3.3 Absolute dimension for rotary axes (DC, ACP, ACN)
With the above parameters you can define the desired approach strategy for positioning
rotary axes.
Programming
A=DC(…) B=DC(…) C=DC(…)
Or
A=ACP(…) B=ACP(…) C=ACP(…)
Or
A=ACP(…) B=ACP(…) C=ACP(…)
Parameters
A B C
Axis identifier for rotary axis to be traversed
DC
Absolute dimensions, approach position directly
ACP
Absolute dimensions, approach position in positive direction
ACN
Absolute dimensions, approach position in negative direction
Example of milling
Machining on a rotary table: The tool is stationary, the table rotates through 270° in
clockwise direction. to produce a circular groove.
