    In this research, a one-way abrasive flow machining (AFM) was sketched and built, and the impact of temperature on surface roughness (Ra) values and material removal rate (MRR) before and after each test have been investigated considering the SiC. Al2O3, and B2O3 particles as abrasive particles. The abrasive particles were dispersed at 35 wt.% in the prepared media. The findings revealed that the media containing Al2O3 abrasive particles had higher surface roughness compared to the SiC and B2O3 particles. The maximum variation of surface roughness for SiC, Al2O3, and B2O3 particles was observed at −196 °C, which was 2.991, 2.588, and 1.684, respectively. In addition, the material removal rate values decreased for all the prepared samples as the temperature was reduced. At lower temperatures, lower material removal rate values were recorded since the viscosity of the abrasive paste increased. Display omitted •Temperature efficacy on surface roughness and material removal rate were analyzed.•Comparison between SiC, Al2O3, and B2O3 particles as abrasive particle was investigated.•The SEM morphologies of the worn surfaces represented that abrasive particles caused finer surfaces.•Media containing Al2O3 abrasive particles had higher surface roughness.•Material removal rates decreased with the temperature decrement.
