Problems solved by technology
On the existing vertical-horizontal conversion five-axis machine tool, the rotation speed of the CNC turntable is a fixed value, and it will not automatically adjust the acceleration or deceleration of the CNC turntable due to changes in the inertia of the workpiece. Therefore, both processing efficiency and processing accuracy are important. not ideal

The invention discloses a rotary table inertia self-adaptive control method for a vertical-horizontal conversion five-axis machine tool, and aims to find a more effective implementation scheme for numerical control rotary table rotation control. The method comprises the steps of building an equal-proportion rotary table model in a preset vertical-horizontal conversion five-axis machine tool based on the preset vertical-horizontal conversion five-axis machine tool; importing the rotary table model into a virtual debugging module; testing the rotary table model based on the established rotary table rotation test module, the virtual debugging module, the rotary table model and the load weight borne by the rotary table model to obtain a rotary table inertia-acceleration / deceleration data table; comparing the rotary table inertia-acceleration / deceleration data table with a preset rotary table inertia-acceleration / deceleration theoretical database, judging whether the difference between the two is within an allowable range, if so, importing the rotary table inertia-acceleration / deceleration data table into the preset vertical-horizontal conversion five-axis machine tool, so as to control the rotary table inertia of the preset vertical-horizontal conversion five-axis machine tool in a self-adaptive mode.
Description
technical field [0001] The invention relates to the field of numerically controlled machine tools, in particular to a method for self-adaptive control of the turntable inertia of a vertical-horizontal conversion five-axis machine tool. Background technique [0002] The CNC turntable is mainly used on the machine tool of the CNC machine tool machining center. For example, the CNC turntable in the vertical-horizontal conversion five-axis machine tool is a key component for the vertical-horizontal conversion five-axis machine tool to realize complex surface processing. The operation stability and rotation acceleration and deceleration of the CNC turntable play a vital role in the machining accuracy and efficiency of the workpiece. On the existing vertical-horizontal conversion five-axis machine tool, the rotation speed of the CNC turntable is a fixed value, and it will not automatically adjust the acceleration or deceleration of the CNC turntable due to changes in the inertia o...
