Problems solved by technology

Therefore, in the processing of image files, CAD / CAM software is an evasive attitude. In theory, image files cannot be used at all.
At least it cannot be used in the production of parts with precision requirements
[0004] Now everyone wants to know how to use some algorithms to recognize the picture into a format acceptable to CAD / CAM. This way of converting and processing is very painful.

Embodiment Construction

[0039] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative work, any modifications, equivalent replacements, improvements, etc., shall be included in the protection scope of the present invention Inside.

[0040] The conversion method of dot matrix diagram of the present invention and CAD / CAM vector diagram, the step of this conversion method is:

[0041] S1, define the straight line standard, correspondingly generate the straight line chart file under the vector diagram from the straight line chart file in the standard bitmap, form a one-to-one straight line picture pair, this line picture pair is made up of a straight line...

Abstract

The invention discloses a method for conversion between a lattice graph and a CAD / CAM vector graph. The method comprises: S1, a straight line standard is defined and a straight line graph pair is formed; S2, an arc line standard is defined and an arc line graph pair is formed; S3, a simple graph file in a standard lattice graph is decomposed by means of adjustment, a simple graph vector file is generated, and a simple graph pair is formed; S4, an original graph pair is stored into a database to form an original graph pair database; S5, a complex pixel graph file in the standard lattice graph is decomposed by means of adjustment to form original graph file combination and a complex pixel graph vector file of the complex pixel picture is generated; and a complex pixel graph pair is generatedand is stored into the database to form a complex pixel graph pair database; and S6, in a CAD / CAM environment, a CAD / CAM program reads the complex pixel graph vector file of the complex pixel graph pair in the complex pixel graph pair database and generates a complex pixel graph file corresponding to the complex pixel graph vector file.

Description

technical field [0001] The invention relates to the technical field of graphics conversion, in particular to a method for converting bitmaps and CAD / CAM vector graphics. Background technique [0002] CNC equipment can be operated unmanned, but a qualified processing program needs to be written and debugged beforehand. This processing program can be automatically generated by manually calculating point coordinates or by CAM software. For a CAM software, it also needs a mathematical model. If the model is simple, it can be built in the CAM environment, and if it is complicated, it can be built with CAD software. Therefore, we often put CAD / CAM together, and CAD builds the model. CAM uses this model to generate machining programs. Then this mathematical model is the key technical node. The next step of processing is possible only if the existing model is required. There are many CAD software on the market today, which are used to build such models. For example, Solidworks,...
