1, cnc processing steps are too scattered
The reason for this problem is that it is afraid of complexity (referring to preparation time), simple programming, simplified operation processing, easy to adjust the knife with a knife, and accustomed to ordinary processing. This results in product quality (position tolerance) that is not easily guaranteed, and production efficiency does not work well. Therefore, cnc processing technicians and operators should be fully familiar with cnc machining knowledge, try more, grasp the relevant knowledge, use the method of process concentration as much as possible, and use it several times, which will naturally reflect its advantages. After the process concentration, the unit processing time increased. We arranged the two devices face to face, realizing one person to operate two devices, the efficiency was greatly improved, and the quality was well guaranteed.
2, cnc processing order is unreasonable
Some cnc processing operators often take into account some of the problems in preparation, and often arrange the processing order extremely unreasonable. CNC machining is usually processed according to the requirements of the general machining process. For example, the first coarse and then fine (changing the knife), first and then the outside, the reasonable selection of cutting parameters, etc., so that the quality and efficiency can be improved.Use G00 (G26, G27, G29) to quickly locate the command. The G00 command brings great convenience to programming and use. However, if it is improperly set and used, it will often cause adverse effects such as overshoot, zero precision, and strain on the surface of the device due to excessive speed setting. The zero return route is not noticeable, and it is easy to cause a safety accident that collides with the workpiece and equipment. Therefore, when considering the use of the G00 instruction, it should be considered in a comprehensive manner and should not be arbitrary.
In CNC machining, special attention should also be paid to enhancing the retrieval and commissioning of the program. After the program is input to the control system, the operator should use the SCH key and the ↑, ↓, ←, → move keys to make uncertainties and determine the search, and if necessary, modify the program to ensure the accuracy of the program. At the same time, before the formal execution of the program processing, the program must be tested (turn on the amplifier) to confirm whether the processing route is consistent with the design route.
The above are some common problems and solutions when using cnc processing equipment. There may be other problems in the actual work, but as long as the cnc processing engineering technicians and operators brainstorm and grasp the knowledge and skills related to numerical control, the numerical control equipment can best exert the maximum benefits for the enterprise.
