“…The generation process kinematics of the helical surface of the threaded gap assumes the following movements, figure 4, [7]: I is the revolving movement of the blank around its own axis, ϕ is the rotation angle; II -translation movement of the blank along the rotation axis, making a helical movement with the same pitch with the surface to be generated.…”

In this paper, it is analyzed, in a comparative way, two methods for profiling disc tools (mills or grinding wheels) for generation of specific threads used in the construction of the prosthetic screw for dental implants. It is proposed an analytical method, based on the fundamental theorem of the surfaces enveloping versus a graphical method, developed in CATIA. They are presented numerical examples for the both methods.

“…Actually, disk tool profiling is often supported by expensive dedicated software based on advanced methods, which are still secret and only suitable for large companies. _____________ One nowadays advanced trend is the CAD approach, such as using the "Projection" command on CATIA to project the disc-tool axis onto the machined surface to get characteristic curve [8], machining simulation and identification of contact lines by Boolean operation [9][10], and the method of "relative generating trajectories" [11][12][13] but these works were written not in detail and almost ignored the problem of undercutting as well as the impact of disc tool position on the accuracy of the air compressor screw pair.…”

One of the best practical methods to machine the air compressor screw pairs is milling or grinding by disc tools. The mathematics involved in disc tool profiling is quite complex and requires representing the machined surface by mathematical equations without any singular points and undercutting. From a technical perspective, this article proposes the disc tool profiling integrated solution for machining complex profile screws from their reverse engineering data, which contains crucial issues such as machining deviation evaluation due to undercutting, appropriate tool position setting. The disc tool surface designed by the proposed method is highly accurate, leading the RMS error of the machined surface is less than 0.0201 mm. A difference of the angle, formed by the disc tool axis and the workpiece axis, less than 0.16°, is acceptable in air compressor technology, which leads to a machined surface RMS deviation of less than 0.0186 mm.

This paper presents a newly developed analytical model with application in profiling the hob mill for generating a pump rotor having four circular lobes with rectilinear directrix. The analytical model of rotor surface is deducted at first. The generating rack-tool is secondly determined and then, the peripheral surface of the hob mill results as envelop of surfaces family generated by the successive positions of generating rack-tool. The profiling solution lies on the fundamental theorems concerning the reciprocal enwrapped surfaces. A calculus algorithm and a numerical model developed in MatLab are proposed. The characteristic curve of hob mill tooth surface is found out in the case of a given rotor profile. Index Terms-Quadrilobed rotor, analytical model, hob mill profiling, intermediary surface method.
