SPECIAL CASES
• Cutting a key with two asymmetrical sides
Operational keys: use the [up/down] arrow keys to be able to visualize all data.
Proceed with the cutting process.
• Cuts not allowed
When the machine is used manually with certain data cards, it may not be possible to carry out certain entered combina-
tions. This happens when the cutting depths are not compatible in the order the user entered the possible cuts.
Example:
After entering the cutting combination the Silca software calculates
the validity of the data. If there is inconsistency, when the ENTER key
is pressed the following message appears:
This message is explained below.
The reason for the conflict between certain cuts is explained simply in
the case shown.
With regard to the cut that originated the message <NON-FEASIBLE
COMBINATION> it can be seen that between the two deep cuts (8)
and the constant angle (100°) the intermediate cut (0) would be
removed.
This happens when the cutting angle N (Normal) is not made variable
by means of the type of cut L (Laser).
Fig. 25
The new drawing of the key shows how for the same cutting process
(80846) the cutting angles are automatically calculated by the conjunc-
tion of the cutting base with a straight line.
This aspect, admissible with certain car keys, is more commonly
known as ‘the ideal cutting line’.
ATTENTION: in this example it can be seen that the ß angle is less
than 45°. This could cause serious problems with a lock, making it
difficult or impossible to place the key into the cylinder or remove it.

Control of the combinations in the Options menu can in any case be disabled.
