Method for applying CAD (computer-aided design) drawing to precision finger-type milling cutter for involute gears

Abstract

The invention discloses a method for applying CAD (computer-aided design) drawing to a precision finger-type milling cutter for involute gears. The method is characterized in that a cutter CAD system is constructed on the basis of a UG (Unigraphics) platform, various three-dimensional parameters of the finger-type milling cutter are inputted to generate a three-dimensional entity model, a three-dimensional parameterization technology is analyzed and summarized, and purposes of automatically generating a three-dimensional model of the precision finger-type milling cutter for the involute gears and two-dimensional CAD graphs and automatically labeling dimensions are achieved by the aid of the parameterization technology and a UG secondary development technology. The method has the advantages that problems that computation is troublesome and errors are easy to make in a precision finger-type milling cutter designing procedure are solved, and purposes of improving the design precision, shortening a product design cycle, reducing the design cost and avoiding design errors are achieved. The method is widely applied to CAD parameterization design for finger-type milling cutters for machining gears according to a form copying principle and a non-instantaneous-pole envelope principle.

Description

technical field [0001] The invention belongs to the technical field of CAD parametric design of gear cutters, and mainly relates to an application method for CAD drawing of involute gear precision finger milling cutters. It is widely used in the CAD parametric design of finger milling cutters used for machining gears according to the principle of profiling method and the principle of non-instant center enveloping method. Background technique [0002] The traditional design of gear cutters requires a large amount of theoretical knowledge and a lot of related manuals to be consulted. The design process usually uses manual calculations, which are cumbersome, heavy workload and error-prone. [0003] At present, domestic gear cutting tools are mostly high-speed steel cutting tools, which are generally processed by ordinary machine tools, and there are many problems in processing efficiency and processing accuracy. The research and development trend of foreign gear cutting tools ...
