What are the advantages and disadvantages of CNC machining?

　　CNC CNC machining has the following advantages:

　　①Reduce the number of tooling by a large amount, and do not need complicated tooling to process parts with complex shapes. If you want to change the shape and size of the part, you only need to modify the part processing program, which is suitable for the development and modification of new products.

　　②The processing quality is stable, the processing accuracy is high, and the repeating accuracy is high, which is suitable for the processing requirements of the aircraft.

　　 ③ The production efficiency is higher under the conditions of multi-species and small batch production, which can reduce the time for production preparation, machine tool adjustment and process inspection, and the cutting time is reduced due to the use of the optimal cutting amount.

　　 ④ It can process complex profiles that are difficult to process with conventional methods, and even process some unobservable parts.

　　CNC is also called a computer gong, CNCCH or CNC machine tool. It is actually a name from Hong Kong. Later, it was introduced into the Pearl River Delta in the mainland, which is actually a CNC milling machine.

　　 is a new type of processing technology, whose main job is to compile processing procedures, that is, to convert the original manual to computer programming. Of course, experience in manual processing is required.

　　CNC, also known as machining center, has a wide range of applications and is not limited to furniture production. Therefore, the summary of the experience of CNC use in various industries is worth learning. The following points are summarized:

　　 1. The speed of the white steel knife should not be too fast.

 cnc processing

　　 2. The copperworker uses less white steel knives for roughing, and more often uses flying knives or alloy knives.

　　3. When the workpiece is too high, it should be layered with a knife of different lengths.

　　 4. After roughing with a large knife, use a small knife to remove the remaining material to ensure that the remaining amount is the same.

　　 5. The plane should be processed with a flat-bottom knife and less ball cutters to reduce the processing time.

　　 6. When the copperworker clears the corner, first check the size of R on the corner, and then determine how big the ball cutter is.

　　 7. The four corners of the school plane must be flat.

　　 8. Where the slope is an integer, it should be processed with a slope cutter, such as pipe position.

　　 9. Before doing each process, think about the remaining amount after processing in the previous process to avoid empty knife or excessive machining.

　　 10. Try to use a simple tool path, such as shape, digging, one side, less walking around the height.

　　 11. When walking WCUT, if you can take FINISH, don't take ROUGH.

　　 12. When the shape of the light knife, first rough, then finish, when the workpiece is too high, first light edge, then light bottom.
