What are the reasons for tool collision in CNC machining centers?

CNC machining center is a machining tool, and it is inevitable for different people to collide with knives due to misoperation and other reasons. If there is a collision, how to diagnose the cause of the collision? What are the common reasons for the collision? The following is a summary by Zhongyilong's editor of the causes of knife collisions in CNC machining centers. Only by knowing the cause of the knife collision can you accurately determine the fault of the knife collision in actual maintenance.

(1) Programming error

Process arrangement error, ignoring process relationships, incorrect parameter settings.

For example: 

A. The coordinate is set to the bottom of zero, but in reality, the top is 0;

B. The safety height is too low, resulting in the tool not being able to fully lift the workpiece;

C. The opening amplitude of two times is smaller than the previous one;

Analyze and check the path of the D program;

(2) Program memo error;

For example:

 A. Write unilateral numbers in four squares;

B. Incorrect marking of the protrusion distance or workpiece distance during vise clamping;

C. Missing or incorrect tool length or remarks, resulting in tool collision;

D. The program should be as detailed as possible;

E. The program should be based on the principle of "exchanging old for new": the order to destroy the old program.

(3) Tool measurement error;

For example: 

A. Tool data input does not consider the tool holder;

B.The knife is too short to fit;

C. Scientific methods should be used to measure tools and more accurate instruments should be used as much as possible;

D. The length of this knife should be greater than the actual depth.

(4) Program delivery error

Program number call error or program has been modified but still handled by the old program;

Detailed information on the inspection program that the processor must perform before processing;

The time and date of the program, as well as the simulation bear.

(5) Tool selection error;

(6) The blank exceeds expectations, the blank is too large, and the program is inconsistent with the blank.

(7) The hardness of the material itself is defective or too high

(8) Clamping factor, block interference, not considered in the program

(9) Machine malfunction, sudden power outage, lightning strike, knife collision, etc

The above reasons for tool collision in CNC machining centers are shared here. As a high-precision CNC machine tool, collision prevention is very necessary. Operators are required to develop a habit of being serious, careful, and cautious, and reduce the collision phenomenon of the machine tool according to the correct machine tool operation methods.
