Drilling (icon).
It indicates whether drilling
(a)
takes place before machining the
pocket or not
(b)
. It should be used when the roughing tool cannot
machine downwards.
Press the "Drilling" softkey to access the drilling cycle and after
defining it, press the "End" softkey to return to the 2D pocket cycle.
The diameter of the drilling tool must not exceed the radius of the
roughing tool: or that of the roughing at the bottom if there is no
roughing operation.
The cycle calculates the drilling point depending on the
programmed profile and the roughing tool.
Roughing parameters:
The roughing operation empties the pocket leaving the following
finishing stocks:
Both stocks are defined as finishing parameters.
The roughing operation defining parameters are:
δ Finishing stock on the side walls.
δz Finishing stock at the bottom of the pocket.
∆ Maximum milling pass or width.
The cycle recalculates the pass so that all the passes are
identical, with the same value as or smaller than the one
programmed.
If programmed with a 0 value, it assumes a value of 3/4 of the
diameter of the selected tool.
I Penetration step.
• If programmed with a positive sign (I+), the cycle
recalculates the step so all the penetrations are identical
with the same value as or smaller than the one programmed.
• If programmed with a negative sign (I-), the pocket is
machined with the given pass (step) except the last pass
that machines the rest.
In either case, the cycle limits the step to the cutting length
assigned to the tool in the tool table.
Fz Penetration feedrate.
