Around us, CNC machining is a very exquisite and complex technology, and it plays a very important role in CNC mold machining
If we want to master such a technology, there are many things we need to know and understand. For people who do not understand CNC machining, it is difficult to grasp that degree in operation and often encounter many difficulties.
In order to better operate and use, we need to master certain skills and knowledge. What are the main ones? The chief engineer of Sheng Technology came to share with you.
CNC machining is also called computer gongs, CNCCH or CNC machine tools. It is actually a kind of name from Hong Kong. Later, it was introduced into the Pearl River Delta of the mainland. It is actually CNC milling machine. In Guangzhou, Jiangsu, Zhejiang and Shanghai, it is called "CNC machining center". The range is extremely wide, and it has more advantages than other processing technologies. Important We have mastered the following skills to make the processing more smoothly.
1. The speed of the white steel knife should not be too fast.
2. For coppersmiths, use white steel knives less frequently, and more use flying knives or alloy knives.
3. When the workpiece is too high, you should use different length cutters to cut the thickness in layers.
4. After roughing with a big knife, use a small knife to remove the remaining material to ensure that the remaining amount is consistent.
5. Flat-bottomed knives are used to process planes, and ball knives are used less to reduce processing time.
6. When the copper worker cleans the corner, first check the size of the R on the corner, and then determine the size of the ball knife to use.
7. The four corners of the calibration plane should be flat.
8. Where the inclination is an integer, use an inclination knife to process, such as pipe position.
9. Before doing each process, think about the margin left after the previous process is processed, so as to avoid empty tools or excessive processing.
10. Try to take simple toolpaths, such as shape, grooving, one-sided, and avoid the surrounding height.
11. When walking WCUT, if you can go FINISH, don't go ROUGH.
12. When the shape of the light knife is rough, polish it first, then polish it. When the workpiece is too high, polish the edge first, then polish the bottom.
13. Set tolerances reasonably to balance processing accuracy and computer calculation time. For roughing, the tolerance is set to 1/5 of the margin, and for light knife, the tolerance is set to 0.01.
14. Do more procedures to reduce the time of empty knife. Do a little more thinking to reduce the chance of error. Do a little more auxiliary line auxiliary surface to improve the processing condition.
15. Establish a sense of responsibility and carefully check each parameter to avoid rework.
16. Diligent in learning, good at thinking, and continuous improvement. For non-planar milling, use more ball cutters, less end cutters, and don't be afraid of receiving the cutter; small cutters clean the corners and large cutters for finishing; don't be afraid to make up the surface. Properly making up the surface can increase the processing speed and beautify the processing effect.
