System and method for designing and processing characters for tire mold in three-dimensional CAD/CAM environment

Abstract

The invention relates to a system and a method for designing and processing characters for a tire mold in a three-dimensional CAD / CAM environment. The system mainly comprises a character design module, an NC data generation module and an NC device, wherein the character design module is connected with the NC data generation module through a three-dimensional CAD / CAM system; and the NC data generation module is connected with the NC device; the character design module is used for designing and editing characters in the three-dimensional CAD / CAM environment and extracting character outlines for display; the NC data generation module is used for generating a cutting track according to the character outlines and further generating an NC program according to the condition of a machine tool; the NC device is used for controlling processing actions of the machine tool to process the characters according to the NC program; and the three-dimensional CAD / CAM system is an operating platform of a character designing and processing system for the tire mold, and connects the character design module with the NC data generation module through CAD / CAM-identified line elements.

Description

technical field [0001] The invention relates to a system and method for designing and processing characters for tire molds in a three-dimensional CAD / CAM environment. Background technique [0002] At present, in the design and production of tire molds, a lot of work involves the design and processing of characters, and the existing 3D CAD / CAM system cannot meet the various design and processing needs of companies on products. [0003] At present, the CAD software used by enterprises can also realize the design and processing of text, but the operation process is cumbersome, the designed text is not good, and the machinability is low. Now the common computer-aided design of text is completed through the following operations. First, design the text in 2D CAD, and then import it into the 3D model, select the outline of the text one by one, judge the processing sequence, and generate the processing path. The shortcoming of this operation process is: 1) text can not be revised a...

AI Technical Summary

Problems solved by technology

The disadvantages of this operation process are: 1) After the text is imported into the 3D CAD, it cannot be modified. If there is any modification, it must be modified in the 2D CAD, and then re-imported into the 3D CAD.

4) It cannot meet the various text arrangement methods of tire mold enterprises

5) The accuracy of text processing on the side of the curved tire cannot be guaranteed
