In this paper, dry turning operation was carried out on four types of workpiece materials SCM420, SCM420H, SCM440 and SM45C in order to review the effect of cutting parameters on surface roughness (Ra) and resulting cutting force (F). The turning operation was conducted on the NC lathe with the CVD coated carbide inserts. The analysis of variance (ANOVA), linear regression model and main effect plot for mean were employed to investigate the correlation between responses (Ra and F) and cutting parameters. The predictive equations showed a satisfactory correlation with high coefficients of determination (R2) from 80.76 to 98.89%. The lowest feed rate and highest spindle speed were applied to minimize surface roughness, but both were performed at level 1 to minimize the resulting cutting force. The optimal experimental conditions showed the brilliant results as the surface roughness 1 μm and resulting cutting force 39.92 N. The SCM440 steel indicated the best surface roughness responses followed by SCM420, SCM420H and SM45C steel. The SCM440 steel revealed the lowest resulting cutting force followed by SCM420, SM45C and SCM420H steel.

Due to environmental concerns and the coming legislations, pollution-free and eco-friendly minimum quantity lubrication (MQL) technology has become focus of attention in manufacture field. The MQL and cooling system in this work has been designed, fabricated and used. The cutting performance of MQL with cooling air compare with the conventional cooling method in milling of GH4169 aerospace superalloy is evaluated based on analysis of cutting force and surface finish. The effect of cutting parameters (depth of cut, feed rate) on machining performances is analyzed. The experimental results show that, the application of MQL and cooling air brings about a lower cutting force, better surface finish compared to conventional coolant environment.

Aisi 316

The effects of different cutting parameters, insert nose radius, cutting speed and feed rates on the surface quality of the stainless steel to be use in medical application. Stainless steel AISI 316 had been machined with three different nose radiuses (0.4 mm 0.8 mm, and 1.2mm), three different cutting speeds (100, 130, 170 m/min) and feed rates (0.1, 0.125, 0.16 mm/rev) while depth of cut keep constant at (0.4 mm). It is seen that the insert nose radius, feed rates, and cutting speed have different effect on the surface roughness. The minimum average surface roughness (0.225µm) has been measured using the nose radius insert (1.2 mm) at lowest feed rate (0.1 mm/rev). The highest surface roughness (1.838µm) has been measured with nose radius insert (0.4 mm) at highest feed rate (0.16 mm/rev). The analysis of ANOVA showed the cutting speed is not dominant in processing for the fine surface finish compared with feed rate and nose radius. Conclusion, surface roughness is decreasing with decreasing of the feed rate. High nose radius produce better surface finish than small nose radius because of the maximum uncut chip thickness decreases with increase of nose radius.

This paper offers an experimental study of the microcutting mechanisms in marble grinding to aid the optimization of the marble grinding process. The necessity for investigating these mechanisms is dictated by the increased use of marble in many applications and the fact that grinding and polishing processes are the dominant technologies used to meet surface finish requirements in this natural material. The experiments are aimed at the determination of the normal component of the cutting force and of the grain traces in microcutting with a single diamond grain. The investigations carried out make provisions for establishing critical grain penetration and cutting depths and allow the prediction of the normal cutting force component as a function of grain penetration speed and depth.

Rough Turning

In this paper, the cutting experiment was used to study the influence of various cutting parameters on cutting force when rough turning titanium alloy (TC4) with the whole CBN tool. The results indicate that among the cutting speed, feed rate and cutting depth, the influence of the cutting depth is the most significant on cutting force; the next is the feed rate and the cutting speed is at least.
