초록

In this study, we carried out interrupted cutting of carbon steel for machine structure(SM20C) withuncoated carbide tool and analyzed anova test and confidence interval to find influential factor to surfaceroughness, and obtained regression equation. Rhe results are follows: First, we found that affected factorto surface roughness in interrupted cutting was feed rate. Secondly, the cutting speed and depth of cutwas small affected to surface roughness. Finally, from multi-regression analysis of interrupted cuttingexperimental result, obtained regression equation and it’s coefficient determination was 0.814 and itmeans that regression equation was predictable. Compared with other continuous cutting, if feed rateincrease, surface roughness will grow in interrupted cutting.
