Investigatıon of the Effect of Built-Up Edge on Chip Morphology at the Cutting Edge During Turning Operation

Investigating the mechanism of Built-Up Edge (BUE) formation, which increases tool wear and leads to a decrease in surface quality and tool life, is a critical aspect in engineering applications. A detailed examination of this mechanism holds great importance for extending tool life, reducing workpiece surface roughness, and ultimately lowering tool and production costs. Currently, theoretical, experimental, and numerical studies on this formation mechanism are still ongoing. In this research, the effects of cutting speed on the BUE formation mechanism and the resulting chip morphology were examined in detail, while keeping the cutting depth and feed rate constant. Experimental studies have shown that cutting speed directly influences the formation of BUE and the resulting chip morphology. The extent of this effect, along with details related to chip morphology and BUE formation, was analyzed by comparing scanning electron microscope images. Additionally, the relationship between cutting force values read from the machine monitor during cutting and cutting speed was also investigated. This research highlights the potential to achieve a longer tool life, high-quality workpiece surfaces, and cost-effective production through the optimization of parameters in the workpiece machining process
