Abstract

The invention provides a cutting process offline coordination method of multi-beam type water jet cutting system. The method comprises the following steps: dividing a processing area of the multi-beam water cutting system; inputting a CAD (computer-aided design) file of a large workpiece to be cut, and decomposing and allocating the cutting contour accordingly to form the CAD sub-file of the cutting part of each beam system; importing each CAD sub-file into water cutting CAM (computer-aided manufacturing) software to generate an executable NC (numerical control) code file, and reading the NC code file to obtain a sequence of the cutting path of each beam system; calculating a time window executed by each path in each cutting sequence, and coordinating the time windows in an interference area so as to achieve the purpose of avoiding mutual interference between two adjacent beams; and writing the coordination result into the original NC code file, downloading the NC code file to a CNC (computer numerical controller) of each beam system, and executing the multi-beam water cutting process. According to the invention, smooth and non-interference execution of a parallel cutting processes of a water cutting system with more than three beams can be realized.

Description

technical field [0001] The invention relates to the field of numerical control water jet cutting processing, in particular to an off-line coordination method of a multi-beam water jet cutting system for large workpieces. Background technique [0002] Waterjet cutting (hereinafter referred to as water cutting) is cold processing, without thermal deformation, non-selective processing materials, fast cutting speed, and no pollution. It is obviously superior to other cutting methods, such as hard tools, electric sparks, Laser, plasma and other cutting methods. In recent years, with the rapid growth of the demand for waterjet cutting of large workpieces, such as aircraft wings and ship decks, two large-scale waterjet cutting machine solutions have emerged, namely large-scale gantry single-beam systems and multi-beam systems. The large-scale gantry-type single-beam system expands the guide rail and worktable on the basis of ordinary waterjet cutting machine tools. It uses a singl...
