Experiment & Research of Boring Coordinate of Small Bore

According to the problems that occurs while the small bore diameter working in the nickel steel component,the influnce of the cutting tool's geometrical parameter,the cutting output and the length of the suspension to the wear of the boring cutter's measurement and the roughness coefficient of the working surface are discussed. The mathematical equation between the boring cutter measurement wear h and the geometrical parameter of cutting tool,and the mathematrical equation among the measurement wear,the cutting output and the length of the suspension as well are obtained to be used in choosing the geometrical parameter of the cutting tool,cutting output and analyzing the precision of the boring unit.
