Though controlling the radial depth of cut is one solution, the minimum depth of cut near the involute center is so small as the surface roughness, and the accuracy is not stable. In the present paper, the relationship among cutting area, tool contact length and cutting force is analyzed by the ple linear regression analysis, and the cutting force was simulated.

International Scholarly Research Notices

When the cutting tool is cutting a sample (a portion of the circumference of the work-piece being cut) with a small value of mean hardness, the magnitude of the cutting force drops. On the other hand, the cutting force jumps up when the cutting tool is meeting a sample with a large value of mean hardness.
