“…Equation (28) relates three parameters, so it differs significantly from the envelope condition for the case of shaping the cylindrical helical surface, where only two parameters occur (there is no relative tool and worm motion parameter in the envelope condition). The cylindrical helical motion can be written with the helical motion of the characteristic (as well as its arbitrary section) [13,14].…”

In industrial practice, cylindrical worm gears are most often used due to their feasibility. In the literature, much attention has been paid to determining the helical surface of worms of such transmissions. Globoidal worm gearboxes are much less frequently used due to technological difficulties. Come on, the globoidal worm ensures simultaneous cooperation of a larger number of teeth and the location of the teeth contact line is more favorable. Therefore, the following is an analytical method for the description of a globoid surface by turning and by a finger milling method.

“…Despite so many achievements in manufacturing technique, this is a difficult issue and requires specialized equipment. Worms and gears with any axial profile can also be produced using simple geometrically universal cutting tools by Step-by-Step method on universal CNC-controlled machine tools [9,17,18,19,20,21]. With this method, the tool surface and the machined one are not coupled (mutually enveloped), therefore the machining accuracy is determined by the number of tool passes and also the density of the tool movement path during cutting.This machining technology is used, among others, for shaping injection molds, turbine blades, and has also proven itself in the production of non-circular cog belt pulleys [10].…”

Despite the fact that worm gears have been known for millennia, they are still used and they are constantly improved and developed. The goal is to obtain a gear that is not wearing out under the assumed operating conditions. That is why such an important issue is the ability to make worms with a defined profile as well as with a certain accuracy. This directly affects the durability of the worm gear. Comparing worm gears with concave-convex surfaces with conventional cooperation surfaces worm gears, they are characterized by: more favorable change in the distribution of Hertz pressure, change in the course of the contact line between the cooperating surfaces and an increase in the thickness of the worm wheel tooth at the base. In this way, improved power transmission and lubrication properties can be expected, what consequently results in less energy loss and less wear. The article presents the method of forming helical surfaces with a circular concave axial profile by the point method and the developed code generation program for controlling a universal multi-axis CNC machine tool.

“…Nowadays, due to the increasing use of universal multi-axis CNC machines, there is a tendency to transfer gear production from special machine tools to CNC machine tools [1][2][3][4][5]. Similarly, for gear measurement, in place of special measuring machines, a universal toolmakers microscope can be used.…”

Comparsion of measuring methods for the involute profile of the spur gear tooth is described in this paper. The gear profile measurement results from the universal toolmakers microscope are compared with the results of use of Zeiss coordinate measuring machine with Gear Pro software and with the results of the theoretical calculation of the reference profile. The proposed measurements methods can be successfully used in quality management of unit production of gear drives.
