7.5 Path contours – Polar coordinates
Overview
With polar coordinates you can define a position in terms of its
angle PA and its distance PR relative to a previously defined pole
CC.
Polar coordinates are useful with:
Positions on circular arcs
Workpiece drawing dimensions in degrees, e.g. bolt hole circles

+ Straight line Polar radius, polar angle of the
straight-line end point

+ Circular path around circle
center/pole to arc end point
Polar angle of the arc end point,
direction of rotation
302
+ Circular arc with tangential
connection to the preceding
contour element
Polar radius, polar angle of the
arc end point

+ Combination of a circular and a
linear movement
Polar radius, polar angle of the
arc end point, coordinate of the
end point in the tool axis
