Two dimensional graphics simulation method of end mill grinding process

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.
