SINUMERIK 840D sl Operation/Programming ShopTurn (BAT) – 08/2005 Edition
When you have removed stock from a pocket (with/without islands)
and residual material remains in place, this is automatically detected
by ShopTurn. You can use a suitable tool to remove this residual
material without having to machine the whole pocket again, i.e.
avoiding unnecessary idle motions.
Material that remains as part of the finishing allowance is not residual
material.
The residual material is calculated on the basis of the milling cutter
used for stock removal.
If you mill several pockets and want to avoid unnecessary tool
changeover, remove stock from all the pockets first and then remove
the residual material. In this case, for removing the residual material,
you also have to enter a value for the "Reference tool TR" parameter
that appears when you press the "All parameters" softkey. Then
program as follows:
1. Contour pocket 1
2. Remove stock
3. Contour pocket 2
4. Remove stock
5. Contour pocket 1
6. Solid machine residual material
7. Contour pocket 2
8. Solid machine residual material
The "Residual material" function is a software option.
Press the "Milling", "Contour milling" and "Pocket resid. mat." soft
Contour
keys.
