This article presents selected issues related to the workpiece surface quality after machining by the laser sintering of AlSi10MG alloy powder. The surfaces of the workpiece were prepared and machined by longitudinal turning with tools made of sintered carbides. The occurrence of breaches on the machined material surface was found, which negatively influence the values of 3D surface roughness parameters. The occurring phenomena were analyzed and proposals for their explanation were made. Guidelines for the machining of workpieces achieved by the laser sintering of powders were developed. The lowest value of the 3D roughness parameters was obtained for f = 0.06 mm/rev, ap = 0.5–1.0 mm, and for the nose radius of cutting insert rε = 0.8 mm. The results of research on the effect of cutting parameters on the values of parameters describing the surface quality are presented. Topography measurements and 3D surface roughness parameters are presented, as well as the results of a microscopic 3D surface analysis. Taguchi’s method was used in the research methodology.

Machining of materials by super hard tool like PCBN is to reduce tool wear to obtain dimensional accuracy, smooth surface and more number of parts per cutting edge. Wear of tools inevitable due to rubbing action between work material and tool edge. However, the tool wear can be minimized by using super hard tools by enhancing the strength of the cutting inserts. Extensive study has been conducted in the past to optimize the process parameters in any machining process to have the best product. Current investigation on turning process is a Taguchi optimization technique applied on the most effective process parameters i.e. feed, cutting speed and depth of cut while machining the work piece with tool. The experiments were carried out by a CNC lathe, using PCBN tool for the machining of EN 353 steel. The Taguchi technique and ANOVA were used to obtain optimal Turning parameters in the Turning of SS420 under wet conditions. The optimal factor for Surface Roughness-A1(Speed-1500)B2(Feed-0.04)C3(DOC-0.75), Machining Timing-A1(Speed-1500)B2(Feed 0.04)C3(DOC 0.75), Material Removal Rate-A2(Speed-1750)B1(Feed 0.02)C3(DOC 0.75). The Percentage of contribution for each Process parameter is Surface Roughness-Speed 38.59%, Machining Timing-Speed 35.98%, Material Removal Rate-Feed 29.83%.

Turning of sintered carbide parts has not been a common theme in the literature such as the case of other hardened materials. This is a statement made on the basis of recent research on this subject in which journals and conference proceedings were consulted. However, cutting of sintered cemented carbide parts, especially the turning operation, is an important task for a large number of applications where the typical properties of these materials are required. Therefore, the aim of this research was to carry out internal turning experiments in the manufacture of sintered cemented carbide dies used to forge beer cans. The focus of the experiments was to measure and analyze the workpiece surface roughness and wear of cutting edges used in internal turning process. Therefore, samples of sintered cemented carbide WC-Co (12% Co) were submitted to internal turning process with PCD insert tool. Cutting speed and feed rate were used as input variables in the experiments. It was found that, neither very low cutting speeds, nor high feeds can be used to avoid early breakage of the tool. Moreover, for the experiments where no early tool breakage occurred, the increase of feed caused the number of cutting passes prior to the cutting edge breakage to decrease and the workpiece surface roughness to increase. The experiments performed in this work confirm that sintered cemented carbide internal turning, besides being viable, is also feasible to be used to replace grinding operations, at least in terms of surface quality obtained.
