3.31.4 Outer Circle Fine Milling Cycle (G114/G115)
Format: G114/G115 X_ Y_ Z_ R_ I_ J_ D_ F_ ;
X_Y_: The starting point in XY plane
Z_ : The distance from point R to the bottom of the hole
R_ : The distance from the initial level to point R level
I_ : Radius of Fine Milling Circle
J_ : Distance from fine milling start point to circle center
D_ : Tool radius offset number
F_ : Cutting Feedrate
Note: 1. Radius of fine milling circle, I, Its absolute value is used if it is negative.
2. Distance from fine milling starting point to circle center, J, Its absolute value is used if it is negative.
3. Allowance for fine milling isn't less than 0, otherwise absolute value of negative number.
4. Range of Tool radius offset number , D, is 0~32. default is 0.
Command Path:
G114: CCW Outer Circle Fine Milling Cycle G115: CW Outer Circle Fine Milling Cycle
Command Path:
(1) Rapid positioning to a location within XY plane ;
(2) Rapid down to R level ;
(3) Feed to the bottom of hole
(4) Circular interpolation by the transition arc 1 from the starting point ;
(5) Circular interpolation for the whole circle by the path of arc 2 and arc 3 ;
(6) Circular interpolation by transition arc 4 and return to the starting point ;
(7) Return to the initial level(G98) or point R level (G99) .
In outer circle 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.
