Finishing
2-channel finish cutting is only possible with Balance Cutting.
Only one machining program is generated for the leading channel, and this is executed there.
The motion in the following channel is coupled to this motion.
Balance Cutting
Balance Cutting involves symmetrical machining in both channels. In so doing, the cutting
forces are evenly distributed between both sides of the workpiece. The tools are opposite one
another at the same infeed depth.
Machine manufacturer
Please refer to the machine manufacturer's specifications on the subject of axis cou‐
pling.
Note
Tools
The tool radii or cutting plate widths of the plunging tools must be the same size.
General conditions
● For internal machining operations ensure that collisions do not occur between the tools and/
or tool carriers. The control cannot ensure this, as it has no information about the
mechanical dimensions.
● Before machining for the first time, position the tools so that they are in approximately in the
same position.
● The tools must have the same cutting-edge position and cutting direction in both channels.
● The following parameters and settings must be the same in both channels:
– the machining plane (G17, G18, G19),
– the technology (stock removal),
– the machining (roughing, finishing),
– the dimension unit (metric, inch).

Job list
One example for a ShopTurn and one for a G Code job list are described in the following.
The clock symbol in the icon of the program blocks indicates that internal WAIT commands are
used to synchronize the channels involved. The cycles perform the synchronization.
