Abstract: The slitting method is a widely used semi-destructive technique for measuring residual stress. It comprises of machining an incremental slit in a specimen and measuring the strains that are relaxed due to machining process using a strain gage bonded to a region in the adjacent material. These strains are the used to estimate the residual stresses (RS). The aim of this work is to investigate the effect of spindle rotational speed applied during the slitting method for residual stress measurement. A Carbon/Epoxy (CE) composite is prepared using a manual layup technique at room temperature and post-cured at 90° C for 6 hours. The process-induced RS in the composite is determined using the slitting method with a cutter speed of 3000 rpm, 4000 rpm, and 5000 rpm. The results reveal that cutting speed has a very minimal effect on the obtained residual strains and corresponding RS until the depth of cut reaches 75 % of specimen thickness. [ABSTRACT FROM AUTHOR]
