Description

technical field [0001] The invention belongs to the field of numerical control machining process optimization, and more particularly relates to a process optimization method of a winding machine based on double-code joint control and a winding machine. Background technique [0002] In the traditional CNC winding process, the G code will directly affect the speed planning of the CNC system, and the poor quality G code will often cause speed fluctuations in the processing process, resulting in poor processing efficiency, contour accuracy, vibration and surface quality. Therefore, a large number of substandard products are produced, resources are wasted, and the severe vibration of the processing process can even cause a certain degree of damage to the machine body. [0003] CNC machining is a relatively complex process, including the determination of the process plan and machining code in the early stage, and the optimization of process parameters in the later stage. The proce...

Problems solved by technology

The main cause of the feed speed fluctuation is the limitation of the interpolation algorithm. The traditional CNC system only provides linear and circular interpolation. For simple curves such as straight lines and circular arcs, linear and circular interpolation can be fitted. Very good, it can meet the processing requirements; but for complex curves that are not straight lines and arcs, if a straight line or arc is used to approximate, the result is an approximate value of the theoretical processing path, resulting in a difference between the theoretical feed rate and the actual feed rate. Fully consistent, resulting in feed rate fluctuations

Feed speed fluctuations will bring many difficulties and hazards to processing, such as large acceleration and jerk leading to tool vibration, making the processing path not smooth, and reducing the processing quality level of the workpiece
