Abstract: Studying chip's shape and size is an important part in carbon fibre reinforced polymer (CFRP) cutting technique as the generated chip's size and shape are closely linked to the chip generation process. In this present research work, an experimental analysis has been done to analyse the cutting depths' effect to the generated chip's shape and size. Five different cutting depths from 0.1 mm to 1 mm were used in the tests. A strong influence of cutting depth as well as fibre orientation to chip's shape and size was found. Apart from that, the answer of what is the minimum cutting depth below which a tool cannot cut the materials smoothly was studied. Four fibre orientations have been used separately; and the minimum cutting depth was studied at each fibre orientation. The results showed that the minimum cutting depth is not the same at each fibre orientation.
