Arbitrary Positions (Cycle802) - Siemens SINUMERIK 840D sl Operating Manual

Tool traverse path
● ShopMill
The programmed positions are machined with the previously programmed tool (e.g. center
drill). Machining of the positions always starts at the reference point. In the case of a grid,
machining is performed first in the direction of the 1st axis and then meandering back and
forth. The frame and circle or pitch circle are machined counter-clockwise.
● G code
For G code, for rows/frames/grids, a start is always made at the next corner of the frame
or grid or the end of the row. The frame and circle or pitch circle are machined counter-
clockwise.
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.
With an A or B axis, a work offset is to be defined:
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
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.

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 softkey "Delete all" to delete all positions programmed in X/Y.
