi Test Design was created with three different control factors of four levels, geometric form of cutter, cutting speed and feed amount. When evaluating the test results, radial wear and outer wear are observed in all tools, but radial wear is generally increased with progressive increase.
