==Problem==
 
The saw “Y drive” on a ZX5 is limited in its depth range to +/- 20mm from the centreline of the profile, and 20mm from the backfence. This is fine for most normal Y notching, but there are combinations when a particularly deep Y notch is required.
 
  
For example: Reversible windows - have a wide transom (84mm) and narrow outer frame (60mm){{#annotatedImageLight:Fichier:TB0434 Setting Up Deep Y notches on ZX5 434-1.jpg|0=649px|hash=|jsondata=|mediaClass=Image|type=frameless|align=center|src=https://stuga.dokit.app/images/8/89/TB0434_Setting_Up_Deep_Y_notches_on_ZX5_434-1.jpg|href=./Fichier:TB0434 Setting Up Deep Y notches on ZX5 434-1.jpg|resource=./Fichier:TB0434 Setting Up Deep Y notches on ZX5 434-1.jpg|caption=|size=649px}}

This gives a Y notch depth of 42mm in a 60mm wide profile, leaving 18mm “residual” square cut on the end. This is outside the minimum threshold of 20mm from the backfence and the saw centraliser would bottom out.
 
 
 
{{Info|...On an Autoflow Mk4, the minimum residual should be set to 26mm}}<br />
 
 
 
==Solution==
 
To solve this problem, the machine has an automatic feature to allow the use of a SQCUT to create the Y notch – this operation uses the 10mm datum tool to make a square slot on the machining centre side, and then the saw side cuts a mitre to finish it off.
 
 
 
The software has to increase the length of the part to allow for this, using the following calculations:
 
 
 
These calculations are done automatically from the dimensions of profile width and Y notch depth. The Y notch depth is taken from the tool code (YFL475 will give a 47.5mm depth), plus the globalYDepthAdjustment parameter.{{#annotatedImageLight:Fichier:TB0434 Setting Up Deep Y notches on ZX5 434-2.png|0=559px|hash=|jsondata=|mediaClass=Image|type=frameless|align=center|src=https://stuga.dokit.app/images/3/38/TB0434_Setting_Up_Deep_Y_notches_on_ZX5_434-2.png|href=./Fichier:TB0434 Setting Up Deep Y notches on ZX5 434-2.png|resource=./Fichier:TB0434 Setting Up Deep Y notches on ZX5 434-2.png|caption=|size=559px}}<br />
