This study investigates the effects of the scratching trajectory and the feed direction on the formation of ripple structure on the surface of polymer material using atomic force microscope (AFM) tip‐based nanomachining approach. Nanoscratching tests are carried out using a diamond AFM tip by single scanning method. Nine typical combining scratching trajectories and feed directions are illustrated. The stick‐slip and crack formation processes are used to explain the formation mechanism of the ripple structure for different scratching trajectories. The influence of the feed direction on the amplitude and period of the ripple structure is studied. In addition, the quality of the obtained ripple structure is also analysed.
