Peripheral surface/Peripheral surface C - Cartesian:
Y
End point in Y direction (abs. or inc.) – (calculated from Yα or vice versa)
Incremental dimensions: The plus/minus sign is evaluated.
Yα End angle (abs. or inc.) – (calculated from Y or vice versa)
Incremental dimensions: The plus/minus sign is evaluated.
Z End point in the Z direction (abs. or inc.)
Incremental dimensions: The plus/minus sign is evaluated.
L Length of straight line
α1
Starting angle to Y axis
α2
Angle to preceding element
Tangential transition: α2=0
Peripheral surface/Peripheral surface C and Peripheral surface Y – Polar:
L1 abs: distance between pole and end point
inc: distance between final point and end point
Incremental dimensions: The plus/minus sign is evaluated.
