Arbitrary Positions (Cycle802) - Siemens SINUMERIK 828D Operating Manual

Programming technology functions (cycles)
9.1 Drilling
If an A or B axis is set up on your machine, this is supported during drilling (any position
pattern, full circle, and pitch circle).
You set as to which rotary axis is listed as selection in position patterns.
If the machine has an A or B axis, it makes sense to define a work offset:
X / Y = end face of the cylinder (X for an A axis / Y for a B axis)
X / Y = center point of the cylinder (Y for an A axis / X for a B axis)
Z = center point of the cylinder
The "cylinder" in this case refers to any part that is clamped in the A/B axis.
Cylinder surface transformation
When working with the cylinder surface transformation, please note that the A axis or B axis
is not supported in all cases. Programming of any position in the XYA plane is not possible
while cylinder surface transformation is active.
Note
A work offset in the rotary axis A or B is effective even while cylinder surface transformation
is active.
9.1.11

Arbitrary positions (CYCLE802)

Function
The "Arbitrary positions" function allows you to program any positions, i.e. in rectangular or
polar coordinates. Individual positions are approached in the order in which you program
them.
Press "Delete all" softkey to delete all positions programmed in X/Y.
Rotary axis
ZC plane
You program in ZC to prevent the Y axis moving during machining.
To ensure that the holes point to the center of the "Cylinder", you must first position the Y
axis centrally above the "Cylinder".
