Case 4 – Tooth Thickness at Selected Point
In this case the switches for the normal chordal tooth thickness in the flank
generation input screen are turned on as indicated with the red arrows in
Figure 14 and the user selected tooth thickness coordinate in axial direction
as well as the coordinate position in radial direction are typed in the input tabs.

After this, “Run Flank Generation” has to be clicked in order to generate the
appropriate CMM download file.

for selected point

In case 4, the CMM grid has an equal distribution of columns and rows except
for the chosen measurement point of the tooth thickness (see Figure 15). The
angular tooth thickness between the two distorted grid points is converted by
the new applet in the Dimension-Sheet program in a normal chordal tooth
thickness. If the Dimension-Sheet calculation is activated after the switches in
Figure 14 are set to “On”, the chosen coordinates are entered and the flank
generation conducted, then the dimension sheet output will show in part 6 in
Figure 16 the normal chordal tooth thickness, the axial distance of the tooth
thickness points from the crossing point of the respective member and the
chordal addendum, In case 4 the tooth addendum and the face width position
reflect the chosen tooth thickness measurement location
