Abrasive flow rotary machining is a new form of abrasive flow machining process which has been recently introduced by the authors as one of the non-conventional finishing and polishing methods. Since in abrasive flow machining process, the negative impact of temperature increase of the abrasive paste has been reported on the material removal rate, in this study the role of this parameter has been evaluated on the abrasive flow rotary machining. For this purpose, a new tool equipped with pressure and temperature measuring instruments as well as temperature control device has been designed and fabricated and the temperature changes of the abrasive paste during the process are measured. The process variables, in this case, have been selected based on the optimum machining conditions corresponding with the maximum material removal rate from the previous study of the authors. The experimental results with the new tool show that material removal rate and surface finish of abrasive flow machining are obtainable by abrasive flow rotary machining process. Also, no significant increase in paste temperature occurs in the abrasive flow rotary machining process during effective machining time intervals which is one of the advantages of abrasive flow rotary machining. In case of continuing the process, the material removal rate decreases by increasing the temperature of the paste, which shows similar behavior to the abrasive flow machining process.
