Abstract

The research aims to improve performance of high-accuracy hole-making in hybrid stacks. The stacks consist of carbon fiber reinforced plastic and Titanium and Aluminum alloys. Holes were made with Atlas Copco PFD-1500, a pneumatic drilling machine with automatic tool feeding. A MAPAL hard-alloy six-toothed reamer with MQL channels was used as a cutting tool. Hole diameters were controlled using Carl Zeiss CONTURA G2. Cutting parameters’ variation ranges were identified and the experiment was designed in Statistica 6. The experiment design involves two factors (cutting speed, feed) and an additional block factor describing a reaming allowance. As a result, multi-factor regression analysis models were developed. They describe the effects of cutting parameters on the hole accuracy in hybrid stacks. The cutting parameters were optimized and recommendations were given.
