ABSTRACT
Mechanical processing of materials based on aluminum is accompanied by defects on the surface (Kovensky et al. 2001), resulting from the cutter, as well as sticking of the deleted material on the cutting edge of the tool, which causes reduction in the efficiency of the cutting process and increases the temperature in zone cutting and tool wear. To achieve a high surface quality during the cutting of silumin, the use of the special cutting instrument with adamant-like carbon coating and other wearresistant coatings is recommended. In this case, the cutting tool must have a large front corner, the small rounding radius of the cutting edge ρ and the small tool apex radius r. In some cases, thin walled sleeves are processed to increase the cooling reasonably to use the lubricant-cooling agent. Also, to reduce roughness, a chemical agent may be added to the lubricant-cooling agent, which will lower the strength of the layer of the removed material. Thus, anodic machining of silumin using the caustic soda solution allows us to obtain the surface roughness Ra of 0.6-0.7, the cutting speed V = 214 m/min, the cutting feed S = 0,05 mm and the cutting depth t = 0,5 mm. A cutting tool uses a replaceable insert of the cup shape, made of cemented carbide. In the capacity of cutting tool, the replaceable carbide like plating form is used.
