Unified cutting force model for turning, boring, drilling and milling operations

A study on estimation of 3-dimensional surface roughness of boring processes including kinematic motion deviations

“…There are various inserted tool tip geometries are used in the cutting tools, and seventeen inserted tool tip shapes are defined in ISO 13399 standards (Kaymakci et al 2012). The generalized geometric model of the inserted tools is shown in Fig.…”

“…The geometry of the tool tips are defined in their local coordinate system O T analytically. The control points are derived as functions of insert parameters that have been adapted from Kaymakci et al (2012). …”

“…The three dimensional cutting forces are also estimated for the cases of the insert boring heads with run-out. Kaymakci et al (2012) have proposed a unified cutting force model for turning, boring, drilling and milling operations with the inserted tools. The inserted tool tips and their orientations to the reference tool coordinates are mathematically represented by ISO tool definition standards.…”

Effect of Nominal Chip Thickness on Stability of Interrupted Turning

“…The oblique transformation method is most useful when modeling solid tools with continuously varying edge and chip geometry [10]. A unified geometric, kinematic, and mechanic model was proposed which allows the prediction of chatter stability for multiple machining operations with defined cutting edges by Altintas et al [11,12]. A novel dynamic cutting force model is proposed by Li et al [13], in which the cutting mechanism and the cutting force contribution on both the peripheral and the front cutting edges are taken into consideration simultaneously.…”

“…It is worth noting that, in the above studies [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16][17][18][19], dynamic cutting forces are only the function of dynamic chip thickness, and cutting force versus unit of dynamic chip thickness must be unique. However as shown in Figure 1, cutting forces versus the same dynamic chip thickness (Δℎ 1 = Δℎ 2 ) are unequal at different nominal chip thickness (Δ 1 ̸ = Δ 2 ), due to the fact that the nominal chip thickness is neglected.…”
