What do you usually learn in NC programming?
NC programming refers to the technology of controlling NC machine tools to process by computer programming. The learning content of NC programming includes:

1. Mathematical knowledge: CNC programming needs to master certain mathematical knowledge, such as plane geometry, solid geometry, trigonometric functions, vectors, etc. According to the established machining route and the allowable machining error of the parts, the data needed for input into the numerical control device is calculated, which is called numerical calculation. The main content of numerical calculation is to calculate the coordinate values of part contour and tool path in the specified coordinate system.

2. Mechanical knowledge: CNC programming needs to know the mechanical knowledge such as the structure, working principle and processing technology of CNC machine tools.

3. Programming language: CNC programming needs to master CNC programming languages, such as G code, M code and T code. According to the code and format specified by the numerical control system used, write the program.

4. Tool selection: NC programming needs to select the appropriate tool according to the shape and material characteristics of the machined parts.

5. Parts processing technology: The program can only be used after inspection, verification and trial cutting. Numerical control programming needs to know the technological process of parts processing, such as processing sequence, processing depth, processing speed, the use of cutting fluid and so on.

6. Programming software: CNC programming needs to use special programming software, such as MasterCAM, UG, Pro/E, etc.

7. Quality control: CNC programming needs to master quality control methods, such as detection, measurement and correction, to ensure the quality of machined parts.

In a word, NC programming needs to master a lot of knowledge, including mathematics, machinery, programming language, tool selection, machining technology, programming software and so on. In order to carry out effective numerical control programming.
