Embodiment 1

[0027] figure 1 The flowchart of the tool grinding method based on the numerical control system provided by the first embodiment of the present invention is shown, and only the parts related to the embodiment of the present invention are shown for convenience of description.

[0028] The tool grinding method based on the numerical control system provided in this embodiment includes:

[0029] Step S101 , setting a tool curve according to tool grinding requirements, and processing the tool curve in segments.

[0030] The tool curve is the path that the grinding wheel takes when grinding the tool. When grinding different tools, the tool curve is different, such as figure 2 As shown, assuming that a kitchen knife needs to be sharpened at present, the knife curve of the kitchen knife must be drawn first, and then the knife curve is divided into multiple segments. The specific segmentation is determined by the trend of the knife curve. Some, the subsections can be sparser in plac...

Abstract

The invention is suitable for the field of tool processing and provides a numerical control system-based tool grinding method, device and system. The method comprises the steps of: setting a tool curve according to a tool grinding demand, carrying out segment processing on the tool curve; obtaining position data of each segment point of the tool curve and recording in a numerical control system, and automatically carrying out spline teaching according to the position data and generating a tool processing program; and controlling a sand wheel for grinding a tool blank according to the tool processing program. According to the technical scheme, explorators are not needed in the technical scheme, so that the problems of high cost and difficulty in management due to multiple explorators are avoided, and after the tool processing program is generated, the program can be directly copied to other machines to complete volume production, when the size of a tool needs to be corrected, corresponding processing data is only needed to be corrected, and a new tool processing program is generated. According to the invention, the production cost is effectively lowered, the processing efficiency is high, the processing effect of the tool is excellent, and ground tool lines are jointed more smoothly and attractively.

Description

technical field [0001] The invention belongs to the field of tool processing, and in particular relates to a tool grinding method, device and system based on a numerical control system. Background technique [0002] The knife is made by grinding the knife blank. Specifically, it is ground on both sides of the knife blank, or it is directly ground with a mold with grooves, so that a wedge is formed between the back of the knife and the blade. The wedge-shaped area of ​​the blade should start from the handle until the tip of the knife is parallel to the contour of the entire knife. At present, the profiling method is generally used in grinding tools in the industry. "Profiling method" means that when grinding a tool, a mold cavity with the same dimensions as the tool must first be prepared. Usually, the mold cavity will take into account the interference of the grinding wheel, and then use the profiling device to make the grinding wheel follow the profile. The surface trajec...
