Embodiment Construction
[0030] To make the objectives, technical solutions and advantages of the present invention will become more apparent hereinafter in conjunction with the accompanying drawings workpiece model as an example, the present invention is described in further detail.
[0031] like figure 1 , The present invention discloses a method for automatically dividing a machining area of the workpiece, comprising the steps of:
[0032] S1: discrete regions of the workpiece. figure 2 5G shows one kind of part of an antenna module, a laser etching process requires the use of processing circuits in a specified area. Algorithm processing part model a discrete three-dimensional region meshing software (e.g., software Siemens UG) or to establish a data collection processing triangle area T. like image 3 Illustrated, shaded area required for processing on the model, using the software on the model UG discrete processing region, processing acquired data area triangles.
[0033] S2: calculating a first re...

A method for automatically dividing a workpiece processing area for a three-axis laser marking process, comprising the following steps: S1. Discrete the processing area, and establish a triangular sheet data set T of the processing area; S2. Calculate the first reference main direction, and calculate the The average normal of all triangles in the processing area data set T is used as the reference main direction for the first processing; S3, the calculation of the first sub-processing area, according to the first processing reference main direction obtained in step S2, S4, repeat steps S2 and step S3, calculate the second machining direction and the subsequent machining direction until the number of triangles remaining in the triangular piece data set T of the processing area is zero, that is, the machining sub-area division during three-axis machining of the part is completed . The present invention is a processing area calculation method with wide applicability, which improves the speed and accuracy of the model processing area division; through the automatic division method, the division result of the processing area can be calculated quickly and accurately, which is very useful for different types of parts Good applicability.
Description
Technical field [0001] The present invention relates to a process of manufacturing the triaxial laser standard, and more particularly, to a method of automatic division processing region marking process for triaxial laser. Background technique [0002] Triaxial process widely used in machining, laser machining, measurement, which is characterized by the use of three-axis drive mechanism execution means (machining tools, such as milling, laser galvanometer, measured top), the inner space surface to achieve high-speed Parts high finishing process. Process characteristics triaxial moving mechanism is not rotational degrees of freedom, making it impossible to achieve any processed to a machining position, but at lower costs can be high speed high precision. [0003] In recent years, laser processing because of its unique characteristics, has become a hot research direction of machining. Compared with the conventional processing methods, the laser processing has several advantages: Fi...
