    摘要： The present disclosure relates to servo control technology, which provides a method, device, and terminal device for servo movement smoothing. The method includes: obtaining a starting position and a control command for a rotation of an output shaft the servo; determining an ending position and a rotation time for the rotation of the output shaft in accordance with the control command; constructing a movement curve of the output shaft based on the starting position, the ending position, and the rotation time; and controlling the output shaft to rotate from the starting position to the ending position in accordance with the movement curve. The above-mentioned method smooths the movement of the servo by constructing a simple linear function, which greatly reduces the calculation amount in comparison with the technical solution using the cubic Bessel formula, and is capable of reducing the requirements for the hardware performance of servos.

    摘要： A numerical controller having a function of optimizing a corner path at a corner of tangent continuity includes a path conversion unit for obtaining a curved correction path passing through three points corresponding to a start point and an end point of a third block, and a shift point obtained by shifting an intermediate point of a command path based on the third block in an inward direction of a corner path within a limit of a preset allowable error amount when the corner path is formed by a series of blocks and a tangential direction of the corner path is continuous, and generating a path obtained by replacing the command path of the third block included in the corner path by the correction path, the third block commanding curvilinear movement at a larger curvature than a first curvature and a second curvature being interposed between the first block commanding rectilinear movement or curvilinear movement at the first curvature corresponding to a small curvature and the second block commanding rectilinear movement or curvilinear movement at the second curvature corresponding to a small curvature in the series of blocks.

    摘要： Optimized positioning paths for multi-axis CNC machining can be generated based on the machine tool kinematics, machine axes travel limits, machine axis velocity and acceleration limits, and machine positioning methodologies. Machine axes travel limits and machine positioning methodologies are incorporated in order to ensure that the developed positioning paths do not violate machine axes travel limitations. Multi-axis positioning paths are developed to avoid collisions with dynamically changing in-process stock and other surroundings, including fixtures and both moving and non-moving components of the machine. Positioning tool path customizations give the user the flexibility to apply safety based constraints to the automatically generated tool paths. The disclosed automatic positioning path planning and optimization methods are used to develop a process for part manufacturing using CNC machining in order to reduce the manufacturing cycle time.
