Turning Insert Chip Former Geometry for Soft Chip Formation

The patent applies local quality by creating a specific elevated bottom surface geometry in the chip former with different levels and slopes. The chip former includes a first bottom surface, a second bottom surface elevated relative to the first, and a third bottom surface elevated relative to the second, with specific slope requirements (greater than 45 degrees). This localized geometric variation in the chip former structure creates conditions for soft chip formation in specific regions while maintaining overall chip control functionality.

The patent employs curvature principles by designing the chip former with multiple elevated surfaces and slopes greater than 45 degrees, creating a three-dimensional curved geometry that guides chip flow. The elevated bottom surfaces with steep slopes create a curved path for the chip, increasing the radius of curvature and transforming the chip shape from hard and compact to soft and elongated, thereby reducing deformation forces.

The patent applies segmentation by dividing the chip former bottom surface into three distinct levels: a first bottom surface, a second bottom surface elevated relative to the first, and a third bottom surface elevated relative to the second. Each segment serves a specific function in guiding and controlling the chip flow at different stages of formation. This segmented approach allows for precise chip control while maintaining a systematic and manufacturable geometry.

The patent utilizes parameter changes by specifying precise geometric parameters for the elevated surfaces, including slope angles greater than 45 degrees and specific elevation relationships between surfaces. By controlling these geometric parameters, the patent achieves effective chip control and soft chip formation without requiring overly complex structures, as the effectiveness is driven by specific parameter ranges rather than intricate geometries.
