3D pockets
11.2 3D pockets
The cycle calling function G66 is not modal; therefore, it must be programmed every time a 3D pocket
is to be executed.
In a block defining an irregular pocket canned cycle, no other function can be programmed, its
structure definition being:
G66 R I C J F K S E
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.
C (0-9999) / J (0-9999) Semi-finishing operation
Label number of the first block (C) and last block (J) defining the semi-finishing operation.
• When not setting "J" only block "c" is executed.
• When not setting (C) there is no semi-finishing 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.
