Embodiment Construction

[0058] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Several embodiments of the invention are shown in the drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided so that the disclosure of the present invention will be thorough and complete.

[0059] It should be noted that when an element is referred to as being “fixed on” another element, it may be directly on the other element or there may be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. The terms "vertical," "horizontal," "left," "right," and similar expressions are used herein for purposes of illustration only.

Abstract

The invention provides a laser path planning method and system, a computer and a readable storage medium, and the method comprises the steps: carrying out the maximum division of a to-be-processed surface of a target component according to a preset shape, and then carrying out the division of a remaining surface according to the preset shape, so as to divide the remaining surface into a plurality of processing regions; the first laser point and the second laser point are arranged at one set of opposite corners of the machining area correspondingly, and the first laser point and the second laser point are subjected to relative movement reciprocating scanning according to the preset scanning speed; and respectively moving the first laser point and the second laser point to the other group of opposite angles, and carrying out relative movement reciprocating scanning on the first laser point and the second laser point again so as to complete scanning of a second opposite angle region corresponding to the current opposite angle. According to the method, double lasers are adopted for scanning, and a transverse and longitudinal combined scanning method is adopted, so that the temperature gradient can be effectively reduced, and the effect of greatly reducing the residual stress is achieved.

Description

technical field [0001] The invention relates to the technical field of laser additive manufacturing, in particular to a laser path planning method, system, computer and readable storage medium. Background technique [0002] Additive manufacturing (AM) technology was proposed in the 1970s. After half a century of research and development, it is already a relatively mature technology that can be well applied in practice. Additive manufacturing technology has the characteristics of rapid and free forming in the manufacture of complex-shaped parts. It can complete the processing of parts with complex structures that cannot be completed by traditional manufacturing methods, simplify the processing process, improve production efficiency, and shorten the production cycle. [0003] Compared with the traditional "subtractive" or "removal" technology, "additive" is the main distinguishing point. Additive manufacturing technology can overcome the large waste of raw materials caused by ...
