cnc machining technology is an application technology accompanied by the emergence of cnc machine tools, continuous development and gradually improvement. The direct study objects are the numerical control equipment CNC devices, control systems, numerical control procedures and preparation methods. CNC machining process comes from the traditional processing technology. It combines the traditional processing technology, computer numerical control technology, computer-aided design and auxiliary manufacturing technology. When the programmers receive a NC programming task of one component or product, the main works include:
1, CNC machining process feasibility study in accord with design drawings and related technical documents , to determine the CNC machining parts processing methods;
2, Select the type of CNC machine tools and the specifications;
3, Select the fixture and its supporting tools;
4, Select the tool and tool clamping system;
5, CNC machining programs and process planning;
6, Determine the processing area;
7, Design of CNC machining process content;
8, Coding CNC programs;
9, NC program debugging and process validation;
10, Finally complete all the NC process file and archive all the documents.
CNC programming can be from the beginning of the comprehension of the design drawings to the completion of coding the NC process.
