WebAug 2, 2024 · This impact intensified chip curling. It resulted in the more chip bending and more critical strain causing chip breakage. 3. 15 to 20% reduction in surface roughness was observed when ultrasonic vibration has been added. In one side, less variation in force generation (more stability) during UD was mentioned as a reason of roughness reduction. WebN2 - Chip-form/chip-breakability and tool-wear/tool-life are two important aspects commonly considered in evaluating the performance of a machining process. The advent of new grooved tools with complex chip-groove geometry has required a better understanding of the curling behavior of the chip for effective curling and breaking of the chip.
