5.4 Creating an ICP contour
Fits and inside threads
With the Inside thread fit soft key, you can display an input form
for calculating the machining diameter for fits and inside threads. After
entering the required values (nominal diameter and tolerance class or
thread type), you can apply the calculated value as the target point for
the contour element.
Calculate the fit for a hole or shaft:
 Press the Fit soft key
 Enter the nominal diameter
 Enter the fit data in the Fit form
 Press the ENT key to calculate the values
 Press the Apply soft key. The calculated center of tolerance is
entered in the corresponding field of the open dialog box
Calculate the core hole diameter for inside threads:
 Press the Inner thread soft key
 Enter the nominal diameter
 Enter the thread data in the Inside thread calculator form
 Press the ENT key to calculate the values
 Press the Apply soft key. The calculated core hole diameter is
entered in the corresponding field of the open dialog box
The machining diameter can only be calculated for suitable
contour elements, e.g. for a linear element in X direction
when calculating the fit for a shaft.
When calculating inside threads of thread type 9, 10 or 11,
you can select the nominal diameter for inch threads in the
Nominal diameter list L.
