Introduction to self-study of NC programming

The self-study method of Cnc programming introduction is as follows:

1, learn G code and M code: G code is the movement instruction of NC machine tool, and M code is the auxiliary function instruction. You can learn these instructions by reading related books or searching online.

2. Learn CAD drawing software: CAD drawing software can help you draw drawings of parts, so as to better understand the structure and shape of parts. Learn CAM software: CAM software can help you convert part drawings into numerical control programs. Commonly used CAM software includes Mastercam, UG, etc.

3. Practical operation: deepen the understanding and mastery of NC programming through practical operation. You can build a simple CNC machine tool at home or in the laboratory to practice.

4. Attend training courses or courses: If you want to master the skills of NC programming faster, you can consider attending training courses or courses. These courses are usually provided by professional training institutions, which can help you get started faster.

Relevant knowledge of NC programming

1, definition: CNC programming is a technology that uses computer programs to control CNC machine tools for machining operations. Programming language: NC programming uses two programming languages: G code and M code. G code is used to control the movement and position of the machine tool, and M code is used to control the function and operation of the machine tool.

2. Machine coordinate system: CNC programming uses machine coordinate system to define the position and shape of the machined parts. The machine tool coordinate system includes three axes of X, Y and Z and three axes of rotation of A, B and C. ..

3. Machining parameters: CNC programming needs to set various machining parameters, including cutting speed, feed speed and cutting depth. These parameters need to be reasonably selected according to the processing materials, tool types and processing requirements.

4. Machining strategy: NC programming needs to formulate appropriate machining strategies, including machining sequence, cutting path and cooling mode. Reasonable processing strategy can improve processing efficiency, reduce cost and improve processing quality.

5. Simulation and verification: The program of NC programming needs to be simulated and verified to ensure the correctness and reliability of the machining process. The simulation software can use simulation of machining process to check whether the tool path and cutting parameters are reasonable, and predict the possible machining problems and take measures to solve them in advance.

6. Tools and materials: the tools and processing materials that need to be considered in NC programming. Different cutting tools and materials need different cutting parameters and machining strategies. At the same time, it is also necessary to consider the tool life and replacement cycle, as well as the mechanical properties and heat treatment state of the material.
