Description

technical field [0001] The invention belongs to the field of precision device processing, and in particular relates to a five-axis ultrasonic vibration numerical control machine tool for composite laser processing. Background technique [0002] Traditional mechanical numerical control machining is already a relatively mature process. The control system issues instructions to make the tool perform cutting movements that meet the requirements, and express the technical requirements such as the size and shape of the workpiece in the form of numbers and letters, as well as the processing technology requirements for processing. The basic composition of CNC machine tools includes processing program carrier, CNC device, servo drive device, machine tool body and other auxiliary devices. The machining accuracy of CNC machine tools can generally reach 0.05-0.1mm. In more precise processing technology, the machining accuracy of CNC metal cutting machine tools can reach a smaller level,...

However, it is much more difficult for the laser to precisely control the size and shape of blind holes and shapes, especially the softening and performance changes of materials at high temperatures.

[0008] 3. The laser radius of laser processing has a great influence on the finished product quality of the processed workpiece. The larger the laser radius, the harder it is to concentrate the distribution of energy density, which will cause the energy concentration part of the central part to quickly heat the processing part during processing. Even gasification, while most of the lower energy outer ring can only liquefy the workpiece, or even heat the workpiece surface to a certain extent

[0009] 4. There may be residual stress on the surface of the machined workpiece
