2.6 G165. Multiple machining in a chord pattern
With this function, it is possible to execute the active machining operation at the point
programmed with an arch chord. The cycle will only execute one machining operation will
be executed and its programming format is: When defining the machining operation, only
use one parameter of the group "A" and "I".
G165 X Y A I C F
Parameters "X" and "Y" define the center of the circle, same as "I" and "J" in circular
interpolations (G02, G03).
X Distance from the starting point to the center along the abscissa axis.
Y Distance from the starting point to the center along the ordinate axis.
When defining the machining operation, only one of parameters "A" and "I" is required.
A Angle, in degrees of the perpendicular bisector of the chord with respect to the abscissa axis.
I Length of the chord.
When the movement between points is done in G00 or G01, the sign indicates the direction:
"I+" counterclockwise and "I-" clockwise.
C It indicates how it will move between the machining points. If not programmed, a value of C
= 0 is assumed.
C=0 In rapid (G00).
C=1 Linear interpolation (G01).
C=2 In clockwise circular interpolation (G02).
C=3 In counterclockwise circular interpolation (G03).
F Feedrate for the movement between points. It will only be valid for "C" values other than zero.
Basic operation
Multiple machining is executed as follows:
1 The multiple machining calculates the programmed point to machine.
2 Movement to that point at the feedrate programmed with "C" (G00, G01, G02 or G03).
3 The multiple machining will execute the selected canned cycle after the movement.
After the multiple machining, the tool will remain positioned at the programmed point.
