When out of the process bending process diagram, bending this step is very good to understand；
If you are a novice in bending, you should pay attention to the following points before using the bending machine:
1, distinguish between the first perspective or the third perspective, generally there are symbols in the picture box.
The first Angle of view is commonly used in China, according to the law of projection; The third Angle of view is placed on the left side of the screen. Exactly the opposite
2, do not miss the local view or section view, the edges and corners of the drawing must be seen in a bending schematic diagram than three views,
most are represented by lines or plate thickness line, usually you just have to clear down or up folding
3, put the bending workpiece according to the main view, pay attention to the direction of drawing or burr, easy to identify the direction, and easy to check whether the drawing is correct.
4, to see the sheet metal processing drawings bending line, is a solid line or dashed line. The solid line is the visible part,
which is bent up; The dotted line refers to the part that is not visible, that is, bending down.
5, sheet metal processing drawings are a lot of three-dimensional software, so sometimes the bending line has a tangent line to cover the dotted line.
So that we can not see the bending up or down, then with the side view to see the bending direction.
