3.31.8 Inner Rectangle Groove Fine Milling Cycle (G136/G137)
The tool fine milling within a rectangle by the specified width & direction, and it returns after
finishing the fine milling.
G136:CCW Inner Rectangle Groove Fine Milling Cycle ; C137:CW Inner Rectangle Groove
Fine Milling Cycle .
Format: G136/G137 X_ Y_ Z_ R_ I_ J_ D_ K_ U_ 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_ :
Width of rectangle in X-axis
J_ :
Width of rectangle in Y-axis
K_ :
Distance from fine milling start point to rectangle side in X-axis
U_ :
Corner arc radius
D_ :
Tool radius offset number
F_ :
Cutting Feedrate
Note: 1. Width of rectangle in X-axis, I, Range is -99999999~99999999 (*min unit). Its absolute value is used if
it is negative.
2. Width of rectangle in Y-axis, J,Range is -99999999~99999999 (*min unit). Its absolute value is used if
it is negative.Value of J must be not less than diameter , otherwise alarm.
3. Distance from fine milling starting point to rectangle side in X-axis,K,is greater than radius of tool. Its
absolute value is used if it is negative.
4. No corner transition if corner arc radius, U, is omitted. System will alarm when U is omitted or 0 &
tool radius is less than 0.
5. Range of Tool radius offset number , D, is 0~32. default is 0.
Command Path:
G136:CCW Inner Rectangle Groove Fine Cycle
C137:CW Inner Rectangle Groove Fine Cycle
Process of Cycle:
1) Rapid positioning to the position in XY plane;
2) Rapid down to point R level ;
3) Cutting Feed to the machining start point at the bottom of hole ;
4) Perform arc interpolation by the transition arc 1 from the starting point;
5) Perform linear & circle interpolation by the path 2-3-4-5-6 ;
6) Perform circle interpolation by transition arc 7 and return to the starting point ;
7) Return to the initial level or point R level according to G98/G99.
