An Ultimate Guide to Hire Best CNC Machining Company

Is it possible to operate a CNC machine without colliding?

Analyzing the consequences caused by a collision on current CNC Machining China centers, and the resources they provide to prevent this accident, it can be said with certainty that it is.

Why do collisions occur? 

 A collision occurs when the operator of the machine releases a movement that he considers to be under control. Most collision cases occur in one of the following situations:

For various reasons, there may be an interruption in the processing of the program, such as:

  • power interruption

  • tool supervision

  • Correction of the program, etc., or with the action of the “reset” key. With this, basic functions are restored.

Can a collision be avoided?

If we consider that we can act in a protected manner in situations 1 to 4, that machine defects can be predicted with preventive maintenance, we practically eliminate all possibilities of collision.

The acquisition of a CNC machine and its operation is an act of great responsibility. Therefore, the CNC Machining China operator must be well trained and very well paid to perform this task. "Operating a CNC machine is like driving a car. You shouldn't be afraid, but be very careful and attentive. The operation is like mathematics, an exact science that does not admit mistakes".

In most cases of collisions, they happen and should be avoided in one of the following situations:


Collision with movements in JOG - Movement in JOG is a manual movement, selecting a certain axis to be moved. By selecting a specific key (X / Y / Z / B / C ...), and then by pressing keys that indicate the direction of the axis (+/-), movement in the indicated direction occurs.

 The collision occurs when there is a distraction from the operator who ends up pressing the inverted direction.


Several precautions are needed at this time. When moving an axis, the operator must pay close attention to where it is moving, and if there is any obstruction that could cause a collision. Making a move in JOG without this care is the same as driving a car looking sideways. It's a collision for sure!


Program Test at CNC Machining China -There are two situations of program processing that can be considered in risk testing.

The first case is when the program is brand new, where all sentences are processing at the test level. In this situation, when processed, the program is considered a risky situation from the first to the last sentence.

Another case is when a program, already tested and approved previously, that is working in production operation, for some reason receives a change, from a simple word to several sentences.


The execution of a program must be done with the same care, both in a "new" program and in an "altered" one. When dealing with a new program, the precautions described below must be observed from the first to the last sentence in execution. In the changed program, this care is restricted to the region where there are altered sentences.

DANGER 3 - Cycle Resumption

When a program is being processed at CNC Machining China centers, several modal actuation functions are being memorized.

The performance characteristics of a modal function become valid for the programmed protocol.

Several reasons can cause the interruption of the program processing, such as power interruption, tool supervision, and program correction.


 When interrupting the cycle, the parts must be immediately removed as far as possible. The resumption must be done in a specially chosen sentence, where the machining can be continued without any damage to the process.

DANGER 4 - Tool Replacement in the Process

During automatic cycle production, tool wear or breakage usually occurs and must be replaced. When the reserve tool is put into operation, it becomes a risk element, as there may be an error in the correction data feed for its geometric procedures.

In this case, when approaching the tool to the part, or the device, there will be a collision of the tip of the tool, which is considered minor, but in reality, it is greater than expected.


If a process tool wears out or breaks, it must be replaced by another similar part to perform the same job.
