“…Hence, trochoidal milling is only used to machine a narrow area of a workpiece. Second, the end-milling cutter that conducts trochoidal milling has a long tool life [12,13]. In the milling-milling machining method, many end-milling cutters complete the machining of a workpiece in an orderly manner; thus, tool life in the milling-milling machining method is longer than that in trochoidal milling when the total amount of wear in all endmilling cutters is averaged.…”

We proposed a new processing method to reduce the cutting force of the machining process effectively, as well as to improve tool life and machining process efficiency. The proposed method, called the milling-milling machining method, is a new form of composite machining that is similar to the turn-milling method. It combines the advantages of face milling and helical end-milling cutters and uses the synthesis motion of these kinds of cutters to complete surface processing. This technique effectively reduces cutting force and, thus, improves tool life and machining efficiency. The millingmilling machining method has the advantages of a large diameter face mill with a large milling area, a low cutting force, a stable and highly efficient cutting process that is similar to that of a helical end-milling cutter, and trochoidal milling. The outstanding characteristics of face milling and helical end-milling cutters can be applied directly to the milling-milling machining method. In addition, the proposed method has unique features. The up-down milling-milling machining method can offset a portion of the cutting forces. Apart from proposing the theory for the milling-milling machining method, we also designed new equipment, namely the planetary cutter, milling-milling driving head, and a computer numerically controlled milling-milling machine. We compared the proposed method and the common face milling method from the perspective of cutting forces. Experimental results show that the milling-milling machining method considerably reduces cutting forces compared with conventional methods.

“…Furthermore, the high aspect ratios of the complex geometries require the usage of tools with long shafts and small diameters, which restrains the process velocities even more. For milling such components, several different strategies have been used in the past [9,10]. However, to provide an economic process, the realization of high material removal rates at acceptable tooling costs is necessary.…”

“…Circular milling (also: trochoidal milling) is a machining strategy that takes advantage of the beneficial aspects of flank milling even for closed slots. This strategy also provides the milling of complex geometries as presented in Figure 1 and has shown to be favourable for milling advanced materials [10,12,13]. The most simple case of trochoidal milling is described in Figure 2(b), a straight slot with a constant width and parallel walls.…”

Advanced materials, like nickel-based alloys, gain importance in turbomachinery manufacturing, where creating complex surfaces constitute a major challenge. However, milling strategies that provide high material removal rates at acceptable tooling costs demand optimized tool geometry and process parameter selection. In this paper, a description of circular milling is given, focusing on resulting engagement conditions. Regarding this, a test bench was designed to investigate the chip formation process in an analogy milling process. Furthermore, the methodology for the approach in the analogy process was developed. Results of a first test run in Inconel 718 verify the presented approach.
