The cutting edge of any tool is subjected to heat and pressure. Cutting process, the workpiece material close to the cutting edge at the same time, the first cutting edge in the main knife. Then, after the main cutting edge, the rake face plays the main role in the flow of iron chips. Auxiliary shear surface for large amount of energy transfer. In turning of steel parts, the resultant force is large(400~3,100 N/mm2, depending on the type of steel) and the temperature is high (up to 1,000 degrees Celsius). It is in the iron chip flow area that the ability of the tool material is tested to determine the main impact of the machining operation.
The tool material combination of the chip edge groove and the chip breaking groove on the indexable insert at a short distance along the edge line determines the shear stress effect, because the chip load on the entire surface is concentrated, and then takes away most of the heat generated during processing. Friction is a major factor, so the iron contact surface and the texture of the blade surface play an important role in performance.
The wear mechanism of the iron chip flow zone in steel processing is mainly chemical melting, and there is a tendency of partial plastic deformation. Diffusion wear is the main feature of high-speed cutting, and there is also abrasive wear, which mainly occurs in the gap surface of the blade, and these wear are continuous and controllable. Steel turning must be continuous and controllable wear, such as the main plastic deformation, hot cracking and groove wear.
