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 Groove Round
W_ : Depth of 1st cutting feed, distance from point R level
Q_ : Depth of each cutting feed
K_ : Incremental Width
V_ : Height between unprocessed surface and cutter
E_ : Allowance for fine groove
D_ : Tool radius offset number
F_ : Cutting Feedrate
Note: 1. Radius of groove round, I, should be greater than radius of current tool.
2. Depth of 1st cutting feed, W, should be greater than 0. If depth of 1st cutting feed exceeds the groove
bottom, then the machining is performed at the groove bottom;
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.
Fig3.31.2 Path of Inner Circle Groove Roughing Cycle
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, then feed to circle center,
(4) Mill the circle surface with a radius (I) hectically outward from the center by an increment
(K) each time;
(5) Return to point R level along Z axis;
(6) Axis X and Y rapidly position to the starting point;
(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 circle surface is finished;
(10) Return to point R level (G99);or return to initial level(G98).
Example : Rough milling an inner circle groove using the canned cycle code G110, as shown in the
figure below: (D1=5).
