Abstract

The invention discloses a forward-looking self-adaptive speed control method of high-speed numerical control equipment. The numerical control system of the method conducts a plurality of layers of pre-reading decoding processing, uses pre-reading program segment information for pre-calculation to the terminal speed of a segment to be processed, adjusts a speed acceleration and deceleration time constant according to the calculation result, selects a speed acceleration and deceleration curve type, and then conducts a fast speed acceleration and deceleration calculation to an S curve so as to lead the numerical control equipment to process the micro-segments with high speed and smooth operation. The forward-looking self-adaptive speed control method comprises the following steps of: the pre-calculation of the terminal speed of the segment to be processed, the self-adaptive selecting strategy of the speed acceleration and deceleration time constant, and the speed acceleration and deceleration curve type; and the fast speed acceleration and deceleration calculation of the S curve. The invention provides a self-adaptive speed acceleration and deceleration control method for the high-speed numerical control equipment, leads the numerical control equipment to have the capacity of processing the micro-segments with high speed and smooth operation, and satisfies the speed control requirements of high-speed high-precision numerical control equipment.

Description

technical field [0001] The invention belongs to an adaptive acceleration and deceleration control method for numerical control equipment, in particular to a forward-looking adaptive speed control method for high-speed machining of small line segments. Background technique [0002] At present, complex surface machining is often approximated by small straight line segments generated by CAM software. Most of the lengths do not exceed 1mm (minimum 0.1mm). min, acceleration up to 9.18-2*9.18m / s 2 . The conventional acceleration and deceleration method takes each small path segment as the research object, and makes the initial and end speeds of each segment zero. This method will cause frequent system start and stop, slow speed, low efficiency and poor processing quality. Therefore, it is necessary to solve the problem of smooth transition of processing speed between small line segments. [0003] Some existing processing control methods for small line segments only consider th...
