5.6.12 Removing residual material from a contour spigot
When you have milled a contour spigot 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 spigot 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 clearing.
If you mill several spigots and want to avoid unnecessary tool
changeover, clear all the spigots 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 blank 1
2. Contour spigot 1
3. Clear spigot 1
4. Contour blank 2
5. Contour spigot 2
6. Clear spigot 2
7. Contour blank 1
8. Contour spigot 1
9. Clear residual material spigot 1
10. Contour blank 2
11. Contour spigot 2
12. Clear residual material spigot 2
The "Residual material" function is a software option.
