摘要： A curve interpolation method capable of obtaining a curve approximating an original curve based on a sequence of command points within a tolerance set for the original curve, and performing interpolation on the obtained curve. Points Q1, . . . , Q2n are interpolated between respective two adjacent command points (P0, P1), (P1, P2), . . . , (Pnnull1, Pn) as shape-defining points. The shape-defining points are positioned within a tolerance width 2w set to the original curve. One shape-defining point and shape-defining points surrounding the one shape-defining point are successively selected and an approximate curve for the selected shape-defining points is successively created. The one shape-defining point is moved towards the approximate curve to determine a modified shape-defining point for the one shape-defining point. A smooth curve passing a sequence of the modified shape-defining points is created and interpolation for machining is performed on the created curve. Since the shape-defining points are positioned closer to an original target curve within a tolerance width set to the original curve than the command points, the created smooth curve passing the sequence of modified shape-defining points is well approximating the original target curve within the tolerance width.

摘要： A motion controller includes an input for receiving data corresponding to moves in a cycle of a multi-axis machine. The controller controls electric motors of the machine in accordance with positions set forth in a path planning table. The path planning table is generated from the data by applying a curve defining equation and integrating an alpha variable therein. The alpha variable corresponds to a velocity to acceleration ratio and is adjustable to allow the calculation of a new path planning table having a velocity and acceleration profile shifted from an initial velocity and acceleration profile to allow for optimization of motor performance. A method of path planning having user tunable parameters is also provided.

摘要： An iterative spline function controlled positioning mechanism such as a machine tool. A movable element of the machine tool is driven about a plurality of axes under computer control along a path formed by a plurality of sections. Each of the path sections is represented in parametric form by spline functions. The element is driven through a plurality of intermediate positions approximating positions on the path sections. An iterative algorithm implemented by the computer permits efficient computation of the intermediate positions.
