This study presents the investigation of abrasive wear performances for polyamides using a Response Surface Methodology (RSM). Tests were carried out in a pin-on-disc using various conditions against SiC abrasive cloth. Box-Behnken Design of RSM was adopted to study the effect of control factors like load, speed and tensile strength of the tested samples on the volumetric wear rate. The experimental results indicated that the volumetric wear rate increased with increasing load, speed and decreased with increasing the tensile strength, but material property was more effective than other factors. Furthermore, the results of analysis of variance showed that tensile strength was predominant factor on the abrasive wear rate, followed by load and spindle speed. The contributions of tensile strength, load and speed were about 33.55 %, 24.45 % and 21.87 %, respectively, while the contribution of square and 2-way of interaction was about 3.04 % and 11.23 %, respectively.
