| In order to study the cutting force and surface roughness of H13 steel during hard turning, the single factor test and multi factor orthogonal test were
designed for turning test. The test results were analyzed by the range analysis method to study the influence of different cutting speed, feed rate and back cutting depth on cutting force and
surface roughness of the workpiece. The variation of cutting force and surface roughness were compared, the results show that the significant parameters affecting the cutting force were as
follows: back cutting depth>feeding rate>cutting speed. the significant parameters affecting the surface roughness of the workpiece were as follows: feeding rate>cutting speed>back cutting
depth. It is suggested from the single factor test analysis that the cutting force has a certain correlation with the change of surface roughness, and the change trend of surface roughness is
consistent with the cutting force. |
