Edge Preparation

The article compares two cutting edge preparation methods and their influence on the machined surface roughness of the difficult to cut nickel alloy Inconel 718 and the tool wear of cutting inserts made of cemented carbide. The manufacturing and preparation process of cutting inserts used in the experiment were made by Dormer Pramet. The preparation methods used in the experiment were drag finishing and brushing. Cutting parameters did not change during the whole turning process to maintain the same conditions in each step of the process and were determined based on tests for a semi-finishing operation of the turning process. To obtain durability of 25 to 30 minutes with controlled development of the tool wear the cutting parameters were determined with cooperation with the cutting inserts manufacturer.

This article focuses on the analysis of tool wear mechanisms in milling of Inconel 718. Inconel 718 is tough and highly temperature resistive material, which is used due to its excellent properties especially in aggressive corrosive medium. Machining of this alloy is still complicated. The feasibility of four inserts tested for milling of Inconel 718 has been shown in the work. Different cutting speeds and feeds were used. Experimental tests were performed in order to analyze wear patterns evolution. It was found influence of cutting conditions and type if insert in tool wear mode.

There is considerable industrial significance to understand the nature of subsurface deformation under the machined surface for correct prediction of surface properties in machined components based upon the machined conditions and material behaviors that give rise to them. In this study, high speed machining of Inconel 718 was carried with whisker reinforced ceramic cutting tool under different conditions of tool wear, coolant state and cutting parameters. The objective of the present investigation was to determine the effect of both cutting parameters and tool wear on the plastic deformation in the subsurface region of Inconel 718 after the finishing machining with above process conditions. The surface and subsurface region of machined specimens were examined using a high resolution scan electron microscope (HRSEM) and EBSD technique, microhardness measurements were also conducted on the test samples, accordingly plastic strain analysis were carried out.

This paper presents a study of the quality of a surface roughness model for mild steel with coated carbide cutting tool on turning process. The experiments were carried out under wet and dry cutting conditions. The model is developed based on cutting speed, feed and depth of cut as the parameters of cutting process. This research applies the fractional factorial design of experiment approach to studied the influence of cutting parameters on surface roughness. The measured results were collected and analyzed using commercial software package called Minitab. Analysis of variances is used to examine the influence of turning factors and factor interactions on surface roughness. The result indicated that, there are inherent differences in surface roughness between wet and dry cutting process with the same parameters process model. Analysis of variance was found that feed parameter is the most significant cutting parameter, which influences the surface roughness. The most significant interactions were found between cutting speed and feed parameters for dry turning process. Therefore is a significant effect of using combination of the fluid for cooling the cutting operation.

Tool Wear Mechanism

WC–5TiC–10Co cemented carbides inserts were prepared and used for the cutting tool for HT250 gray cast iron. The objective was to investigate the wear mechanism when machining HT250 gray cast iron with WC–5TiC–10Co cemented carbides inserts. WC–10Co cemented carbides with the same sintering technology and grain size were prepared for comparison. wear mechanism was examined at the same cutting parameters. The cutting tests were performed at a speed of 120 m/min with feed rate of 0.2 mm/rev and a constant depth of cut of 0.2 mm under dry conditions. Tool wear mechanism is analyzed by SEM and EDS. Adhesive and built-up-edge were found to be the predominant tool wear for WC–5TiC–10Co cemented carbides inserts. However, Attrition was the main wear mechanisms observed in WC–10Co cutting tools. The results obtained indicated that WC–5TiC–10Co cutting tools performed better than WC–10Co cutting tools, in terms of tool wear with current parameters.
