A variety of geometric information is computed by the postprocessor. This geometric information can be used as $PP entries. This provides for various methods of representing geometric information for different types of controllers.
The following describes the different types of geometric entries allowed in the $PP file:
ANGLE |
Angle from start point to end point in degrees. |
DIR0 |
Direction of arc, 0 if counterclockwise 1 if clockwise. |
DIR1 |
Direction of arc, -1 if counterclockwise 1 if clockwise. |
EA |
End angle of arc in degrees. |
LENGTH |
Length of line or arc. |
RADIUS |
Radius of arc. |
FRADIUS |
This is the radius of the current arc/circle but it will be negative if the sweep is greater than 180 degrees. |
SA |
Start angle of arc in degrees. |
SWEEP |
Sweep of arc in degrees, positive if counterclockwise, negative if clockwise. |
X |
Current cutter position in X. Absolute or incremental depending on mode. |
X1A |
Absolute X coordinate of start point of arc, line, point. |
X2A |
Absolute X coordinate of end point of arc, line. |
X2I |
Incremental X coordinate of end point of arc, line. |
XA |
Current absolute cutter position in X. |
XC |
X coordinate of center of arc. Absolute or incremental depending on mode. |
XCA |
Absolute X coordinate of center of arc. |
XCI |
Incremental X coordinate of center of arc. |
XI |
Current incremental cutter position in X. |
Y |
Current cutter position in Y. Absolute or incremental depending on mode. |
Y1A |
Absolute Y coordinate of start point of arc, line, point. |
Y2A |
Absolute Y coordinate of end point of arc, line. |
Y2I |
Incremental Y coordinate of end point of arc, line. |
YA |
Current absolute cutter position in Y. |
YC |
Y coordinate of center of arc. Absolute or incremental depending on mode. |
YCA |
Absolute Y coordinate of center of arc. |
YCI |
Incremental Y coordinate of center of arc. |
YI |
Current incremental cutter position in Y. |
Z |
Current cutter position in Z. Absolute or incremental depending on mode. |
ZA |
Current absolute cutter position in Z. |
ZI |
Current incremental cutter position in Z. |
