A method for automatic production of cutting dies capable of continuous processing

Abstract

The invention belongs to the field of numerical control machining, and particularly relates to an automatic production method of a die that can realize continuous machining. Use the CNC machine tool on-machine measurement system to measure the tools in the tool magazine, and store the measurement results and the tool numbers one by one. The coordinates of the contact point between the taper cutter and the workpiece in the machining path are calculated, and the actual point coordinates of the taper cutter are calculated to correct the theoretical tool path to generate a new machining path for actual machining. The invention is simple to operate, the whole process is completed in the CNC system of the machine tool, and there is no need to stop repeatedly, which ensures the continuity of production, effectively improves the machining accuracy and processing efficiency of the die, and can realize the automatic mass production of the die.

Description

technical field [0001] The invention belongs to the field of numerical control processing, and in particular relates to an automatic production method of a cutting die which can realize continuous processing. Background technique [0002] The die is a commonly used forming tool in the die-cutting industry, and is usually processed by a cone knife. In actual processing, due to the deviation between the theoretical tool and the actual tool, and the deviation value is not a fixed value, it will change with the change of the tool contact position, it is difficult to directly compensate the tool deviation in the machining path, so that the conical knife Over-cutting or under-cutting occurs when processing the cutting edge and the side of the cutting edge. In order to ensure the processing accuracy of the cutting die, the current solution is to measure the conical cutter after each tool change, and edit and generate a new processing path in the CAM software according to the actua...

Problems solved by technology

In actual processing, due to the deviation between the theoretical tool and the actual tool, and the deviation value is not a fixed value, it will change with the change of the tool contact position, it is difficult to directly compensate the tool deviation in the machining path, so that the conical knife Over-cut or under-cut phenomenon occurs when processing the cutting edge and the side of the cutting edge

In order to ensure the processing accuracy of the cutting die, the current solution is to measure the conical cutter after each tool change, and edit and generate a new processing path in the CAM software according to the actual measurement results of the current tool, and then input the processing path To process in the machine tool, this method needs to stop every time the tool is changed, especially in mass production, because the size of the cone cutter is difficult to keep consistent, it is necessary to perform the above operations on each tool involved in the processing, and there is no guarantee Process efficiency and continuity of production
