Problems solved by technology
[0004] Most of the existing FTS are mainly limited to single-degree-of-freedom FTS and two-degree-of-freedom FTS, such as FTS that reciprocates along the Z axis, FTS that reciprocates around the Y axis, and reciprocating motions along the X and Z axes. FTS, and most of the existing FTS strokes are micron-level, which makes the existing FTS unable to realize the large-stroke synchronous reciprocating motion of the X-axis, Y-axis and Z-axis, and cannot generate free-form surfaces with large curvature radius changes. processing, so it is difficult to realize the tool path planning method aiming at the autonomous control of surface topography
