Why does the machine tool encounter tool collision? The problem lies here!

The matter of machine tool collision with knives can be said to be big or small, it's really not small. Once a machine tool collides with a tool, it can instantly turn tens of thousands of cutting tools into scrap. Don't say I exaggerate, this is the truth.
A machine tool worker in a company lacked operational experience and accidentally collided with a tool, resulting in a broken and scrapped imported tool in the factory. Although the factory does not allow workers to compensate, such losses are also heartbreaking. Moreover, machine tool collision not only causes the tool to be scrapped, but the vibration generated by the collision may also have adverse effects on the machine tool itself, and even lead to a decrease in machine tool accuracy.
So, never ignore the impact knife. In machine tool operation, understanding the causes of tool collision and preventing it in advance will undoubtedly greatly reduce the probability of tool collision.
The causes of tool collision in machine tools can be roughly divided into the following categories:
1, Program error
Nowadays, the level of machine tool CNC is very high. Although CNC technology has brought many conveniences to machine tool operation, there are also hidden dangers, such as tool collision incidents caused by programming errors.
There are several situations where program errors can cause knife collisions:
1. It is a parameter setting error that causes errors in the process acceptance, resulting in tool collision;
2. The collision occurred due to an error in the program note, resulting in incorrect program input;
3. It's a program transfer error.
Simply put, it is a situation where the program is re entered or has been modified, but the machine still runs according to the old program, resulting in a knife collision.
The collision caused by program errors can be avoided from the following aspects:
1. Check the program after writing to avoid parameter errors.
2. Timely update the program list and conduct corresponding checks and verifications.
3. Before processing, check the detailed data of the program, such as the time and date of program writing, to ensure that the new program can run normally before proceeding with processing.
2, Improper operation
Improper operation leading to tool collision is one of the important reasons for tool collision in machine tools. This type of tool collision caused by human error can be roughly divided into the following categories:
1. Tool measurement error. An error in tool measurement caused a mismatch with the machining, resulting in tool collision.
2. Tool selection error. In the process of manually selecting cutting tools, it is easy to overlook the machining process and choose tools that are too long or too short, resulting in tool collisions.
3. Hair embryo selection error. When selecting the processing embryo, the actual processing situation was not considered, and the embryo was too large or collided with the tool due to not matching the programmed embryo.
4. Clamping error. Improper clamping during the machining process can also lead to tool collision.
The collision caused by human factors can be avoided from the following aspects:
1. Choose reliable tool measuring instruments and methods.
2. After fully considering the machining process and the rough situation, choose the cutting tool.
3. Before processing, select the rough embryo according to the program settings and verify the size, hardness, and other data of the rough embryo.
4. The clamping process should be combined with actual processing conditions to avoid operational errors.
3, Other reasons
In addition to the above situations, some other unexpected situations may also cause the machine tool to collide with the tool, such as sudden power outage, machine tool malfunction, or defects in the workpiece material, etc. For such situations, it is necessary to take preventive measures in advance, such as regular maintenance of machine tools and related facilities, strict inspection of workpieces, etc.
Machine tool collision is not a trivial matter, being careful and cautious is the magic weapon. Understanding the causes of tool collision in machine tools and taking targeted preventive measures based on actual processing conditions, I believe even beginners can handle it with ease.
