3.31.3 Inner Circle Groove Fine Cycle (G112/G113)
The tool fine mills a full circle within a circle by the specified radius I and the specified
direction, and it returns after finishing the fine milling.
G112: CCW Inner Circle Groove Fine Cycle ; C113: CW Inner Circle Groove Fine Cycle .
Format: G112/G113 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.
Process of Cycle:
1) Rapid positioning to the position in XY plane;
2) Rapid down to point R level ;
3) Feed to the machining start point at the bottom of hole ;
4) Arc Interpolation by the transition arc 1 from the starting point;
5) Circle Interpolation for the whole circle by inner arc path of finish-milling ;
6) Circle Interpolation by transition arc 4 and return to the starting point ;
7) Return to the initial level or point R level according to G98/G99.
