Machining direction during range selection:
■ By key or soft key: The sequence of selection
determines the machining direction
■ Touch pad:
Left mouse key – machining direction is the direction of
contour creation;
Right mouse key – machining direction is opposed to the
direction of contour creation
6.12.2 Cutting Data
■ The cutting speed, main and auxiliary feed rate are
determined from the material and the tool data.
Check/optimize the values
■ Maximum cutting depth P is adopted as cycle
parameter.
■ Define the coolant and coolant circuit

6.12.3 Cycle specification
Menu item ”Cycle - ...”
Machining range: Use the range selection function
to set the area to be machined.
Cycle parameter: Check/optimize the parameters.
Approach: The tool moves at rapid traverse from the
current position to the tool change position – before
the cycle is called.
The ”Approach” function is not contained in drilling
and threading cycles. Place the tool on a suitable
position using the ”Approach” function.
Retract: After the cycle is finished, the tool moves at
rapid traverse to the retraction position.
Move to tool change position: After the cycle is
finished or after ”retraction,” the tool moves at rapid
traverse to the change position. The change position
defined in the dialog box is evaluated only when
”WP=1” (machining parameter 2).
The traverse type (G0 or G14) and the tool change
position are defined in machining parameter 2.
