“…Furthermore, the proposed mathematical model has been verified to honing screw rotors with constant lead and variable lead. Bizzarri and Bartoň [8] proposed a method for machining screw rotors with double-flank milling on the five-axis machine tool, and verified the feasibility of this method on several existing screw rotors. While these studies have provided valuable information and useful reference on forming tool design methods, they have not addressed the influence of forming tool mounting parameters on the screw rotor profile errors.…”

Characterized by a complex contour profile involving arc, cycloid and involute, etc., the screw rotor is usually manufactured by a forming tool. The finished surface quality and efficiency of the screw rotor are determined by the cutting performance of the forming tool. However, the machining performance of the forming tool is closely related to the structure shape of cutting edge, which is then determined by the installation parameters of the forming tool. Therefore, to make the cutting performance of forming tool controllable, it is essential investigate the relationship between the cutting performance of the forming tool and its installation parameters at the design stage. In this paper, a novel installation parameter optimization design method of forming tool for screw rotor is presented. A parametric optimization program is designed to finalize the range of installation parameters satisfying the spatial meshing relation and machining equipment parameters. The profile characteristics of forming tool under different center distances and mounting angles have been investigated. For validation, several screw rotors were ground in experiments and the resulted profile errors were analyzed. The results show that the cost of precision grinding of screw rotor can be significantly reduced, without compromise of machining quality. As such, the proposed design method could serve as a promising platform to faciliate screw rotor manufacture.

“…Our work aims at the final stage of the manufacturing process, called flank milling where the milling tool moves tangentially along the to-be-manufactured surface, and is therefore required to be in a tangential configuration not only at a single point, but along a whole 3D curve. It has been shown recently that screw rotors can be well approximated by helical motions of a custom-shaped tool such that the tool touches simultaneously both flanks of the rotor, resulting in double-flank milling [8]. However, such an approach requires a special, custom-shaped, tool that has to be designed, and manufactured, for each particular rotor individually.…”

“…One needs to navigate the tool to avoid collisions, yet to meet fine manufacturing tolerances. Recently custom-shaped tools have been shown to offer higher approximation quality than classical (conical or cylindrical) tools [9][10][11]. Our research belongs to this category and we look not only for the milling paths, but also for the optimal shape of the tool.…”
