A SIMPLE WAY to measure the tolerances of the shape and location of the surfaces!

There are dimensional tolerances on any drawing of the part. But in some drawings there are also tolerances for the shape and location of surfaces, which are sometimes difficult to measure without special control devices. But there are options for universal measurement of shape and location tolerances, which are used in production workshops today. Do not be afraid of a large abundance of technical requirements and tolerances for the location and shape of surfaces in the drawing. Most of them are obtained simply by using the control program of your CNC machine, by machining in one installation, or by saving the bases.
