In their own learning through the combination of precision, heat treatment, processing requirements, technical requirements (such as precision, flexibility) and other aspects of the comprehensive knowledge. In order to overcome the problems in the process of NC machining, it is necessary to master the operation skills of the general lathe and the traditional processing technology. Then the depth analysis of the processing parts, draw CAD and CATIA two-dimensional, three-dimensional drawings. Through the drawings can better reflect the shape of the processing parts and specific analysis of specific operating procedures. CAD is in one dimension inside the parts size, with clear performance in the drawings, during processing be clear, CATIA is in a three-dimensional space and a visual effect of parts fully unfolded, and can be on the computer through the translation, rotation of a series of view, operation that can be a won...
