Cycle parameters

Type of approach/departure

Q390: Definition of the

type of approach or departure.

Q390 = 1:
Approach the contour tangentially on a circular arc.

Q390 = 2:
Approach the contour tangentially on a straight line.

Q390 = 3:
Approach the contour at a right angle.

Radius compensation (0=R0/1=RL/2=RR)

Q391:

Definition of the radius compensation:

Q391 = 0:
Machine the defined contour without radius
compensation.

Q391 = 1:
Machine the defined contour with compensation to
the left.

Q391 = 2:
Machine the defined contour with compensation to
the right.

Approach/departure radius

Q392: Only in effect if

tangential approach on a circular path was selected.
Radius of the approach/departure arc. Input range 0 to
99999.9999

Center angle

Q393: Only in effect if tangential

approach on a circular path was selected. Angular
length of the approach arc. Input range 0 to
99999.9999

Distance to auxiliary point

Q394: Only in effect if

tangential approach on a straight line or right-angle
approach was selected. Distance to the auxiliary point
from which the TNC is to approach the contour. Input
range 0 to 99999.9999
