Problems solved by technology

Even so, the S-shaped curve planning method still has the following defects: the calculation method is complex, usually iterative method, dichotomy method and the relationship between kinematic speed, acceleration and time are used for calculation. A large number of calculations reduces the response speed of motion control and limits The application of advanced and complex interpolation trajectories is realized, which is difficult to apply to complex and high-precision curved surface multi-axis synchronous interpolation processing of higher-end machine tools
