Influence of Machining Parameters on Cutting and Chip-Formation Process during Cortical Bone Orthogonal Machining
Cortical bone machining is commonly used in craniofacial surgery. The shaping of bone surfaces requires a precise determination of the process’s complexity due to the cutting tool’s defined or undefined geometry. Therefore, research was carried out to assess the impact of the rake angle (<i>γ&...

| description | Cortical bone machining is commonly used in craniofacial surgery. The shaping of bone surfaces requires a precise determination of the process’s complexity due to the cutting tool’s defined or undefined geometry. Therefore, research was carried out to assess the impact of the rake angle (<i>γ</i>), clearance angle and depth of cut (<i>d</i>) on the cortical bone machining process. Analysis was carried out based on the orthogonal cutting in three directions. The cutting tool shape was simplified, and the cutting forces and the chip-formation process were monitored. The highest values of the resultant cutting force and shear force were recorded for <i>γ</i> < 0. The specific cutting force decreases with the increase of <i>d</i>. Cutting in the transverse direction is characterized by the highest values of resultant cutting force and shear force. The coefficient of friction depends primarily on the <i>d</i> and takes a constant value or increases with the increase of <i>γ</i>. The tests showed that the chips are formed in the entire range of <i>d</i> ≥ 0.5 µm and create regular shapes for <i>d</i> ≥ 10 µm. The research novelty confirms that even negative cutting angles guarantee controlled cutting and can find wider application in surgical procedures. |
