Embodiment Construction
[0050] The present invention will be further described in detail below in conjunction with the accompanying drawings.
[0051] like figure 1 A method for controlling repetitive positioning of a laser microtexturing machine tool is shown, including the following steps:
[0052] Step 1. Obtain the configuration information of the machine tool workbench, the configuration information includes the motion trajectory, speed and acceleration of the machine tool workbench;
[0053] Step 2, establishing a mathematical model of the transmission link of the machine tool, and calculating the ideal values of the rotational speed and acceleration of each servo motor in combination with the configuration information;
[0054] Step 3. Read the actual values of the speed and acceleration of each servo motor and compare them with the ideal values to obtain the setting parameters of the composite feedforward compensation of speed and acceleration, and obtain the feedforward compensation v...
