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.
A fit calculator supports you when making entries.
Position the cursor on the desired entry field.
The calculator is displayed.
Press the "Fit shaft" or "Fit hole" softkey.
"F" (for hole) or "f" (for shaft) is automatically inserted in front of the
entry fields for diameter or length data, tolerance class and tolerance
quality.
Enter the diameter or length value in the first field.
In the second field, select the tolerance class and in the third field, enter
the tolerance quality.
Press the equals symbol on
the calculator.
