Two dimensional graphics simulation method of end mill grinding process

Abstract

The invention discloses a two-dimensional graphics simulation method of an end mill grinding process, belonging to the technical field of two-dimensional simulation. The two-dimensional graphics simulation method solves the problem that it is difficult for the cutter grinding software in the prior art to find a normal section and an end section in the cutter grinding three-dimensional model, and further difficult to measure the cutter. The two-dimensional graphics simulation method comprises that firstly cutter position track data of a grinding wheel is read and a section cutting plane of the end milling is specified, relative position between the grinding wheel and the section cutting plane is analyzed and whether the grinding wheel corresponding to a cutter site intersects the section cutting plane is judged; if so, an intersecting contour curve of each cutter site corresponding to the grinding wheel and the specified section cutting plane is solved in order and the section cutting plane of all the grinding wheels is obtained; the section cutter planes of all the grinding wheel are superimposed to obtain a two-dimensional truncate section of a cutter slot; the two-dimensional section of the cutter slot is measured to determine whether the two-dimensional truncate section of the simulated cutter slot satisfies the machining precision; if not, a grinding process is modified. The invention is used to simulate the two-dimensional truncate of the cutter slot.

Description

technical field [0001] The invention discloses a two-dimensional graphics simulation method for the grinding process of an end mill, which is used for simulating the two-dimensional sectional shape of a tool flute, and belongs to the technical field of two-dimensional simulation. Background technique [0002] The main purpose of grinding simulation is to test the feasibility of grinding process and its grinding precision. However, the characteristic surfaces of end mills are mostly composed of complex curves such as helical surfaces and arc surfaces. It is difficult to measure the 3D tool model based on 3D machining simulation, and the 3D simulation is restricted by the accuracy of the entity Boolean algorithm and the efficiency of graphic display. The tool model obtained by 3D simulation is not accurate, and its accuracy detection has no practical significance. [0003] At present, the functions of most tool grinding software at home and abroad mainly focus on the processi...

Problems solved by technology

[0007] The present invention provides a two-dimensional graphics simulation method for the grinding process of end mills in view of the above shortcomings, which solves the problem that the curve fitting model obtained by three-dimensional simulation in the prior art is limited by the graphics fitting accuracy. There is a large error in the data; it is difficult to obtain the normal profile and end profile in the simulation model for spiral end milling tools, so parameters such as normal rake angle, normal relief angle, end rake angle, and end face relief angle of end milling tools cannot be measured , so it is difficult to accurately measure the end milling tool
