A rapid direction change acceleration compensation system and method during high-speed machining, the system includes a feed shaft, a rapid direction change acceleration compensation device, a workbench and a control system, the rapid direction change acceleration compensation device is installed on the feed shaft, and the rapid direction change The acceleration compensation device is connected with the worktable, the feed axis, the rapid direction change acceleration compensation device and the control system are connected. The method is to provide an acceleration opposite to the current movement to the feed axis through the rapid direction change acceleration compensation device, so as to realize the acceleration during the machining process. The high-precision control of the rapid change of the workbench from high-speed motion to deceleration to rest, the invention has the advantages of safety, easy operation, low cost, and high accuracy.
Description
technical field [0001] The invention relates to the technical field of numerical control machining, in particular to an acceleration compensation system and method for rapid direction change during high-speed machining. Background technique [0002] High-speed and high-precision machining is the development trend in the field of CNC machining. During the process of high-speed and high-precision machining, the worktable moves at high speed under the drive of servo motor or linear motor to complete high-precision machining. However, due to the complexity of many high-tech products at present, their requirements for processing are getting higher and higher. In the process design, the worktable is often required to change direction rapidly during the high-speed moving process; while the worktable moves at a high speed in a certain direction. When controlling its rapid direction change, it needs to go through two processes, that is, decelerate from high-speed movement to rest, an...
