“…The second comparison (right side in Figure 12) presents the same type (IIb) and overlap (m) but with different engagement conditions, resulting in different cutting force profiles. This result confirms that the proposed formulations, as it is summarized in Table 3 for down-milling and Table 4 for upmilling, in a specific type and overlap combinations, include the potential occurrence of several points in the cutting force profile, but their presence depends on additional conditions Equations (18)(19)(20)(21). In summary, the experimental results show a good agreement with the proposed cut- In summary, the experimental results show a good agreement with the proposed cutting force shape classification.…”

“…However, quick analytical information about the expected cutting forces could be very useful in monitoring solutions (e.g., depth of cut identification [19], feed adjustment [20]). Indeed, measured cutting forces can return high-value information regarding the actual process, and, along with the expected cutting forces, they allow the process to be controlled by adjusting the cutting parameters [21].…”

“…The Equations ( 18) and ( 19) are valid for both down-milling and up-milling, while the others apply to either down-milling (20) or up-milling (21). Considering the cutting conditions and the type/degree of overlap combination, the key points representing the multiple flutes F shape in one period (from ϑ 1 to ϑ 1 + φ z in down-milling and from ϑ 4 − φ z to ϑ 4 in up-milling) are presented in Table 3 (down-milling) and Table 4 (up-milling).…”

In 3-axis milling, cutting force analysis represents one of the main methods to increase the quality and productivity of the process. In this context, cutting force shape gives information of both monitoring and prediction of the cutting process. However, the cutting force shape is not unique, and it changes according to the cutting strategy, tool geometry, and cutting parameters. This paper presents a comprehensive approach to predict and classify cutting force shapes in 3-axis milling operations. In detail, the proposed approach starts by classifying the cutting force shapes for a single fluted endmill (i.e., single flute force shape), and, considering how the single flute force shapes may overlap one another, it extends the classification to a general multiple-fluted endmill. Moreover, the method provides, through analytical equations, angles, and magnitude dimensionless parameters of each key point, describing each shape classified. Finally, the proposed approach was experimentally validated through several milling tests in different cutting conditions.

“…This significantly complicates the process of part manufacturing, which is unacceptable for mass production. In [30], the authors consider an even more complex system for suppressing parasitic vibrations by directly controlling the cutting force, which is also not acceptable in the practice of actual production.…”

The presented paper proposes a method of adaptive control of the metal cutting process based on the analysis and interpretation of recorded sound for the identification of the cutting process. The presented research results clearly demonstrated the efficiency of using the sound generated during cutting by CNC lathe 16 K20T1 for the adaptive metalworking control. The sound makes it possible to control the accuracy of the workpiece part geometry and the surface quality in the online mode. The online mode also makes it possible to make an informed decision about a timely interruption of the cutting process or the continuation of the process in the altered modes for its successful completion. As the research results presented in the paper show, there is a close correlation between the sound generated by cutting and the roughness of the surface being machined or the degree of wear of the cutting tool. The correlation between the sound and roughness of the machined surface is 0.94, whereas between the sound and wear of the cutting tool is 0.93. The paper aims to use the generated sound as operational information needed for adaptive control of the metal processing process and timely monitoring and diagnostics of the condition of processed materials using the precision index, newly introduced as the machining quality index.
