Programming
1. The cycle movement is executed by X(W) and P( Δ i) blocks of G75, and the movement
is not executed if only “G75 R(e) ; ” block is executed;
2. Δ d and e are specified by the same address R and whether there are X(U) and P( Δ i)
words or not in blocks to distinguish them;
3. The tool can stop in Auto mode and traverse in Manual mode when G75 is executed,
but the tool must return to the position before executing in Manual mode when G75 is
executed again, otherwise the following path will be wrong;
4. When the system is executing the feed hold or single block, the program pauses after
the system has executed end point of current path;
5. R( Δ d) must be omitted in grooving, and so there is no tool retraction clearance when
the tool cuts to radial cutting end point.
Example
：
Program (suppose the grooving tool width is 4mm, the system least increment is 0.001mm):
O0008;
G00 X150 Z50 M3 S500; (Start spindle with 500 r/min)
G0 X125 Z-24; (Position to starting point of machining)
G75 R0.5 F150; (Machining cycle)
G75 X40 Z-50 P60000 Q30000; (X tool infeed 6mm every time, tool retraction 0.5mm,
rapid returning to starting point (X125) after infeeding
to end point (X40), Z tool infeed 3mm and cycle the
above-mentioned steps to continuously run programs)
G0 X150 Z50; (Return to starting point of machining)
M30; (End of program)
3.22.7 Drilling Cycle G83 or G87
Command format ： axle drilling G83 X(U)__ C(H)__ Z(W)__ P__ Q__ R__ F__ K__M__ J0/1 ；
radial drilling G87 Z(W)__ C(H)__ X(U)__ P__ Q__ R__ F__ K__ M__ J0/1
；
Code meaning: Drilling Cycle: Rapid traverse to the drilling position from start, then perform it
along with the drilling hole direction) feed, retraction, re-feed… till to the botton of a
hole, and then retreact to the drilling position, a drilling cycle is then completed;
Position to the drilling position again, and then perform the next drilling cycle; stop at
the drilling position after the last drilling operation is performed, the drilling cycle is
then completed. The drilling cycle divides into axial drilling G83 and radial drilling G87,
which is used in the axial drilling (Z axis) and radial drilling (X axis) separately.
