11.2.3 Finishing operation
This operation is optional.
It will be programmed in a block that will need to bear a label number in order to indicate to the canned
cycle the block where the finishing operation is defined.
The function for the finishing operation is G68 and it cannot be executed independently from the G66.
Their programming formats are:
G68 B L Q J I R V F S T D M
[ B5.5 ] Drilling peck (step)
Defines the pass in the plane between two 3D paths of the finishing operation. It must be defined
and with a value other than "0".
[ L±5.5 ] Lateral finishing stock
Defines the value of the finishing stock on the side walls of the pocket left by the roughing and semi-
finishing operations. There is no finishing stock left on top of the islands nor on the bottom of the
pocket.
If programmed with a positive value, the finishing pass will be carried out in square corner (G07).
If a negative value is programmed, the finishing pass will be carried out in G5 (round corner). If not
programmed, the cycle assumes "L0".
[ Q 0/1/2 ] Direction of the finishing pass
Indicates the direction of the finishing pass.
Q= 1: All the passes will be inward from the top of the pocket to its bottom
Q= 2: All the passes will be outward from the bottom of the pocket to the top.
Q=0: Alternating direction for every 2 consecutive paths.
Any other value will generate the corresponding error message. If parameter "Q" is not programmed,
the cycle assumes Q0.
