①View
The graphics include the unfolded part and the bent part of the workpiece. There is no corresponding three-view relationship between the two. Generally, "unfolded drawing" or "bending drawing" should be marked. Scale drawing, the drawing surface must be marked with hem marks and bending direction marks. j
②Layer color regulation
White - contour line (cutting line), green - dimension line, red - center line, light blue - filter line, yellow - thin line, the etching line must use a non-white layer, and mark " etching".
③ The development drawing stipulates that the intermediate tolerance is used to draw
For laser-cut workpieces, if the tolerance zone of the hole is less than 0.1mm, the hole is generally drawn 0.3mm (plate thickness ≤ 3mm)~0.5mm (plate thickness>3 mm) prema nominalnoj veličini i naznačiti maksimalnu veličinu veličine otvora za razvrtanje ili razvrtanje.
④Laser cutting
The size of the bottom hole of the thread cut by the laser is drawn according to the data in the table below. In addition to the actual size of the bottom hole, it should also be marked with "expanded MXX thread".
