What problems will be caused by improper processing and layout of CNC parts machining? Using cnc processing equipment for processing has high power and good quality, but if the process planning is not properly arranged, its advantages cannot be well reflected. From the experience of some CNC processing plants, there are some problems as follows:
1. The machining process of cnc parts is too loose
The reason for this problem is that it is afraid of complexity (referring to the preparation time), the programming is simple, the operation and processing are simplified, it is easy to adjust the tool with one knife, and I am used to ordinary machining. As a result, product quality (orientation tolerance) is not easy to guarantee, and production efficiency cannot be fully utilized.
Therefore, CNC machining technicians and operators should have a comprehensive understanding of CNC machining knowledge, do more inspections, master relevant knowledge, and try to use the method of process convergence for processing. After the selection process converges, the unit processing time increases. We put the two devices face to face, and one person completes the operation of the two devices, the power is greatly improved, and the quality is also guaranteed.
2. The processing sequence of cnc parts is unreasonable
Some CNC processing operators often arrange the processing sequence in an extremely unreasonable manner considering some problems in the preparation. CNC machining is usually processed according to the requirements of general processing technology, such as rough first and then fine (tool change), first inside and then outside, reasonable selection of cutting parameters, etc., so as to ensure quality and efficiency and improve.
Use the G00 (G26, G27, G29) quick positioning command with caution. The G00 command brings great convenience to programming and application. However, if the setting and application are improper, it will often lead to negative consequences such as zero return overshoot, accuracy drop, equipment guide rail surface strain due to excessive speed setting. If you do not pay attention to the zero circuit, it is easy to cause a safety accident that collides with the workpiece and equipment. Therefore, when considering using the G00 command, it should be considered carefully and not arbitrarily.
In CNC machining, special attention should be paid to strengthening program retrieval and trial operation. After the program is input into the control system, the operator should use the SCH key and the \u2191, \u2193, \u2190, \u2192 movement keys to search for uncertainty and confirmation, and modify the program if necessary to ensure the accuracy of the program. At the same time, before the program processing is officially executed, it is necessary to pass the program test run (turn on the power amplifier) to confirm whether the processing road is consistent with the planned road.
The above are some common problems and solutions when using CNC processing equipment. There may be some other problems in the actual work, but as long as the CNC machining engineering technicians and operators work together to earnestly master the knowledge and skills of CNC, the CNC equipment can bring great benefits to the enterprise.

With the continuous development of our technology, of course progress requires certain processing methods to be processed, otherwise it cannot be processed, and the same is true for CNC processing, so what is the acceleration and deceleration control of CNC parts processing?
1. Basic concept of flexible acceleration and deceleration control
In CNC parts processing, the special automatic acceleration and deceleration control function is generally completed directly by the system program flow. Under this method, the system needs to change the acceleration and deceleration characteristics or the addition and subtraction control to change the program flow of the CNC machine tool, so ordinary users cannot make the CNC machine tool have good acceleration and deceleration performance according to their own intentions. Therefore, the flexible acceleration and deceleration control method proposed by everyone adopts the basic principle of database query, divides the acceleration and deceleration control into two parts: acceleration and deceleration description and execution, and separates the acceleration and deceleration description from the system program flow. In the CNC machine tool software, a universal control safety channel is designed that is irrelevant to the query content of the acceleration and deceleration database.
2. Flexible automatic speed up control
Set the acceleration curve, the analysis curve and the non-analysis curve, and store them in the acceleration and deceleration curve library file in the form of a number table as a template.
3. Flexible automatic deceleration control
To speed up the control, store it in the acceleration/deceleration curve library file in the form of a number table as a template. Effective automatic acceleration and deceleration control is a key step to ensure the dynamic performance of CNC lathes. The traditional automatic acceleration and deceleration control based on a fixed curve lacks flexibility, it is not easy to ensure that the acceleration and deceleration process cooperates with the performance of the CNC machine tool, and the dynamic characteristics of the movement of the CNC machine tool cannot be optimized.
