NC programming learning needs to master the machining procedures of parts with complex shapes, non-circular curve contours, three-dimensional surfaces and so on. Using automatic programming method is efficient and reliable. In the process of programming, programmers can check whether the program is correct in time and modify it in time if necessary.
Because the computer replaces the programmer to complete the tedious numerical calculation work, it saves the workload of writing the program list, and the programming efficiency can be improved by dozens or even hundreds of times, which solves many programming problems of complex parts that cannot be solved by manual programming.

Matters needing attention in learning NC programming:
1, the speed of the white steel knife should not be too fast.
2. Less white steel knives are used in copper rough machining, and more flying knives or alloy knives are used.
3, the workpiece is too high, should be layered rough cutting with different lengths of knives.
4. After rough machining with a broadsword, remove excess materials with a knife, and then polish the knife to ensure the consistency of the allowance.
5. The plane should be processed with a flat knife, and ball end mill should be used less, which can reduce the processing time.
6. When the copper worker cleans the corners, first check the size of R on the corners, and then determine how big the ball knife is.
7. The four corners of the calibration plane should be horizontal.
8, where the slope is an integer, the application of slope knife processing, such as pipeline position.
9. Before each working procedure, think clearly about the remaining allowance after processing in the previous working procedure, so as to avoid empty knives or excessive processing.
10, try to take a simple cutting path, such as modeling, excavation, single side, about the same height.
