The first, the tool concentrated sequence method.
The principle of this method is very simple, it is based on the tool used to divide the process, simply put, is to use one knife to finish all the machining procedures on the part, and then use a second knife, and then a third knife until all the machining procedures are completed. This processing method is to reduce the inconvenience caused by frequent tool change, can also speed up the overall progress of mechanical drawing processing, but also can reduce unnecessary positioning errors.
The second, rough and finish processing method. In simple terms, it is to do rough machining or semi-finishing of a single part first, and then finish the operation. Then, for a large number of parts, the first unified rough processing, and then semi-finishing, and finally complete the mechanical finishing work. We should pay special attention to the gap between rough and finish machining, and must be buffered for a period of time. This is to make the deformation of parts after rough machining fully recover time, and then finish machining after recovery, which can improve the machining accuracy of parts and increase the qualified rate of finished products.Line Cutting
The third, according to the processing parts of the sequential method.
This method is CNC parts processing, the first plane processing, and then drilling processing. It can also be explained that simple geometric shapes are processed first, and complex geometric shapes are processed later. That is, the first processing accuracy is low, and then the processing accuracy requirements are relatively high. In short, we in the CNC machine parts processing, parts processing process must be based on their own situation to specific analysis, see according to what kind of processing method is more suitable, and then mechanical drawings processing work.
We all know that CNC parts processing is in accordance with the needs of production to open the material, wait until the good material after the production of small parts, you can first go to punch processing, and then carry out the gong cutting or CNC processing. This method in the glasses accessories processing and auto parts production industry used more. But if the container is processed, it is necessary to first open the material punch and then burn bright, and then sand, oil injection, and finally assemble the accessories so that the finished products come out.
