Function and input
Behavior of the polar kinematics at radius 0
If the tool center of a machine with polar
kinematics lies exactly on the polar axis (C axis,
radius 0), there are two possibilities for a linear
positioning block: r,phi or -r,phi+180.
Use this parameter to define the behavior of the
MANUALplus 620 if the tool center point path
runs through (crosses) the polar axis.
Format: Selection menu
Input:
RadiusPositive:
After crossover, the tool center point is at a
position with positive radius.
RadiusNegative:
After crossover, the tool center point is at a
position with negative radius.
MinimalAngle:
The crossover path is executed through a C-axis
movement as small as possible.
NoChangeOfRadius:
After crossover, the radius has the same
algebraic sign as before crossover.
Radius0NotAllowed:
A tool center point path that runs through
(crosses) the polar axis is not allowed.
