Input Possibilities - HEIDENHAIN TNC 620 User Manual

Path contours – FK free contour programming (option 19)

Input possibilities

End point coordinates
Soft keys Known data
Cartesian coordinates X and Y
Polar coordinates referenced to FPOL
Example NC blocks
N70 FPOL X+20 Y+30*
N80 FL IX+10 Y+20 G42 F100*
N90 FCT PR+15 IPA+30 DR+ R15*
Direction and length of contour elements
Soft keys Known data
Length of a straight line
Gradient angle of a straight line
Chord length LEN of an arc
Gradient angle AN of an entry tangent
Center angle of an arc
Caution: Danger to the workpiece and tool!
Gradient angles you defined incrementally (IAN) are
referenced by the TNC to the direction of the last
traversing block. Programs that contain incremental
gradient angles and that were created on an iTNC
530 or on earlier TNCs are not compatible.
Example NC blocks
N20 FLT X+25 LEN 12.5 AN+35 G41 F200*
N30 FC DR+ R6 LEN 10 AN-45*
N40 FCT DR- R15 LEN 15*
