TECHNOLOGICAL PROCESS OF MODELING

COUPLED GEAR ENGAGEMENTS IN WEAPONS AND MILITARY EQUIPMENT

Abstract

This article examines the technological process of modeling a cutting tool by circular projection and the profiled initial tool surface of the cutting edge. In the AutoCAD automated design system, a technological process is proposed during the modeling of disk and worm cutters for processing conjugate surfaces of an arbitrary profile for processing parts and mechanisms during the manufacture of samples (complexes) of weapons and military equipment and their repair. One of the most common tasks that arise during the technological preparation of production is the design of a cutting and measuring tool. The design of cutting tools in the form of worm and disk cutters occupies a special place, as it is associated with more complex calculations. Worm milling cutters are used for roughing and finishing of cylindrical parts of external engagement with straight, helical and chevron teeth. Such cutters can work with axial, radial, diagonal and tangential feed.

Designing a cutting tool for processing helical kinematic pairs of an arbitrary profile is a very time-consuming process. The technical solution of computer modeling of a cutting tool for processing complex conjugate toothed surfaces increases the productivity of calculation and design work and accuracy during the manufacture of gears as parts of the main nodes and mechanisms in samples of missile and artillery weapons and military equipment.

Keywords: circular projection, technical solution, modeling, cutting tool, conjugate surfaces of rotation, helical surfaces, curved surface, dynamic parameters, parameterization, technical solutions, theoretical methods
