HEIDENHAIN CNC Pilot 4290 - Manual (Page 262)

6 TURN PLUS 250
Circular arc in lateral surface contour
Use the menu symbol to select the direction of arc rotation and give
the arc a dimension.
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 parameters
K:
Center
CJ: Center (angle as linear dimension - reference: unrolled
cylinder at ”reference diameter”)
PM: Center point, polar
β:
Center (angle)
Other parameters
R:
Arc radius
Tangential/nontangential: Specify the transition to the
next contour element
Line segment in a lateral surface contour
Use the menu symbol to select the direction of the line and assign it a
dimension.
Parameters
Z:
End point of line
P: End point of the line - polar
CY: End point of the line - angle as ”linear dimension”
C: End point of the line - angle
W: Angle of the line (for reference see illustration)
WV: Angle to the preceding element
WN: Angle to the successor element
WV, WN:
■ The angle leads from the preceding/succeeding element
counterclockwise to the new element.
■ Arc as preceding/succeeding element: Angle to tangent.
L: Length of line
Tangential/nontangential: Specify the transition to the
next contour element
