ABSTRACT

The effect of cutting conditions such as numbers of tool teeth, depth of cut and cutting speed on the cutting resistance about 12%Cr steel hasn't been studied before. So the effect of cutting conditions on the cutting resistance will be investigated in this paper. The relationship between cutting resistance and work damaged layer will be taken into consideration. The results are as follows. (1)The cutting resistance becomes larger with the increase of the depth of cut and the numbers of tool teeth. It has no relation with cutting speed. (2)The depth of work damaged layer increase with the increase of the depth of cut and numbers of tool teeth. It does not change with the increase of cutting speed. (3)The deformation of cutting surface becomes larger with the increasing depth and numbers of tool teeth. It changes a little with the increase of cutting speed. (4)It was found that the depth of work damaged layer increased with the increase of the cutting resistance. The depth of work damaged layer is thought to have an intimate relation with the cutting resistance. (5)The experimental value for work damaged layer by hardness measuring is thought to be reasonable value, because the experimental value is nearly equal to the evaluated one obtained from Sokolovskii's stress equation.
