Problems solved by technology

It is precisely because of the change of the angle of the cladding head that the coordinate system of the robot system is actually constantly changing during the working process, and the position information of each pass is difficult to determine, making it almost impossible to program the trajectory manually, which greatly limits the robot. Development of an automated cladding process and control of cracks in additively manufactured alloys

Abstract

The invention relates to a path development method for curved surface multi-pass linear cladding. The method is characterized in that program development is performed by using WorkVisual software of a KUKA robot, the length and the width of a substrate are respectively 50 mm, the heights of the lowest point and the highest point of the curved surface are respectively 137 mm and 150 mm, and the substrate is made of low-carbon steel, and is mainly used as a mold insert of a certain type in production. As only the transverse and longitudinal displacement values of each pass need to be obtained, and referring to the Fig. 3, only the two-dimensional contour of the curved surface needs to be reconstructed through AutoCAD software, the path development method for curved surface multi-pass linear cladding provided by the invention can be used for performing manual programming rapidly through WorkVisual software of the KUKA robot on the premise that there is no special additive manufacturing slice and trajectory planning software, so as to obtain a complex multi-path linear cladding trajectory program.

Description

【Technical field】 [0001] The invention relates to the technical field related to laser manufacturing additive materials, in particular to a path development method for multi-line cladding on curved surfaces. 【Background technique】 [0002] Metal components are the main structural parts in industrial production, and curved surfaces are one of the most common component structures. However, for curved surfaces with large load-bearing and severe wear during work, they are prone to failure during service. Therefore, surface repair or surface strengthening on the surface of curved components is a necessary way to improve component life. [0003] Due to the consideration of the processing accuracy and low production efficiency of manual cladding, digital-based automated additive technology has increasingly replaced traditional manual welding repairs. Among them, due to the high flexibility of work, robot-based automated additive repair technologies, such as laser cladding, arc ad...
