Tool change method

Abstract

The invention discloses a tool change method. The tool change method comprises the following steps: S1, establishing XY-axis coordinate information, and obtaining groove position information of a toolto be changed; S2, determining the position of a cutting groove; S3, determining the position of a chip removal groove; and S4, inputting the parameters of the cutting groove and the chip removal groove into a grooving machine tool, and carrying out grinding machining on the cutting groove and the chip removal groove through the grooving machine tool to form a new tool body. According to the method, on the basis of a cutting edge of an old tool, and in the case that the positions of the two grooves are unchanged, a new cutting edge is further machined, so that the utilization rate after toolchange is increased; and the diameter range of the tool change is changed to be 1.9mm and below from the original tool diameter of 2.0mm, however, the diameter range can only be changed to be 1.4mm and below in the existing method.

Description

technical field [0001] The invention relates to the field of cutting tools, in particular to a method for changing the cutting tool. Background technique [0002] With the development of the manufacturing industry, the use of cutting tools is growing rapidly. In order to cope with the consumption of resources and the rise in raw material prices, it is necessary to recycle waste cutting tools to make full use of resources, reduce manufacturing costs, and reduce environmental pollution. . [0003] Taking the milling cutter for processing PCB as an example, the blade of the milling cutter wears out after being used for a period of time. There are two recycling methods in the existing technology. The production method is to cut off the blade part, and then remake the blade on the handle part, but this method makes the overall length of the knife shorter, which is inconsistent with the milling cutter; [0004] 2.

[0003] Taking the milling cutter for processing PCB as an example, the blade of the milling cutter wears out after being used for a period of time. There are two recycling methods in the existing technology. The production method is to cut off the blade part, and then remake the blade on the handle part, but this method makes the overall length of the knife shorter, which is inconsistent with the milling cutter;

[0004] 2. It is also possible to grind all the blades on the original surface to form a smooth rod, and then process the smooth rod, but this method reduces the overall diameter and reduces the specifications of the milling cutter.
