Abstract

The invention discloses a robotic cutting method for profile steel, which is based on the robot offline programming. The method comprises the following steps of: reading a CAD graphics file to obtain geometrical characteristics of profile steel cutting; generating a cutting unit by a path planning and a cutting parameter design of the geometrical characteristics; determining an action parameter and a cutting parameter of a cutting gun and generating a trepanning file by a placement planning of the cutting unit on profile steel having a specific length; converting the trepanning file to be a robot executable program in accordance with the robot program format, and achieving the cutting of the profile steel. Based on the robot offline programming technology, by utilizing the designed information of CAD graphics directly, the robotic cutting precision and efficiency can be increased; the method is suitable for cutting requirements of groove-type profile steels, such as V-type, Y-type andthe like and varied-groove-type profile steel; the problem of the poor cutting quality at the edge of an angle steel or other steels is solved; the method has the characteristics of generality, flexibility, high efficiency and high precision.

Description

technical field [0001] The invention relates to the field of shipbuilding, in particular to a robot cutting method for section steel. Background technique [0002] The shipbuilding industry has a huge amount of material cutting and high quality requirements. Before welding, marine section steel needs to be cut into various shapes of ends, intermediate holes and welding grooves. The traditional manual scribe cutting or special machine scribe cutting has low cutting efficiency and poor quality, which seriously restricts the development of the shipbuilding industry. This greatly increases the requirements for automated production of marine section steel cutting, and the use of robotic flexible cutting technology can well meet the needs of cutting production. However, if the teaching method is used, the required man-hours are long, the cutting efficiency is low, and the cutting accuracy is greatly reduced, which affects the overall performance of the system. The use of CAD / CAM / ...
