To express the structural shape of a part clearly and completely, the key lies in selecting the appropriate three views. To determine the primary view for shaft-type parts and disc-type parts, it is generally done by considering their position of operation. To determine a view, generally two dimensioning references should be selected. Determining the dimensions of the 04 part drawing is an important basis for machining and inspecting the parts. According to the GB 05 standard, the projection of the root diameter of the thread along the axis is represented as a circle drawn with a thin solid line. The actual size of part 06 is the true size of the part. If it is determined that the actual size of a certain part in 07 is exactly equal to its nominal size, then this part is definitely qualified. It can be determined that the dimension deviation for size 08 can be negative, positive, or zero. It is determined that the tolerance for size 09 cannot be negative, but it can be positive or zero. Judgment 10: Since the maximum allowable dimension of the part is greater than the minimum allowable dimension, the absolute value of its upper deviation is greater than the absolute value of its lower deviation.
