G63: Multiple machining in a circular pattern
10.4.1 Basic operation
1. Multiple machining calculates the next point of those programmed where it is wished to machine.
2. Movement at the feedrate programmed by "C" (G00, G01, G02 or G03) to this point.
3. Multiple machining will perform the canned cycle or modal subroutine selected after this
movement.
4. The CNC will repeat steps 1-2-3 until the programmed path has been completed.
After completing multiple machining, the tool will be positioned at the last point along the
programmed path where machining was performed.
Programming example assuming that the work plane is formed by the X and Y axes, that the Z axis
is the longitudinal axis and that the starting point is X0 Y0 Z0:
It is also possible to write the multiple machining definition block in the following ways:
G63 X200 Y200 K12 C1 F200 P2.004 Q8
; Canned cycle positioning and definition.
G81 G98 G01 G91 X280 Y130 Z-8 I-22 F100 S500
; Defines multiple machining.
G63 X200 Y200 I30 C1 F200 P2.004 Q8
; Cancels the canned cycle.
