How to detect and record tool wear problems in CNC milling machines?

Nowadays, CNC milling machines have a wide range of uses in our lives, especially in industry. However, the detection record of the tool wear of CNC milling machines has always been A difficult question, below we introduce how to record tool wear on CNC milling machines.

In the past, people mainly used a magnifying glass integrated with a measuring ruler to inspect universal milling machines. Although it can improve the flexibility of measurement, differences in operators can lead to inconsistent measurement results. Similar results can be shown for another system under test: on the one hand, although the fixed measurement system has better economy, its portability is poor; on the other hand, the simple mobile measurement system has lower measurement accuracy and poor imaging quality. Poor, insufficient measurement depth. Nowadays, universal milling machines mainly use graphics to display the production efficiency of machining tools and the process of the wear scratch depth (VB) gradually deepening with the increase of service life.

After optimizing the processing process, the entire system can be put into a portable container and equipped with necessary spare batteries, chargers or cleaning tools. Structure of the measuring system: A digital camera equipped with a magnetic tripod is placed directly in front of the turntable milling cutter of the milling machine. Shanghai Weihong Electronics said: "The high quality of the images, the easy operation of the measuring system and the evaluation software are one of our great advantages. And we During the measurement process, users and tool manufacturers are repeatedly asked whether they need to provide them with an integrated measurement system package with software. ”

To date, the universal radial milling machine series has come from the aerospace industry, tool manufacturers. Technicians in the manufacturing and scientific research instrument industries have begun to apply this system in cutting processes. After inspecting and optimizing the measurement system, the functions are compact and practical:

1) User-friendly measurement software: The evaluation software Abrascan included in the wear measurement package can measure distance (D), angle (A) and radius. Click the "Spacer" icon to display the relevant dimensions in millimeters. Further distance and angle measurements can also be displayed in separate images. Click the right mouse button to copy the relevant data and save it as an Excel table file. This greatly simplifies the formation process of wear scratch width. Other auxiliary functions, such as brightness, contrast, grayscale, etc. are also available. Because the universal milling machine system is based on Office software, users can get started quickly without additional training.

2) Output the measurement value: The wear formation process can be generated by storing the measurement value in the X5036A vertical milling machine table calculation software. The extremely small signs of wear can be identified and measured using the wear measurement system Abrascan. Therefore, the tool can be optimized. The Abrascan image can show the wear formation process. The horizontal axis is the chip interval of the tool, in meters; the vertical axis is the wear scratch width VB, in millimeters; the three curves are tools A, B, and C respectively.

3) Turntable: Wear scratch width VB=0.136mm: The measurement process is as follows: Fix the digital camera on a magnetic tripod. The magnetic tripod can also be used to measure directly on the milling machine without removing it from the bracket or Remove the tool from the spindle. The X6132A horizontal milling machine has a display screen that can be rotated at will, allowing shooting at any position. Therefore, users only need to turn on the digital camera to take pictures at any time. Photography enthusiasts can of course fine-tune it according to different occasions. The rotary pump can transfer the stored images to a laptop via a USB cable and use the software for evaluation.

4) The measurement process is very simple: The first user of this system was very encouraged: "All the adjustment parameters have been stored on the camera - you can take clear and sharp photos within five minutes of opening the package. photo.
