“…Ultimately, the approach proposed in this article extends the Kline and DeVor's model [16] to the taking into account of great axial engagements. The integral relates to the deformation due to each elementary cutting edge length whereas, in the original model, the integral relates to the forces, the resultant forces being used to calculate the deformation.…”

“…Numerical model affords great flexibility in considering dynamic chip load variation or complex cutting edge geometry including runout effect. Kline et al [12] established an end milling force model through numerical integration of the local force with the lumped force model. This numerical force model has served as the basic framework for many other milling force models developed afterwards.…”

A space-time convolution approach to analyze the milling force for a general helical cutter is proposed. The single flute cutting force is firstly established through an integrated space-time convolution process. Subsequently, multi-flute milling forces are obtained through convolution integration in time domain (i.e., angular domain). In this convolution force model, convolution theorem does not apply directly and a modified convolution theorem is presented to find the Fourier coefficients of the total milling force for any analytically definable helical cutter. From the Fourier analysis, the magnitudes of higher order Fourier coefficients are shown to drop off quickly. Therefore, the capability to extract a small number of Fourier coefficients as characteristic values of milling forces is an important advantage of this convolution force model. Furthermore, this model provides a convenient means to calculate the Fourier coefficients of the milling forces if the profile of cutter/workpiece can not be analytically definable and only the discrete values of cutter/workpiece profile data are given from scanning. Also, the general effects of cutter geometry and cutting parameters on the spectra characteristics of the milling forces are extracted and discussed. Based on the spectra characteristics, the strategy of selecting cutters for rough and finish machining in slot milling is presented.

“…With this approximation, the undeformed chip thickness has been formulated with ease and expressed by many researchers as the radial distance between two consecutive circular tooth trajectories. For mechanistic cutting force modeling, this concept of undeformed chip thickness was first adopted for end milling by Kline et al [2]. This pioneering work was later extended to incorporate cutter runout and cutting system flexibility in the determination of chip thickness [3,4].…”

Accurate cutting force prediction is essential to precision machining operations as cutting force is a process variable that directly relates to machining quality and efficiency. This paper presents an improved mechanistic cutting force model for multi-axis ball-end milling. Multi-axis ballend milling is mainly used for sculptured surface machining where non-horizontal (upward and downward) and rotational cutting tool motions are common. Unlike the existing research studies, the present work attempts to explicitly consider the effect of the 3D cutting motions of the ballend mill on the cutting forces. The main feature of the present work is thus the proposed generalized concept of characterizing the undeformed chip thickness for 3D cutter movements. The proposed concept evaluates the undeformed chip thickness of an engaged cutting element in the principal normal direction of its 3D trochoidal trajectory. This concept is unique and it leads to the first cutting force model that specifically applies to non-horizontal and rotational cutting tool motions. The resulting cutting force model has been validated experimentally with extensive verification test cuts consisting of horizontal, non-horizontal, and rotational cutting motions of a ball-end mill.
