Experimental milling moment model in orthogonal cutting condition: to an accurate energy balance

A 6-components mechanistic model of cutting forces and moments in milling

“…Studies have attempted to model cutting moments, such as Albert et al [15] who started to model the cutting moment phenomenology with orthogonal cutting tests in milling, or Cahuc et al [16] with turning tests. For the proposed model, the point of expression where the modelling is most relevant should be defined.…”

“…Authors [15,16] have developed models of the cutting moments for milling process and turning with vibrations. This works expressed the linear relations between moments and the chip section.…”

A 6-Components Mechanistic Model of Cutting Actions in Milling

“…Numerous orthogonal cutting tests carried out by Albert [6] have enabled initial interpretations of the cutting moment process phenomenology. An interesting result is the influence of the orthogonal parameters V c , f , a p on the preponderance of cutting moments.…”

“…This is why the development of cutting moments theory was a major step towards completing the cutting energy balance. This is the case of Albert [6] who started to highlight the cutting moment phenomenology with orthogonal cutting tests in milling. The objective of this paper is therefore to characterise the behaviour of 3D cutting, mainly that of the cutting moments, based on the work on cutting forces carried out in the literature.…”

“…To begin with, for a straight tool path, the theoretical trajectory described by the tool tip is trochoidal because it is composed of a circular motion related to the tool rotation as well as an axial feed rate to follow the imposed path (Figure 3). The most common model of the chip section is the normalized orthogonal chip section defined in the plane orthogonal to the cutting speed ⃗ V c [6,10]. It is defined as follows: This section actually corresponds to the chip section not yet deformed by the cutting, before the tool cuts the material.…”
