CNC programming is the whole process from parts drawing to obtaining CNC processing procedures. Its main task is to calculate the knife point in the processing of processing. The knife point is generally taken as the point of the knife axis and the surface of the tool. The knife axis vector is also given during multi -axis processing.
CNC machine tools are in accordance with the requirements of workpiece pattern and processing process, and the movement, speed and action of the tools and components of each component, the main axis speed, the rotation direction of the main axis, the knife head clamping, the knife head and the cooling, etc. The prescribed CNC code forms a program form and enters into a special computer of the machine. After the CNC system compiles, calculates, and logically process it according to the instruction input input, various signals and instructions will be output to control each part of various shapes according to the prescribed displacement and sequential actions to process various different shapes of workpieces. Therefore, the preparation of programs has a great impact on the performance of CNC machine tools.
CNC machine tools need to enter the CNC device in the form of a program in the form of a program, and then send a pulse signal to control the operation of various motion components of the CNC machine tools to complete the part of the parts of the components.
With the advancement of technology, 3D CNC programming is generally rarely used by manual programming, while commercial CAD/CAM software is used. CAD/CAM is the core of a computer -aided programming system. The main functions include data input/output, calculation and editing of processing trajectory, process parameters, processing simulation, post -processing and data management of CNC program.
At present, software that is popular with users in my country is MasterCam, UG, Cimatron, Powermill, Caxa, etc. Each software is similar to the principles, graphics processing methods and processing methods of CNC programming, but each has its own characteristics.
