This paper aims to investigate the machining characteristics of surface ground by fixed abrasives. Face grinding experiments of aluminum block are done. Different surface in experiment are generated through change of processing time while keeping other experiment parameters unchanged, and those tests of surface strain and roughness of aluminum blocks are conducted. The magnitude of stress and roughness on sample after experiment increases with processing time, which is also fit for the change of the above index parameter between before and after experiment. Larger surface stress of sample on which higher surface roughness is also seen is found in present investigation. The most helpful findings in experiments indict that engineering in workshops will get the method to achieve the product with high performance, when decreasing the surface stress and roughness and extending service life.
