Abstract
Currently, when machining gears, the main problem arises - the resistance of a standard worm mill. In the current conditions of sanctions, import substitution and the launch of the State program for the development of its own metal cutting tool designs by tool companies, the creation of prefabricated structures can be considered a promising and effective solution, since this has been repeatedly confirmed by leading Russian researchers [1-8].
Highlights
There are many methods of processing gears, but let us dwell on the method of rolling using worm cutters
You must start with the placement of replaceable cutting hard-alloy elements in the initial outline of the tool rack
In accordance with GOST 13755-81, we carry out mathematical calculation and construction of the initial outline of the tool rack in the Kompas-3D software (Fig. 1)
Summary
There are many methods of processing gears, but let us dwell on the method of rolling using worm cutters. Tool companies in the Russian Federation today do not offer designs of prefabricated worm cutters for processing large-module gears capable of providing the required performance, high productivity and economic efficiency in toothfreasing.
