Experimental and numerical studies on chip formation

Then a milling tool with single abrasive grain and an experimental system for milling tools were developed to verify the numerical results. Also, the working process was recorded by a high-speed camera to analyze the chip formation mechanism and the thermal field was obtained by the 2D numerical simulation model to improve service life.

Wear Mechanism of Cemented Carbide Tool in High Speed

Dec 05, 2018· 3.1 Tool Wear. Many studies [21, 22] show that adhesive wear is the dominant factor of tool failure in cutting stainless steels with cemented carbide tools.In the milling process of 0Cr13Ni4Mo, the cutting temperature can reach 800 °C and the cutting force is also high. There is microscopic asperity on the rake face, and the tool’s hardness is decreased due to

Investigation on the Tool Wear Suppression Mechanism in

Excessive tool wear during hard and brittle material processing severely influences cutting performance. As one of the advanced machining technologies, vibration-assisted micro milling adds high-frequency small amplitude vibration on a micro milling tool or workpiece to improve cutting performance, especially for hard and brittle materials. In this paper, the tool wear suppression mechanism in
