“…The model allowed the predicting cutting force with a 96% confident interval. By the least squares regression and the elimination process, the quadratic model of actual axial cutting force could be presented in equation (1). While other factors were kept constant, the single and interaction influences on F a were presented in Figure 2(a).…”

“…For a large screw, the whirlwind milling (WM) has been widely applied. 1 Due to the specific characteristic, the geometric error, especially for the accumulated pitch error, was inevitably and even unfavorable under some unreasonable process parameters. The cutting force and temperature have direct effect on the accumulated pitch error of screw.…”

For cutting a large screw, the cutting force and temperature have direct impact on machined surface quality, such as accumulated pitch error in geometric error. Excited by cutting force, the axial deflections directly affecting accumulated pitch error were studied based on the beam theory. By experiments, the axial cutting force was predicted with a 96% confident interval, and the tool number and cutting depth were found to be significant terms. Tested under increasing cutting speeds, the temperature rise of workpiece and accumulated pitch error both decreased obviously. Thus the higher cutting speed could improve the cutting precision of a full-length large screw.

“…The worm profile's effect on the tool head's tilting angle is analyzed. To use the same machining method, Andrianto et al [5] proposed a general method to manufacture the enveloping worms using a whirl machining process with the tool profile formed by a straightlined blade. Skoczylas and Pawlus [6] proposed a method for manufacturing the concave profile of worm thread by the tapered end mill in a CNC machine.…”

The cylindrical worm is usually manufactured by generating methods, such as hobbing and whirling; however, the aforementioned methods are restricted to manufactured time and control machining profile with stock. Therefore, this paper introduces a novel machining process designed for ZC concave worms, simultaneously enhancing machining efficiency and profile control ability. Accordingly, a skiving cutter with multiple inserts on an internal helical gear tooth is proposed. A curve-fitting model of the generating rack is first illustrated to generate the ZC worm flanks when considering grinding stock conveniently. The position of the cutting edge is then analyzed via the geometry of an internal barrel worm to ensure non-interference during the cutting process. In addition, the insert body is generated based on the helicoid motion of the cutting edge. Subsequently, it also presents a machining process to grind the insert body. Furthermore, the skiving process employing multiple inserts on a multi-axis CNC machine is presented. Finally, the meshing and boundary points of the cutting trajectory are concurrently defined during the skiving process. The numerical and virtual experimental results demonstrate the high precision and absence of overcutting in skived worm profiles.

“…Mathematical modeling methods of tools have been studied in the extant literature, such as milling tool [23][24][25][26], turning tool [27], skiving tool [28], worm-shaped tool [29], barrel-shaped tool [30], form-cutting tool [31] and others [32][33][34][35][36]. A mathematical modeling method of the whirl-machining tool has recently been utilized to simulate double enveloping worms manufacturing [37]. This paper proposes the technique of manufacturing globoidal cams with a whirl-machining tool.…”

The whirl-machining process is a precise, efficient, and promising machine process for manufacturing workpieces over the milling process. At the same time, the roller-gear cam has advantages over the other camfollower system. However, the whirl-machining process has not been applied to manufacture the roller-gear cam. Therefore, this paper proposes a novel method for roller-gear cam manufacturing using a whirl-machining process. Mathematical modeling is described for generating the roller-gear cam, roller, and whirl-milling tool surface. A novel CNC machine and its coordinate system are proposed. Cutting simulations for obtaining the surface topologies and normal deviations are conducted. Globoidal cam with different cylindrical rollers, globoidal cam with a conical roller, and cylindrical cam with a conical roller are taken as case studies, and results are discussed. A virtual cutting simulation was conducted using VERICUT. Some machining examples are shown to verify the benefits of the proposed method in roller-gear cam manufacturing.
