Note
When input manually, the starting point can also be located outside the pocket. This can be
useful, for example, when machining a pocket which is open on one side. The machining
operation then begins without insertion with a linear movement into the open side of the
pocket.
8.3.11 Residual material contour pocket (CYCLE63)
Function
When you have removed stock from a pocket (with/without islands) and there is residual
material, then this is automatically detected. You can use a suitable tool to remove this
residual material without having to machine the whole pocket again, i.e. avoiding
unnecessary non-productive motion. 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 changes, 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, which,
for the ShopMill program, additionally appears when you press the "All parameters" softkey.
When programming, you must then proceed as follows:
1.
Contour pocket 1
2. Solid machining
3. Contour pocket 2
4. Solid machining
5. Contour pocket 1
6. Remove residual material
7. Contour pocket 2
8. Remove residual material
Software option
For solid machining residual material, you require the option "residual
material detection and machining".
