### Plunge Milling  
During plunge milling, a higher value of the F\({}_{\text{z}}\) force component was observed compared to the F\({}_{\text{x}}\) and F\({}_{\text{y}}\) components. However, this difference was smaller than in the case of high-feed milling. In Figure 9a, which shows the progression of the F\({}_{\text{z}}\) force component during cutting, the force values increased as the cutting-edge wear progressed, but this occurred less dynamically compared to high-feed milling. The F\({}_{\text{z}}\) force values increased in a manner closer to linear. In Figure 9b,c, which shows the progression of the F\({}_{\text{x}}\) and F\({}_{\text{y}}\) force components, the force values were independent of cutting-edge wear, but the values were higher than those observed in high-feed milling. The differences in results between trials can be attributed to measurement errors in the data-acquisition system, the dynamic nature of the process, and the short cutting-cycle time. Similar to high-feed milling, an analysis of cutting insert wear on both the rake face and flank face was conducted (Figure 10). The wear mechanism in plunge milling followed the same accelerated wear pattern as observed in high-feed milling. Micro-chipping was observed on the rake face, and the abrasive wear reached a value of up to 0.6 mm. This distance was measured by drawing a line perpendicular to the cutting edge. Micro-chipping was also found on the cutting edge itself, while abrasive wear on the flank face was observed, also reaching up to 0.6 mm.

Table 3: Summary results for high-feed milling with the ceramic CW100 insert. Based on the cutting-edge wear measurements, the volume of material predicted to be removed during the tool's life cycle (\(G_{\text{max}}\)) was calculated. The extrapolated volume of material that could be removed before reaching the cutting-edge wear limit was determined. Figure 11 shows the graph of V\({}_{\text{BB}}\) wear measured as a function of the volume of machined material, along with the trend line determined by a third-degree polynomial. In both
