Tool procurement and recruitment

In the machining industry, it is very important to evaluate the reasonable life of tools, because it can help control production costs, improve production efficiency and ensure product quality. The following are some common methods to evaluate the reasonable life of tools:

1. Increase cutting time: record the total running time of the tool in cutting operation, usually in minutes. By comparing the running time with the tool life guide provided by the tool manufacturer, the reasonable life of the tool can be evaluated. If the machinability is normal after the set time, the normal time can be increased by 5%- 10%, and the reasonable time life can be evaluated after several cycles.

2. Tool wear and damage: regularly check and evaluate the degree of tool wear and damage. If the tool surface is worn too much, there are obvious gaps on the blade or cracks begin to appear on the blade. This may mean that the tool needs to be replaced, and it also means that the tool has reached its service life under the current machining parameters. At the same time, the life should be recorded by the number of workpieces and the processing time.

3. Cutting force and power consumption: evaluate the condition of cutting tools by monitoring the changes of cutting force and power consumption. When the tool is worn or damaged, the cutting force and power consumption will usually increase (usually called cutting resistance, at this time the cutting resistance will become larger, and there will be a feeling of immobility, which is manifested in the loud noise of the machine tool or the vibration of the spindle of the machine tool). Measuring cutting force and power consumption regularly and comparing them are helpful to determine when the tool needs to be replaced.

4. Product quality: Tool wear or failure may directly affect product quality. By monitoring the key indexes such as dimensional accuracy and surface quality of products, we can evaluate whether cutting tools affect product quality. If quality problems are found, you may need to consider replacing tools.

Based on the pain point of tool site management and optimization in machining enterprises, Suzhou Novell cooperates with manual services (new product tool configuration, technical training, etc. ) to solve the whole link problem from putting forward production and processing requirements to tool procurement, warehousing, distribution, recycling, sorting and scrapping. Among them, the self-developed knife doctor system can not only help knife enterprises to regularly check and supervise whether the tool life is reasonable through the above four aspects, but also track the whole life cycle of each tool, including the recovery, polishing, reuse and scrapping of the tool.
