Problems solved by technology
The traditional glass grinding process is realized by workers operating the grinding machine. This method requires relatively high skills and experience for workers, and the production efficiency is low. The consistency of product patterns is poor, and complex patterns are not easy to achieve.
With the development of society and the improvement of consumer demand, traditional production methods are gradually unable to meet the needs of production, and a new production method is urgently needed. The emergence of five-axis CNC machine tools just fills this gap, but how to edit five The glass grinding path of the axis CNC machine tool has become a big problem

The invention relates to the technical field of computer aided design and manufacturing, in particular to a method for generating a glass polishing machining path of a five-axis numerical control machine. The method comprises the following steps of: A, constructing a geometric curved surface representing the shape of a product; B, designing a polishing shape curve on a plane and defining the section shape of a polishing grinding wheel; C, defining a cone tool according to the section shape of the polishing grinding wheel; D, generating a five-axis path of machining of a tool nose of the cone tool; E, simulating and previewing a machining effect and regulating the five-axis machining path to ensure the five-axis machining path to meet the design requirements of the product; F, mapping the machining path of the cone tool on the plane to the curved surface constructed in the step A; and G, converting the machining path of the tool nose of the cone tool into a polishing machining path of the grinding wheel. According to the invention, glass polishing is carried out by using the five-axis numerical control machine, patterns of the product have good consistency, and complex patterns canbe machined. Meanwhile, the production efficiency is improved, the production cost is reduced and the development period of a novel pattern is shortened.
Description
technical field [0001] The invention relates to the technical field of computer-aided design and manufacturing, in particular to a method for generating glass grinding paths of a five-axis numerically controlled machine tool. Background technique [0002] Glass grinding is gradually applied in the processing of high-end wine bottles and other products. Compared with the pattern of casting, the edges and corners of the grinding wheel are clear and the shape is free, which can improve the grade of the product. The traditional glass grinding process is realized by workers operating the grinding machine. This method has relatively high requirements for workers' skills and experience, low production efficiency, poor consistency of product patterns, and complex patterns are not easy to achieve. With the development of society and the improvement of consumer demand, traditional production methods are gradually unable to meet the needs of production, and a new production method is ...
