In this paper, a velocity connection algorithm of arbitrary multi-axis linkage is presented with regard to the problem of velocity connection efficiency of multiple straight-line paths in the motion control system. For this algorithm, with the velocity, acceleration and displacement of the current segment and the previous segment as constraint conditions, the acceleration is not set as a constant but the intersegmental velocity variable is set independently. The initial velocity and final velocity of each segment is solved on this basis, improving the movement efficiency and simplifying the calculation. Therefore, this algorithm is particularly suitable for the high-speed movement mechanism driven by a stepper motor. As for the actual motion track of the rapid prototyping machine, a comparison was made between this algorithm and the traditional velocity connection algorithm to verify the effectiveness of this algorithm.

Automatic Positioning

A high-precise automatic positioning system for data sample of linear time grating sensor is designed. In order to achieve linear time grating sensor of data sample, improve measure work efficiency, an ARM MCU is used as a major chip to control the stepper motor to rotate. In this way, the stepper motor drives the ball screw, the moving probe of linear time grating sensor and reading head of linear grating to move synchronously. A high-precision automatic positioning of the system hardware is designed. In addition, ARM controlling circuits and stepper motor driving circuits are designed. Therefore, the special communication interface is designed for the high-precision automatic positioning system, receiving the feedback signal from time grating sensor, forming a high-precision closed loop control system, and communicating with upper computer by serial. Experiment results prove that the positioning precision of control system can reach 0.1 um.
