An interlocking side mill with retrofittable carbide blades for processing of coarse-pitch tooth wheels

Abstract

Nowadays Russian manufacturers of metal-cutting tools for machine-building industry do not offer structures of prefabricated cutting hobs with retrofittable carbide blades for processing of tooth wheels, though usage of retrofittable carbide blades allows to increase significantly working capacity and productivity of the processing. As of today creation of an assembly cutting tool for processing of tooth wheels with the retrofittable carbide blades is a big step forward for machine-building industry. A high quality tool allows warranting for a new equipment and making work of operators more productive. This paper offers a new technical solution providing increase of efficiency of processing by assembly tools with the retrofittable carbide blades made of a hard alloy. Due to usage of progressive cutting patterns division of a margin for straight-line segments and curved sections is performed. This division has a positive impact on cutting hard-alloy inserts and also reduces their wear and tear.

Implementation of a Group Cutting Scheme during Processing of Large-Module Gears with a Prefabricated Tool

“…It suggests the idea of arranging the cutting elements in the tool body tangentially. Works [17][18] proposed a combined arrangement of RHACB in the tool body. This arrangement of cutting elements in the body of the dental tool is called group.…”

Modeling of process of gear milling for definition of the intense deformed state in replaceable many-sided plates of a worm mill

“…The maximum cross-sectional area of the cut-off layer for a full-height mill is 2. Throughout article [16][17] the research for calculation of the intense deformed condition of the replaceable cutting plates with the full-height and progressive scheme of cutting was conducted. The experimental task of improvement of a final and element grid and influence of quantity of elements was carried out to grids on results of tension in WC-Co alloy with use of the program of the final and element analysis of ANSYS.…”
