For example, if a section of linear displacement needs to be generated along the V-axis direction, only the speed of the first servo motor needs to be adjusted, and when the first servo motor moves to a specified position, the rotational angular velocity of the inner shaft driven by the first servo motor is adjusted to be consistent with the angular velocity of the C-axis and the direction is the same, while the second servo motor always keeps the original motion angular velocity (consistent with the angular velocity of the C-axis and the direction is the same); (2) if the planar two-dimensional motion is to be realized, the rotation speeds of the first servo motor and the second servo motor need to be adjusted at the same time.
The electrolytic boring and milling process of the machine tool in the embodiment comprises the following steps: the control system controls the movement of the Z-axis, the C-axis, the U-axis and the V-axis, when the cathode of the tool is close to the tool, the electrolyte pump sends electrolyte from the cell to the cathode of the tool, the processing power supply is turned on, the workpiece rotates relative to the cathode of the tool, the part of the workpiece, which is opposite to the cathode of the tool, is removed by electrolytic processing, and the relative movement of the U, V axes is followed, so that the required shape is processed.
In the embodiment, because the cutting force is small in the micro-milling process of the electrolytic machine, the transmission part of the shaft U, V of the machine tool does not need to transmit excessive torque, and the transmission part does not need to adopt large size parameters.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
