Command Path:
G138:CCW Outer Rectangle Fine Milling Cycle G139: CW Outer Rectangle Fine Milling Cycle
Command Path:
(1) Rapid positioning to a location within XY plane ;
(2) Rapid down to R level ;
(3) Cutting Feed to the bottom of hole
(4) Performs circular interpolation by the transition arc 1 from the starting point ;
(5) Performs linear & circular interpolation by the path 2-3-4-5-6 ;
(6) Performs circular interpolation by transition arc 7 and return to the starting point ;
(7) Return to the initial level(G98) or point R level (G99) .
In outer rectangle fine milling cycle, the interpolation directions of the transition arc and fine
milling arc are different. The interpolation direction in the code means the one of the fine milling.
Note: 1. Q, P, L is invalid when using G114/G115, but value of Q & P will be remained as canned cycle.
2. When use G114/G115 is used, G codes in 01 group cannot be used, otherwise G114/G115 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: Fine milling a outer rectangle pad that has been rough milled as follows by the canned
cycle code G138. (D1=5mm)
G90 G00 X50 Y50 Z50 ; Rapid positioning
G99 G138 X25 Y25 Z-50 R5 I80 J50 K30 U5 D1 F800 ; Outer rectangle fine milling
G80 X50 Y50 Z50 ; Cancel canned cycle and return from point R level
