Fundamentals of CAD Design of Rotary Milling Cutters for Multitooth Products

Abstract

The studies presented in the article are aimed at developing the basics of ensuring the creation of CAD systems for disk run-in milling cutters for machining multitooth products regardless of profile. The development of this tool is based on its design methodology, which is based on the theory of shaping and design of cutting tools. Based on the analysis of the methods of processing multitooth products, the prospects of processing multitooth products with round disc milling cutters are substantiated. In this work, the problem of determining the cutting edges with the perpendicular and inclined axes of the tool and product is solved. The smallest design diameter of a disk run-in mill is determined. The design of the run-in mills, which provides the manufacture of chip grooves between the teeth of the product, is considered. The development of the design of the disk run-in mills included determining the diameter, taking into account regrinding. The geometric parameters of cutters are established. Based on the developed methodology for creating a CAD system for disk rolling mills, an automated system for designing disk rolling mills has been created. The operation study of milling cutters designed using this system confirmed the high accuracy of the products and prospects of their application. It is shown that the development of CAD systems for such mills significantly reduces the design and technological preparation of the production of multitooth products by disk rolling mills.
