Process of Cycle:
(1) Rapid positioning to the position in XY plane
(2) Rapid down to point R level
(3) Cut a depth (W) downward at the cutting speed by helical mode,
(4) Mill the rectangle surface hectically, outward from the center, with a incremental width (K)
each time;
(5) Cutter return to point R level along Z axis;
(6) Axis X and Y rapidly position to the center of rectangle;
(7) Rapid traverse to V , the distance to the unprocessed end surface;
(8) Cut a depth(Q+V) downward along Z axis;
(9) Repeats the operation (4)~(8) until the total depth of rectangle surface is finished;
(10) Return to point R level (G99);or return to initial level(G98).
Note: 1. P, L is invalid when using G134/G135, but value of P will be remained as canned cycle.
2. When use G134/G135 is used, G codes in 01 group cannot be used, otherwise G134/G135 is replaced by
other codes in group 1.
3. Tool radius compensation: in the fixed cycle command, the tool radius compensation is ignored, the
system calls the tool radius compensation specified by the program during the tool infeed.
Example
: Rough milling an inner rectangle groove using the canned cycle code G134, as shown in
the figure below: (D1=5, Length of rectangle =70 , Width of rectangle =50mm).
