This experimental study investigated the effects of milling conditions on the finished surface roughness. With four controllable factors-three levels (cutting velocity, feedrate, radial depth of cut, and cutter helix angle), the nineteen experiments were performed with performance measurements of surface roughness. | Influence of different cutter helix angle and cutting condition on surface roughness during end-milling of c45 steel International Journal of Mechanical Engineering and Technology IJMET Volume 10 Issue 03 March 2019 pp. 1275 1284 Article ID IJMET_10_03_130 Available online at http ijmet JType IJMET amp VType 10 amp IType 3 ISSN Print 0976-6340 and ISSN Online 0976-6359 IAEME Publication Scopus Indexed INFLUENCE OF DIFFERENT CUTTER HELIX ANGLE AND CUTTING CONDITION ON SURFACE ROUGHNESS DURING END- MILLING OF C45 STEEL Dung Hoang Tien Hanoi University of Industry Vietnam Nhu -Tung Nguyen Hanoi University of Industry Vietnam Trung Do Duc Hanoi University of Industry Vietnam Corresponding Author ABSTRACT This experimental study investigated the effects of milling conditions on the finished surface roughness. With four controllable factors-three levels cutting velocity feedrate radial depth of cut and cutter helix angle the nineteen experiments were performed with performance measurements of surface roughness. By ANOVA analysis the effect of cutting conditions on the surface roughness were analyzed and modeled. The most suitable regression of surface roughness was a quadratic regression with the confidence level is more than 97 and this model was successfully verified by experimental results with very promising results. Besides by using ANOVA method the optimization process of surface roughness was performed. The optimum value of surface roughness is μm that was obtained at cutting velocity of m min a feedrate of mm flute at a radial depth of cut of mm and a cutter helix angle of 45o. The approach method of the present study can be applied in industrial machining to improve the surface quality in finished face milling the C45 Steel.
