6.8 C-Axis Cont
ours
Lateral surface: Circular element
This function defines a circular arc on a lateral surface.
Call the arcs menu.
Select the direction of rotation.
Enter the arc dimensions and define the transition to the next element.
Parameters
End point of arc
Z End point
P End point – polar
CY End point – angle as “linear dimension”
C End point – angle
Center of arc
K Center
CJ Center point (angle as “linear dimension”)
b Center point in polar coordinates (reference angle:
positive XK axis)
PM Center point – polar
Other parameters
R Arc radius
Tangential/nontangential: Specify the transition to the
next contour element
WA Angle between positive Z axis and tangent in starting point of
arc
WE Angle between positive Z-axis and tangent in end point of arc
WV Counterclockwise angle between preceding element and
tangent in starting point of arc. If the preceding element is an
arc: Angle to the tangent.
WN Counterclockwise angle between tangent in arc end point
and following element. If the following element is an arc:
Angle to the tangent.
