Polar radius RP
The polar radius remains stored until a new value is input.
If the modally active polar radius is RP = 0
The polar radius is calculated from the distance between the starting point vector in the polar
plane and the active pole vector. The calculated polar radius is stored modally afterwards.
This applies irrespective of a selected pole definition such as G110, G111, G112. If both
points are programmed identically, this radius becomes 0 and alarm 14095 is generated.
If a pole angle AP is programmed with RP = 0
If the current block contains a polar angle AP rather than a polar radius RP and if there is a
difference between the current position and pole in workpiece coordinates, then this
difference is applied as the polar radius and stored modally. If the difference = 0, the pole
coordinates are specified again and the modal polar radius remains zero.
4.3 Rapid traverse movement (G0, RTLION, RTLIOF)
Function
You can use the rapid traverse movements to position the tool rapidly, to travel round the
workpiece or to approach tool change locations.
Non-linear interpolation is activated using RTLIOF parts program commands; linear
interpolation is activated using RTLION.
Note
This function is not suitable for workpiece machining!
