Abstract
Description
technical field
[0001] The invention relates to a numerical control cutting machine tool, in particular to a double-gantry horizontal mixed-connection principle turning-milling compound numerical control machine tool which uses both serial and parallel connections. Background technique
[0002] The traditional machine tool is based on the principle of complete serial connection, which has the advantages of large working space and simple motion algorithm of the machine tool; the disadvantage is that the motion errors of each axis accumulate, the cantilever structure has weak rigidity, the motion mass is large, and the speed cannot be too high. In recent years, the United States has first introduced a six-axis fully parallel machine tool, also known as a virtual axis machine tool or a hexapod parallel machine tool. The space is small and the motion algorithm is complex. At present, in addition to realizing the advantage of fast speed, the fully parallel machine tools develope...
