[0002] In the water cutting process, due to energy attenuation, the water jet will cause the cutting angle during the cutting process, which greatly affects the cutting accuracy. Inclination method, and in order to be able to process 3D surfaces, at least five-axis cutting equipment is required. At present, the commonly used five-axis cutting equipment XYZ three-axis processing platform plus two rotation attitude axes, the two rotation attitude axes can be called five-axis head , there are two kinds of common five-axis heads, one kind of five-axis head in which the intersection of the two rotation axes does not coincide with the water jet injection point, and a kind of five-axis head in which the intersection of the two rotation axes and the water jet injection point does not coincide coincide

In the former five-axis head processing, the position of the injection point of the water jet changes when the two axes rotate, and the synchronous movement of the XYZ axes is required to compensate the cutting point; in the latter five-axis head processing, when the two axes rotate, the water jet The jet injection point will cause a certain deviation due to the accuracy of parts, assembly, thermal deformation, and workpiece inequality. This deviation has become an important factor affecting cutting accuracy. Therefore, it is difficult for many waterjet cutting equipment to complete high-precision processing at present.
