“…Tool path machining programs are introduced by using these software while many forms, such as one-way, zigzag, spiral, etc., are proposed for the machining path. Selection of these methods affects also machining time and surface quality of the machined material [1][2][3].…”

“…Efficiency is reduced when the machining conditions are non-standard, even if the suitable tool is selected. Theoretical studies should be carried out for each material to be machined and each type of cutting tools in order to provide high efficiency and to be able to make economical machining [1,2,[6][7][8][9][10]. It is specified that determination and application of cutting tool strategies and movements are critical in milling of volume casts, aeronautical and cutting casts [1][2][3][4][5].…”

In this study, surface roughness and cutting forces were investigated experimentally in milling of Al 7075 material by DLC coated end-mill cutting tools. Effect of tool path, feed and cutting depths on surface roughness and cutting forces was examined. Taguchi technique was used for optimization of the milling process. Also, a variance analysis (ANOVA) was used for determination of effect of each parameter on the obtained results.In conclusion, the relationship between the dependent and the independent variables was modelled with regression analysis. Optimal machinability of Al 7075 material by DLC coated end-mill was determined in this study.

“…The forces are modelised as concentrated forces localised at the contact point between the tool and the part and finally a cantilever beam model is used for the calculation of the deflection. Some authors propose other combinations: Seo [2] and Law [13] use concentrated forces applied at the middle of E A , Kops [7] makes a comparison between cantilever beam modelisation and MEF, Ryu [12] takes into account the deformation of tool clamping parts thanks to concentrated longitudinal and rotational stiffness . Some drawbacks such as the lack of accuracy, the calculation time, the limitation to straight line make these methodologies not applicable in practice for interactive tool path generation.…”

In end milling of pockets, variable radial depth of cut is generally encountered as the end mill enters and exits the corner, which has a significant influence on the cutting forces and further affects the contour accuracy of the milled pockets. This paper proposes an approach for predicting the cutting forces in end milling of pockets. A mathematical model is presented to describe the geometric relationship between an end mill and the corner profile. The milling process of corners is discretized into a series of steady-state cutting processes, each with different radial depth of cut determined by the instantaneous position of the end mill relative to the workpiece. For the cutting force prediction, an analytical model of cutting forces for the steadystate machining conditions is introduced for each segmented process with given radial depth of cut. The predicted cutting forces can be calculated in terms of tool/workpiece geometry, cutting parameters and workpiece material properties, as well as the relative position of the tool to workpiece. Experiments of pocket milling are conducted for the verification of the proposed method.
