Detecting tool wear of CNC milling machine

Since the CNC milling machine has been widely used in our lives, especially in the industry, how to record the degree of wear on the CNC milling machine tool has always been a problem. The following describes 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 economy, 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) as the service life increases.

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 pictures, the measurement system, and the ease of manipulation of the evaluation software are our upper hand. And we In the course 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 instrumentation industries have begun to apply this system in the cutting process. 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, measures the distance (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 the need for 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 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.
