8.3.5 Entering the master dimension
If you would like to finish your workpiece to an exact fit, you can input the master dimension
directly into the parameter screen form during programming.
Specify the master dimension as follows:
F<Diameter/Length> <Tolerance class> <Tolerance quality>
"F" identifies that a master dimension follows, i.e. in this case, a hole.
Example: F20h7
Possible tolerance classes:
A, B, C, D, E, F, G, H, J, T, U, V, X, Y, Z
Upper-case characters: Holes
Lower case letters: Shafts
Possible tolerance qualities:
1 to 18, if they are not restricted by DIN standard 7150.
