Clinching points have a high repeatability. Their quality can be easily controlled through standardized measurement processes.
For the round point, the diameter and the length is controlled with calipers. The value obtained should be compared with the predetermined value included with the instruction manual of the machine. This is because it depends on the diameter of the punch, and on the thickness of sheet metal.
For the trapezoidal point, it is important to control the diameter of the point that is created in the interior part of sheet metal. This value has to be compared with the predetermined values included in the instruction manual of the machine. The dimensions depend on the width of the punch, and on the thickness of sheet metal.
