The runout symbol in GD&T is represented by a circle with two parallel lines running through it. This symbol is used in engineering drawings and CAD models to specify the allowable runout of a surface or feature relative to a datum axis or plane. The runout symbol is often encountered in two primary contexts: circular runout and total runout.
The welding symbol consists of a basic symbol and leader, and additional symbols such as an auxiliary symbol, supplementary symbol, and weld size symbol can be added if needed. The scale, size, and representation method of the graphic symbols should comply with GB/T 12212.
Even though blind holes machining can be challenging, below are some helpful tips: Utilize a drill press in machining blind holes. It offers better control and accuracy throughout the drilling process. Choose the proper drill bit for your drill press when drilling a material. It is vital to use the correct size and appropriate drill bit style.

Engineering Tolerances. The most commonly used tolerancing system for shafts and holes is detailed in ISO 286-1 & 286-2. The first provides the charts for the fundamental deviations (G, j, etc.) and tolerance grades (7, 8, 9, etc.), out of which the limits of the tolerance classes (H7, g6, etc.) can be calculated.

The parallelism symbol is generally used to ensure features are aligned for proper function. In the left figure above, the boxed parallelism symbol and tolerance are used to control the center axis of a hole. The boxed symbols can be read "This axis must lie between two planes parallel to the axis A and spaced 0.3 apart".
A good design drawing can indicate all the details needed to produce a mechanical CNC milling part in an easy way. Because there is no large space on a drawing to contain all the text to illustrate the image, abbreviations, and symbols are often used in engineering drawings to communicate the characteristics of the product to be manufactured.
