7.2 Blade Expansion
There are three blade expansion parameters that are set in the Setup &
Diagnostics workbook to monitor blade expansion.
To access the blade expansion parameters:
• In the Setup & Diagnostics workbook, select Saw > Dicer > Cutting
Block. The blade expansion parameters appear on the parameters list.
The following is a list and explanation of the blade expansion parameters:
• Max. Blade Expansion: The amount that the blade is permitted to
expand between Height procedures until a response is triggered.
• Max. Blade Expansion after init: The amount that the blade is
permitted to expand between Height procedures after initialization
until a response is triggered.
• Button Height/NCHD Repetitions: The number of times the Height
procedure is repeated if the blade expansion value is beyond the Max.
Blade Expansion or the Max Wear value.
If the Max. Blade Expansion parameter has been surpassed during the
Height procedure more times than allowed by the Button Height/NCHD
Repetitions parameter, a message with three options appears:
• Retry: The System performs the Height procedure again to measure
the expansion of the blade.
• Accept: The System accepts the measured blade expansion as the new
value for Max. Blade Expansion.
• Cancel: The error message "Blade is bigger than expected” appears.
The User can continue the cutting process by pressing either Run or
Full Wafer Cut.
Note: It is important to repeat the Height procedure in case the blade
surpassed the maximum expansion on the first reading due to excess dirt or
water on the blade.
