2D pockets
11.1 2D pockets
The G66 function is not modal, therefore it must be programmed whenever it is required to perform
a 2D pocket. In a block defining an irregular pocket canned cycle, no other function can be
programmed, its structure definition being:
G66 D H R I F K S E Q
D (0-9999) / H (0-9999) Drilling operation
Label number of the first block (D) and last block (H) defining the drilling operation.
• When not setting (H) only block (D) is executed.
• When not setting (D) there is no drilling operation.
R (0-9999) / I (0-9999) Roughing operation
Label number of the first block (R) and last block (I) defining the roughing operation.
• When not setting (I) only block (r) is executed.
• When not setting (R) there is no roughing operation.
F (0-9999) / K (0-9999) Finishing operation
Label number of the first block (F) and last block (K) defining the finishing operation.
• When not setting (K) only block (F) is executed.
• When not setting (F) there is no finishing operation.
S (0-9999) / E (0-9999) Geometric description of the profiles
Label number of the first block (S) and last block (E) defining the geometry of the profiles forming
the pocket. Both parameters must be set.
Q (0-999999) Program that contains the definition of the geometrical description of the profiles
Number of the program containing the geometry definition, parameters S and E. If it is in the same
program, (Q) need not be defined.
