Abstract
This paper aims to identify the capability of a highly fexible industrial robot modifed with a high-speed machine spindle for drilling of aluminum 6061-T6. With a focus on drilling feed rate, spindle speed, and pecking cycle, the hole surface roughness and exit burr heights were investigated using t...
