C
UTS NOT ALLOWED
When the machine is used manually with certain data cards, it may not be possible to carry out certain
entered combinations. This happens when the cutting depths are not compatible in the order the user
entered the possible cuts.
Example:
1) Enter data card number
2) Press ENTER
3) Enter the cut
4) Press ENTER
The Silca software calculates the validity of the data
entered. If they are not cong ruous the fo llowing
message will appear:
NON-FEASIBLE
COMBINATION
This message is explained below.
The reason for th e conflict betwee n certa in cuts is
explained simply in the case shown.
With rega rd to the cut that origi nated the message
<NON-FEASIBLE COMBINA TION> it can be seen
that between the two deep cuts (8) and the constant
angle (100 °) the intermediate cut (0) wou ld be
removed.
This h appens wh en the cu tting an gle N (Normal) i s
not made variab le b y me ans of the type o f cu t L
(Laser).
The new drawing of the key shows how for the same
cutting process (808 46) th e cutting angles are
automatically ca lculated b y the conjunction of the
cutting base with a straight line.
This aspect, admissible with certain car keys, is mo re
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 combi nations in the Option s menu can in an y case be disabled (Cutting check -
cap.5.9).
