Wear mode of AISI 316 stainless steel

Wear mode of AISI 316 stainless steel

Side wear is the development of grooves at the cutting depth of both sides of the tool. This may be due to severe (hard or oxidized) parts on the machined surface. This is because the original working surface is more serious than the previous work hardening and internal material wear. It is observed that side wear is a failure mode during cutting experiments.

This model is obviously visible under the conditions of two maximum cutting speeds (205 and 261) m / min and low feed (0.02 mm / Rev) used in this study. However, this failure is due to the work hardening effect on the workpiece surface resulting from low feed rate. On the tool surface, the crater wears out shallow grooves in some areas. This pattern indicates that tool materials are spreading to the chip. It produces very high temperature on the surface of the cutter, especially in the absence of a coolant. The test crater wear will continue to rise until the cutting edge is broken or broken. Another obvious common side wear is the BUE caused by the low surface weight per minute or the poor shearing effect of workpiece materials. As the workpiece material sometimes adsorbs onto the blade or its coating, the workpiece material adheres to the surface of the tool, resulting in fragmentation of the cutting edge of the tool.
