Flourish Legend Teaches You the Precautions of CNC Programming

There are many precautions for cnc programming. Wendy will share with you the common problems of cnc programming today: I suggest you collect them.

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

2. Copper workers seldom use white steel knives for rough cutting, but use flying knives or alloy knives more.

3. When the workpiece is too high, it should be roughed with different length cutters in layers.

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

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

6. When the copper worker cleans the corner, first check the size of 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 slope is an integer, it should be processed with a slope knife, such as the pipe position.

9. Before doing each process, think clearly about the remaining allowance after the previous process, so as to avoid empty cutting or excessive processing.

10. Try to use simple tool paths, such as shape, grooving, single side, and less contouring.

11. When going to WCUT, if you can go to FINISH, don't go to ROUGH.

12. When polishing the shape of the knife, first rough polish and then finish. When the workpiece is too high, first polish the edge and then polish the bottom.

13. Reasonably set tolerances to balance machining accuracy and computer calculation time. When roughing, the tolerance is set to 1/5 of the allowance, and when the light knife is used, the tolerance is set to 0.01.

14. Do a little more work to reduce the time of empty cutting. Do a little more thinking to reduce the chance of error. Make more auxiliary lines and auxiliary surfaces to improve the processing conditions.

15. Build a sense of responsibility and double check every parameter to avoid rework.

16. Be diligent in learning, good at thinking, and keep improving.

For non-plane milling, use more ball cutters, less end cutters, and don't be afraid of receiving cutters;

A small knife clears the corners, and a large knife is refined;

Don't be afraid to make up the surface. Appropriately make up the surface can increase the processing speed and beautify the processing effect.

High hardness of rough material: up milling is better

Low hardness of blank material: Climb milling is better

The machine tool has good precision, good rigidity, and finishing: it is more suitable for down milling, otherwise it is more suitable for up milling

Climb milling is strongly recommended for finishing inside corners of parts.

Rough machining: up milling is better, finish machining: down milling is better

The tool material has good toughness and low hardness: it is more suitable for rough machining (machining with large cutting volume)

Tool material has poor toughness and high hardness: it is more suitable for finishing (small cutting amount processing)
