Nowadays, CNC milling machines have a wide range of uses in our lives, especially in the industry. However, it has always been a difficult problem to record the degree of wear on tool wear of CNC milling machines. Experts came to us about how to record the tool wear of the CNC milling machine.

In the past, people used the magnifier integrated with a measuring rule to perform universal milling machine inspection. Although they can improve the flexibility of measurement, the differences in operating staff will lead to inconsistent measurement results. Similar results can show another kind of system under test: On the one hand, although the fixed measurement system has better economics, but the portable function is poor; on the other hand, the simple mobile measurement system has low measurement accuracy and imaging quality. Poor, insufficient depth of measurement. Nowadays, universal milling machines mainly use graphics to show the production efficiency of machining tools, and the process of gradually increasing the wear scratch depth (VB) along with the increase of service life.

The process is optimized to fit the entire system into a portable container and equipped with the necessary battery backup, charger or cleaning kit. Construction of the measurement system: A digital camera equipped with a magnetic tripod is placed directly in front of the milling cutter of the milling machine. Shanghai Weihong Electronics, said: “The high quality of the picture, the measurement system, and the ease of use of the evaluation software are our upper hand. And we In the process of measurement by the user and the tool manufacturer, it is repeatedly asked whether they need to provide an integrated measurement system package with software."

So far, the universal rocker milling machine series of technicians from the aviation industry, tool manufacturing and scientific instrument industries have begun to apply this system in cutting processing. The inspection and optimization of the measurement system is compact and practical:

1) Measurement software that is user-friendly: Abrascan, the evaluation software included in the wear measurement package, can measure the interval (D), angle (A), and radius. Click the "Interval" icon to display the relevant dimensions in millimeters. You can also display more interval and angle measurements in a single picture. Right-click to copy the relevant data and save it as an Excel spreadsheet file. This greatly simplifies the formation of wear scratch widths. Other auxiliary functions such as brightness, contrast, grayscale, etc. are also available. Because the universal milling machine is based on Office software, users can quickly get started without having to participate in additional training.

2) Output measurement value: The formation of the measurement value in the X5036A vertical milling machine table calculation software can generate the wear process. With the Abrascan wear measurement system, extremely small wear marks can be identified and measured. So you can optimize the tool. Abrascan's image can show that the horizontal axis of wear is the chip spacing of the tool in meters, and the vertical axis is the wear scratch width, VB, in millimeters; the three curves are cutters A, B, and C, respectively.

3) Turntable: wear scratch width VB=0.136mm: The measurement procedure is as follows: The digital camera is fixed on a magnetic tripod, and the use of a magnetic tripod can also directly measure the length of the milling machine without removing the tool from the bracket or the spindle. The X6132A horizontal milling machine has an arbitrarily rotatable display that allows you to shoot anywhere. Therefore, users only need to open a digital camera to shoot at any time. Photographers of interest can, of course, fine-tune on different occasions. Rotary pumps can transfer stored images to a laptop via a USB cable and use software to evaluate them.

4) The measurement process was very simple: The first user of this system was greatly inspired: "All the adjustment parameters have been stored on the camera - a clear and sharp picture can be taken five minutes after opening the package.

Through the above introduction of Shanghai Weihong Electronics experts, you must have a good understanding and understanding of the record of the tool wear of CNC milling machine! Hope that these knowledge can help you to improve the relevant knowledge.

The development direction is based on the foam model required for solid casting. CNC machining has the advantages of even and accurate margins and good overall appearance of the mold. Starlight CNC is the earliest and most mature enterprise in domestic production model CNC machine tools. Jinan Xinghui CNC has participated in drafting. Some of the articles of association that amend the technical standards for China's solid foundry industry are the leading companies in the Chinese model CNC machine tool industry. Starlight CNC manufactures model CNC machine tools according to the idea of ​​metal cutting machine tools. The important machining parts of the machine tools have been subjected to annealing and other heat treatment processes. After processing is completed, coordinate measurement is performed to ensure the accuracy of the parts. The whole process of foam processing will be the direction of future development. Of course, there are many technical issues in this area that require further exploration and research.

Development goals In 2012, the development goals of the “12th Five-Year Plan” for the machine tool industry have been clearly defined, and high-end CNC machine tools will become the focus of future development. According to the development goals, in 2012-2016, China will move forward steadily toward a powerful machine tool industry, and the industrial structure will be significantly improved. 80% of domestic machine tools will meet the needs of domestic engineering projects, and the market share of CNC machine tools will reach over 70%.
