Points P1 and P2 can then be described – with reference to the pole – as follows:
Position Polar coordinates
P1 RP=100 AP=30
P2 RP=60 AP=75
RP: Polar radius
AP: Polar angle
2.1.1.4 Absolute dimensions
Position specifications in absolute dimensions
With absolute dimensions, all the position specifications refer to the currently valid zero point.
Applied to tool movement this means:
the position, to which the tool is to travel.
