SPCview™ #009 - Peak location
Figure # 77 - Location of the blanking peak
Description:
This feature returns the location (degrees or position off BDC) of the maximum Peak between the
start and the end of a defined window (not the data collection window of the tool). If there are
multiple peaks in the window, only the location of the greatest peak will be returned. Note that a
peak is defined as a point at which the slope of the signature changes from positive on the left to
negative on the right.
Parameters:
Selected channel data to calculate the location of a peak from, can be real or virtual
Window start, in degrees or position off BDC
Window end, in degrees or position off BDC
Position units - degrees, or position off BDC.
Use:
In this example, the location of the peak is being used as a measure of the blank thickness. In the
case that a thicker blank is used, the location of the peak would move to the left. For thinner
blanks, the location of the peak would move to the right. The location of the peak for the blanking
operation should not be affected by the hardness of the material.
Error Check:
Refer to the "If a Programmed Feature Doesn’t Work" section below at page #101 for a
