Original abstract

Optimization of the metal drilling process requires creation of minimum amount of burrs and uniform appearance of the drilled holes. In this paper, an experimental investigation was performed on 2 mm sheets of wrought aluminium alloy Al99.7Mg0.5Cu-H24, using 1.6 and 2 mm diameter drills. Cutting data, clamping conditions, and drill geometry were varied in order to optimize the process and reach the desired quality. The results revealed possible reduction of burr occurrence on both the entry and exit side of the sheet, requiring no additional deburring. The demand on the uniform appearance of drilled holes was fulfilled as well as high productivity achieved. Such optimized process results in a noticeable production cost reduction.

Czech abstract

Optimalizace vrtacího procesu si žádá tvorbu minimálních otřepů a jednotný vzhled vrtaných děr. V tomto článku experimantální práce zahrnují vrtání plechů tloušťky 2mm z tvářené slitiny l99.7Mg0.5Cu-H24 vrtáky průměrů 1,6 a 2 mm. Pro optimalizaci procesu se měnily řezné podmínky, upínání a geometrie nástrojů, aby se dosáhlo požadované kvality děr. Dosažené výsledky prokázaly výraznou redukci otřepů bez potřeby dalšího odjehlování, což přinášá další úspory ve výrobních nákladech.
