The invention discloses a method for accurately stopping a spindle of a numerical control machine tool. The method comprises the steps that a programmable logic controller (PLC) system receives an accurate stopping instruction and sends the accurate stopping instruction to a numerical control system; the numerical control system judges whether the spindle is accurately stopped for the first time or not, if the spindle is accurately stopped for the first time, the trigger position gap of a zero point detection device is calculated according to trigger positions of the zero point detection device, the trigger positions of the zero point detection device are latched, the trigger position gap is stored, and if the spindle is not accurately stopped for the first time, the spindle is accurately stopped according to the trigger positions and the trigger position gap of the zero point detection device. According to the method, a gap existing in triggering in two directions of the zero point detection device is selected, so that the machining efficiency is improved while the accurate stopping precision is improved on the premise that the spindle does not need to move from the preset direction to the zero point detection device to perform zero point position triggering in each time of accurate stopping.
Description
technical field [0001] The invention relates to the technical field of spindle control, in particular to an accurate stop method for a spindle of a numerically controlled machine tool. Background technique [0002] During the working process of a machine tool with a gear-driven mechanical spindle, the spindle needs to stop rotating when processing methods such as boring or changing tools. In the spindle accurate stop method in the prior art, the spindle end is installed with an incremental encoder with a Z pulse mark that rotates 1:1 synchronously with the spindle. When the M19SX command is executed, the spindle servo receives the precise stop from the CNC system. Signal ORT, the spindle speed becomes the preset accurate stop speed, by finding the encoder Z pulse position, then switch the closed-loop control of the spindle, and stop accurately according to the preset parameter direction and angle based on the Z pulse. [0003] The precision machining efficiency of this spin...
