6.5.9 Parameter description of straight line/circle contour elements

Parameters Contour element "Straight line"
X absolute Absolute end position in X direction
X incremental Incremental end position in X direction
Y absolute Absolute end position in Y direction
Y incremental Incremental end position in Y direction
L Length of line
a1 Pitch angle referred to X axis
a2 Angle to preceding element;tangential transition: a2=0
Transition to Transition element to next contour is a chamfer (FS)
following Transition element to next contour is a radius (R)
element FS=0 or R=0 means no transition element
Parameters Contour element "Circle"
X absolute Absolute end position in X direction
X incremental Incremental end position in X direction
Y absolute Absolute end position in Y direction
Y incremental Incremental end position in Y direction
a1 Starting angle referred to X axis
a2 Angle to preceding element; tangential transition: a2=0
End angle referred to X axis
b1
Angle of aperture of circle
b2
Direction of In clockwise or counter-clockwise direction
rotation
R Radius of circle
I Position of arc center point in X direction (abs. or incr.)
J Position of arc center point in Y direction (abs. or incr.)
Transition to Transition element to next contour is a chamfer (FS)
following Transition element to next contour is a radius (R)
element FS=0 or R=0 means no transition element
