Note
Constant cutting rate
When using a constant cutting rate, ensure that the offset (DCH) is not too high.
Tools
The difference between the two cutting radii of the tools must not exceed the
allowance.
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 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.
Please refer to the machine manufacturer's specifications on the subject of axis co

Note
Tools
The tool radii or cutting plate widths of the plunging tools must be the same size.
● 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).
