The invention relates to a method for realizing processed coordinate transition in numerical control system. The method comprises the following steps: the system acquires a position parameter of a workpiece to be processed based on a mechanical coordinate system; a workpiece coordinate system is generated according to the obtained position parameter of the workpiece to be processed; a processing parameter based on the workpiece coordinate system is converted to the processing parameter based on the mechanical coordinate system; then, the numerical control system processes the workpiece according to the processing parameter based on the mechanical coordinate system. By using the method of the invention, the numerical control system can convert the processing parameter based on the workpiece coordinate system to the processing parameter based on the mechanical coordinate system so that the processing can be completed under the condition of not moving the workpiece position. Work of adjusting the workpiece position can be omitted. Time, manpower and material resources needed during the processing can be saved. Therefore, production efficiency of using the numerical control system can be greatly raised.
Description
technical field [0001] The invention relates to the technical field of numerical control systems, in particular to the technical field of coordinate management methods in numerical control systems, and specifically refers to a method for realizing machining coordinate conversion in numerical control systems. Background technique [0002] In the existing numerical control system, the coordinate management method is usually a simple addition and subtraction of the offset. The direction of the XY axis of the workpiece coordinate system is fixed, which is consistent with the machine coordinate system of the CNC system. However, in the actual processing process, the workpiece often has a certain deflection angle. In order to improve the utilization rate of raw materials, when using such a workpiece, it is necessary to manually move the raw material to make the deflection angle correspond to the XY axis direction of the mechanical coordinate system. However, in the field of metal...
